Hi Frank,

When leaves turn yellow it is usually due to a nutritional deficiency. An acidifying fertilizer such as Miracid may just do the trick.

Other possibilities include poor drainage and cold temperatures. Depending on where in Florida you are, cold is a possibility.

Hi Mervyn,

Gardenias like to be kept moist, but not soggy. They need to have soil that drains easily. As long as the water drains and your gardenias are outdoors, you can probably water them fairly often without a problem. However, if the soil stays soggy you should cut back a bit on your watering. Too much water can cause the roots to rot. If that happens, there is no hope for the gardenia.

As a rule of thumb, if the top inch of soil is dry, you need to water your gardenia. I hope that helps. You can read more in Gardenia Plant Care. In addition, if you put "gardenia" in the search box above, you'll get a whole list of helpful articles that I think you'll enjoy.

Thanks for visiting.

Dear Kathleen Many thanks for the tips. I use an hydranga fertiliser every 10/7 or so but I think it is the temperature that must be the killer. In January we get sun all day and the noon temperature is 40c+. We are just coming out of winter and it gets between 4-15c so that blows the gardenias ideal temperature out of the water. If they like full sun that would also explain why several other bushes my, ex, gardener moved to be in the shade are not doing so well. Talking of water how much do they need? Mervyn

Hi Mary,

Gardenias do like to be slightly root bound but if your has been in the same pot for eight years, it is time to repot it. Get a pot that is one size bigger than the one it is in. Get some good potting soil with peat moss as well.

Carefully remove your plant from its pot and gently loosen the roots slightly. Prune off any dead or damaged roots. Now put it in its new pot with some soil in the bottom and fill all around with more soil. Give it a good drink of water and you're done.

I have an established gardenia plant(potted) that was given to me about a year ago, it seems to be much healthier now. My question is there are some roots above the soil at the base of the plant and you can rock the plant a bit. Should I cover those roots or what should I do? Also when they are this old maybe 8 yrs old how often do you repot. Thanks would love to keep this going!

If you are going to prune your gardenias, and you don't have to prune them if you don't want to, it should be done right after blooming is done. If you wait too long you could be pruning off next years blossoms. Learn more by reading Pruning Gardenias and Gardenia Pruning.

Hi Pat,

Bud drop is usually cased by a lack of humidity. Try putting your pot in a tray of pebbles and fill the try with water. As the water in the tray evaporates, your gardenia will get needed humidity without getting wet (which can contribute to fungal growth on leaves). Still water it as needed and add water to the tray as it evaporates.

It is also possible that your gardenia isn't getting the right amount of water or the water isn't regular. Depending on your climate, you may need to water daily or every other day. Just be sure that the pot has drain holes so you don't have to deal with root rot as well.

Temperatures also play a role in bud drop. If it isn't cool enough at night (around 50 degrees) it interferes with bud formation. Be sure your gardenia is getting full sun if you have it indoors; partial sun outside.

-- Contributed by: Pat Hebert

It is best to wait until spring to repot your gardenia and then, only if it is very root bound. They actually like to be a little root bound and do better that way.

If it truly needs repotting, just carefully remove it from the pot, gently loosening the roots if needed. Be careful not to damage them. Then place it in a pot that is one size bigger. Do not plant it any deeper than it was originally. Use well drained, acidic soil and follow the instructions in the article above for planting a gardenia.

Have you tested the acidity of the soil? Gardenias like acidic soil so you may want to consider adding a bit of vinegar to the water. Some even add pickle juice!

Keep in mind also that when gardenias are in full bloom, they will not have as dense of foliage.

Rosy,

Keep in mind that most gardenias do not bloom all year round. It may not be time for it to bloom right now.

Also, if you have been having problems with pests, it may need some time to recover. You should also be sure that it has proper drainage and enough warmth.

I recently moved on a day that was really hot, my Gardenia spent 5hrs in the car (no AC)in full sun. By the time I arrived at my location a lot of leaves had turned black and since then all have turned and died. Several days before I moved I sprayed an insecticide over it to get rid of aphids - I'm thinking the combination....? I have cut the branches back somewhat and can see indications of green under the bark of the branches but I haven't seen any new green shoots for a month. Please help.

-- Contributed by: Harriet

Chase,

If you've only had your gardenia for about three weeks, it probably didn't need to be repotted. Gardenias actually like to be a bit root bound. Right now it is probably just in shock.

Give it some time to recover. Don't let it get dry but also don't allow it to be soggy. Be sure it has adequate sunlight and humidity. More information can be found in the articles Gardenias Problems and Growing Gardenias.

Malcolm,

I'm so sorry about your wife. I'm sure she would appreciate your care for her gardenia. The fly she was referring to is likely whiteflies. I always recommend spraying gardenias with a neem spray to control the whiteflies (or any other insect issues).

Also, be sure your gardenia gets enough humidity. This is essential for gardenias to bloom and be healthy. Do not mist the plant because this can cause a fungal growth. Instead, put a tray of pebbles under the pot and keep it filled with water.

For more information, read Gardenias Problems.

-- Contributed by: Kathleen Roberts

Rita,

You may need to first give your gardenia some time to get used to its new environment. Often gardenias will suffer from shock if they have been moved or transplanted.

If you have just purchased it, it most likely has some sort of time-released fertilizer in the soil already. You may need to provide more warmth; cold temperatures will often cause yellow leaves. Also, be sure your plant is getting proper drainage.

-- Contributed by: Kathleen Roberts

Kitty,

Yellow leaves can be caused by poor drainage or a lack of nutrients. A few yellow leaves are normal, but many indicate a deficiency of some sort. If you are sure that the drainage is adequate, try adding a nitrogen fertilizer.

Another possibility is that your gardenia is too root bound. Oddly, they do seem to prefer being slightly root bound, however if they are too root bound you may see yellow leaves.

Root rot may also be an issue. If you do have poor drainage the roots will rot away. You can check out the roots by carefully removing the plant from the pot and inspecting the roots. If root rot is too severe, you are not likely to be able to save the plant. If it is only slight, you can remove the dead parts and pot into better soil that drains well (perhaps mixed with a bit of peat moss).

-- Contributed by: Kathleen Roberts

Todd,

Have you tried giving your gardenia some fertilizer? It may be lacking in nutrients if it is potted. If you can't find one specifically for gardenias, you can use one designed for azaleas.

Another trick is to pour pickle juice or vinegar into your plant's soil about once a month. The recommended amount is one cup of juice or vinegar to a gallon of water.

Ok. I live in Utah and I have a gardenia, I've had it about three weeks but I don't know what species it is. But my leaves are droopy, I just repotted the plant because the pot I put it in was too small. What should I do.

-- Contributed by: Chase

Gina,

When repotting a gardenia,you should only go about one size up in pots at a time. Too large of a pot will not help your gardenia to thrive. Usually it is best to wait until after your gardenia has bloomed before repotting.

If your buds won't open, it may be a problem with the pH of your soil. Gardenias like slightly acidic soil. Try a soil test kit to be sure of your soil's pH. Also be sure the soil is well drained and keep you gardenia warm enough. Cool temperatures can keep it from blooming.

Gardenias actually seem to prefer being slightly rootbound. They do not like having their roots disturbed and only need repotting every couple of years.

I was given a gardenia for my b-day. it was in a small pot. I transplanted it to a very large pot because my sister said it was root locked and thats why the buds weren't opening up. Its been 2 weeks and the buds are still closed. Am I doing something wrong?

-- Contributed by: Gina Crawford

Mike,

Yes, you should definitely continue as you are doing. Another method is very similar: Put pebbles in your pie plate so the roots do not sit in the water. In this way, your gardenia will get needed humidity without the chance for root rot or leaf fungus (which can occur when you water directly on top; the leaves get wet and then fungal growth occurs.)

You're doing great! Keep up the good work.

Jasmyne,

Both of these varieties will prefer partial shade. The only time you should give a gardenia full sun is if it is kept indoors.

I am in zone 11, which is very hot as well, and my gardenias are under an awning on my deck. They get some sun but it isn't over done. I would recommend something similar for your gardenias.

George,

Brown tips on the leaves of your gardenia are typically caused by over or under watering. Another possibility is that too much salt has ac...ulated in the soil. In this case, you'll need to leach the soil to remove all the excess minerals.

-- Contributed by: Kathleen Roberts

Annuals only last one season from seed to flower. Often they will reseed themselves.

Perennials are plants that come back each year. With these definitions, I would have to say that gardenias are perennials. While gardenias are often grown in pots, they are actually a shrub. They can last for several years depending on the climate they are kept in as well as the care you give them.

Sekyo, are you pruning your gardenia? If so, you may be pruning it at the wrong time and actually pruning off the blooms. Generally it is best to wait until after your gardenia has bloomed to prune. If it has not bloomed, just wait to prune it. It isn't essential to prune it unless it is getting too big and out of hand.

Another possible problem is nutrition. Are you fertilizing your gardenia? You can try a fertilizer that is designed for azaleas and provide it in the way described above in the article. You need to be sure the pH of the soil is around 5.0 to 5.5 also, in order to keep your gardenia happy.

-- Contributed by: Kathleen Roberts

Marie, misting your gardenias is a very bad idea. It can cause fungus to grow on the leaves, which I suspect is the problem in your case. Because gardenias like humidity, it is best to place the pot in a tray of pebbles filled with water. The water will evaporate, providing needed humidity, without getting the leaves wet.

Gardenias also prefer partial shade to full sun depending on where you keep it and your climate. I have a potted gardenia that is on my patio under an awning in a very warm climate. It gets some sun but not full sun. However, if yours is indoors, it will prefer full sun.

It isn't a surprise that the leaves have turned yellow when you moved your gardenia. This can be the result of being stressed and may resolve itself.

If it does not, yellow leaves can also be caused by poor drainage, cold temperatures and incorrect pH. Also, old leaves will commonly turn yellow as well.

-- Contributed by: Kathleen Roberts

Bud drop can be cause by various things. You can start by testing the pH of your soil. Gardenias prefer to have a pH 4.5 to 5.5. You'll also want to be sure you're providing enough humidity via a pebble filed tray of water, not misting which can cause fungal growth.

Other causes of bud drop include too much or too little watering and temperature fluctuations. Try not to move your gardenias around; this will stress them and cause them to drop their buds as well.

I live in GA. I bought a gardenia and my first mistake was planting in full sun light (store planting suggestion said to do this), the leaves would turn yellow and fall off but everytime I fertilized with acidic food it would grow green leaves and get full for a month and then start the yellow leaves again. I moved the plant so it would get morning shade and afternoon sun, fertilized with a three month slow release acidic plant food and its growing wonderfully.

Ginger,

Usually when leaves drop from a gardenia, it's because it is too dry. It may be due to dry soil or due to dry air.

Soil should be kept moist, but not soggy. You don't want to cause root-rot.

Gardenias also like humidity. This does not mean to mist your gardenia. Instead, consider a humidifier or a shallow tray that the pot can be placed in. This tray should be filled with pebbles and then with water, as described in the article above. The water will evaporate, giving your plant needed humidity.

It is also possible that moving it has caused the leaves to fall off. If it has suddenly had a change in it's light or temperature conditions, it will react by dropping it's leaves. If you still see some green on it, keep the soil damp and give it some time to recover. Just be sure it has full sun, as all gardenias need.

Often black spots are actually a fungus called sooty mold that grows on the sticky excretions (called honeydew) of the white fly. Your solution, therefore, would be to control the white flies.

Spray your gardenia with insecticidal soap to wash off the sooty mold. Then continue to treat it every two weeks with a horticultural oil to keep the white flies under control

Hi Rich,

To test for pH, you can purchase a test kit and any garden center. They have easy directions and you will have no problem using one.

Alternately, you can contact your local Extension Service. They have experts who can test your soil for a small fee. They can also advise you on the best way to improve your soil if it is lacking in any way.

Hi Rebecca,

This may be perfectly normal depending on the type of gardenia you have. Some gardenias get very large. Some only bloom once per year. You may just need to wait until it is ready to bloom again.

Hi Ruth, The black you see on the plant is probably sooty mold. It is caused by sap sucking insects that have probably invaded your plant. Pests can include aphids, scale and mealy bugs, which are common to the gardenia. Try spraying the entire plant, including the undersides of the leaves with a soap solution or you can use a horticultural oil, like neem. This should get rid of the pests. Then wipe the leaves clean.

This will give you an idea of whether a group of gardenias will be too much for you, or your family members, before you plant them. I would also consider whether you have a regular breeze to help diffuse the scent in your yard.

-- Contributed by: Charlotte Gerber

Hi Help Save My Plant, It sounds as if your plant has some pests affecting it. I would advise trying a soap spray on the tops, underside and stems of the plant. This will get rid of most pests that affect gardenias. Alternatively you could use horticultural oil in the same manner. I would also advise checking the soil pH and be careful to keep the plant soil moist, not wet.

Hi Jo Ann, Depending upon the variety, a gardenia may bloom once or several times each year. Your plant should be happy in the window as long as it receives 6-8 hours of full sunlight each day and is kept moist.

-- Contributed by: Charlotte Gerber

Hi Ohio Mary, I would place more soil around the plant to make it stable. It is probably okay in the pot you have it in. Gardenias can be pruned to the right size for the pot it is in. (However, only prune right after the plant is done blooming).

A favourite aunt of mine recently surprised me with a Gardenia plant, and I am just ecstatic about the perfumed flora. But, unfortunately, the plant is plagued with every possible problem I can think of! First the bud dropping, then fungal leaves, now I am seeing a foamy secretion around the leaves. Can anyone tell me if this foamy substance is good or bad for the plant? And, if it is bad, how I can get rid of it? Canada-Zee

I received a gardinia plant from a friend last summer and after it finished blooming, every leaf dropped. I thought it was dead but I put it outside last spring and the leaves came back and it is beautiful now! Do you think it will bloom again? Since I live in southern Ohio, I have brought it back inside next to an east window. Thanks, Jo

Charlotte, Thanks so much for your response. Only thing I'm not sure about is the woody roots exposed above the soil in the middle of the pot at soil level. Do I cover them with soil? If you move it, it can rock somewhat. Would it be okay to add dirt? OHIO MARY

Hi Mary,

It is too late to prune the plant this year, unless you don't care whether you have blooms next year or not.
Gardenias need to be kept moist, so keep it well watered, but not soaking wet.
Gardenias have to be kept in a warm, moist environment, so keep it away from heaters in your home.
Gardenias need 6-8 hours of direct sunlight each day.
Buy a soil pH tester in your local gardening center (they're inexpensive and helpful with gardenias). The soil pH should be 4.5 - 5.5 ideally.
Buy some soil acidifier to have on hand- occasionally these plants need a pick-up when they have been stressed (yours might need it because you've changed the environment recently).

Good luck! Gardenias can do well both indoors and out when the right balance of light, soil pH and moisture are met.

Help...I have acquired a gardenia plant and desparatly want to keep it growing as it was my mother in law 92 who passed away in Feb but I was just given the plant in October. To the family it is very sentimental. It is a potted plant,pot is aprox 11" tall. Plant is 2 1/2 to 3 ft wide and 2 ft tall above pot. It always bloomed for her and was beautiful. I don't know when it bloomed last so I don't know when to prune it or the best way. The leaves are light green not really dropping off, but some are crispy and I just found maybe 2-4 leaves with a little hole in them. At the base of the plant the roots are woody and exposed in the center, don't know if I should cover with dirt or repot. I have brought it in due to cooler night temperatures here in northwest ohio. I am not sure how to check/know ph of soil, have read different opionions on fertilizing. I found one bug on top of plant and captured it, it was a brown aphid, could only find one. No signs of babies or any fungus. I picked off any leaves that looked bad hoping that would help existing leaves get more enery. My guess is this summer plant was not watered regularly and was set in the grass for a period. When I got it two days ago it was soaked so I am letting it dry out. Just would like to know what i should do to start taking care of this beloved Gardenia, any help would be appreciated.

Hi Darla, If the leaves are turning yellow and dropping off it can be due to three things:

Cold temperatures - below 60 degrees Fahrenheit
Poor drainage - they don't like to be constantly wet
Wrong soil pH - add soil acidifier as necessary to maintain a 5.0 to 6.0 pH level

I would also check for any signs of pests on the plant that may be causing problems too.

Hi Debbie, There are three things to check when your blooms won't open:

Soil pH - 5.0-6.0
Temperature - above 60
Proper drainage - these plants hate "wet feet"

If any of these things is outside of the norm for these fussy plants, the blooms won't open.

Hi Jim, The best time to prune a gardenia is right after it has finished blooming. Be sure whether your plant variety blooms once or twice before pruning. The new blooms form on the stems, so pruning late could mean no blooms next year.

-- Contributed by: Charlotte Gerber

Hi Kimberly, The white growth is probably mealy bugs. It can be treated with horticultural oil or a soap solution- simply spray all of the areas, top and bottom sides, of the plant where you see these white clusters.

In the winter months you should bring your plants indoors. They need to be in a warm room (around 70 degrees constantly) that is also humid. Use a humidifier if necessary. The plants need to be kept moist and have 6-8 hours of direct sunlight each day while indoors.

Hi Elaine, The soapy water would have been used to treat spider mites, which can be detrimental to the plant. Depending on the current condition of the plant (hopefully it still has leaves), I would recommend the following:

Make sure the plant has adequate moisture - don't let it sit in water. The soil should be moist to the touch, not soaking wet.
Make sure it gets 6-8 hours of full sun per day.
Check for any other pests that may have infected the plant - aphids, scale or perhaps more spider mites. Sucking insects, such as those just mentioned, can be treated by spraying the plant with a horticultural oil or using a systemic chemical like Orthene.
Give it a boost with a soil acidifier (follow the directions exactly).

-- Contributed by: Charlotte Gerber

Hi Mindy, The gardenia needs 6-8 hours of full sun per day. Secondly, the plant needs to be well drained- moist but not sitting in water. It also needs to be in a warm room if indoors, not in an air conditioned room. Finally, I suggest using a soil acidifier (carefully follow the directions). These suggestions should help you to bring the plant around!

Hi Lois, Gardenias need 6-8 hours of full sunlight each day. They need to be kept moist, but not soaking wet all of the time- don't let them dry completely out. Since it is the end of the blooming season, you can stop adding the soil acidifier- it might be too much of a good thing. When kept indoors, they need to be in a warm, humid area of the home- 70 degrees or slightly higher is best- keep them out of any air-conditioned room as it dries them out.

Hi Christina, You can use clean shears to cut your gardenia blooms, the length depends on what you desire. In terms of angle, that isn't necessary unless you are pruning the plant into a particular shape. Pruning needs to be done right after the plant stops blooming for the season or you'll risk cutting off next year's buds.

Prune the plants shortly after they are done blooming. Use sharp pruning shears to create a shape that you desire for next year. Gardenia's don't need to be pruned every year though - so do so only when your plant needs to be shaped.

Hi Mary, Without seeing your plants, I'm not sure if you're dealing with mold or bugs. Mealy bugs look like little cotton ball masses and can be treated with soap spray or horticultural oil. Use mulch around the bottom of your plant, but don't have it so thick that it touches the bottom leaves of the plant.

Hi Anita, Bloom drop can occur when the temperature isn't consistently warm, poor drainage, lack of humidity and not enough sunlight.

Hi Lynda, It is true that the Gardenia is an acid loving plant. You can buy plant food in your local nursery or garden retail center - look for food for blueberry or azalea plants if you can't seem to locate gardenia food specifically. You can repot a gardenia, but it must be done after it has finished blooming for the year. It is a good idea to have marbles or pebbles in the water dish beneath the pot to keep your plants from soaking in water. The temperature for your plant should be around 70 or higher since they are a warm climate plant. Consider putting the plants in an area that does not ever have cold air around or blowing directly on it.

I just purchased a Gardenia Plant for indoors. I have one room in the house that gets plenty of sun light, In fact that is where all my plants grow(and beautifully I might add). I seem to be loosing a lot of leaves lately on the gardenia but yet it is nice and green and getting new shoots. I've read it needs an acid soil containing peat moss and compost. Should I get those soils and transplant my Gardenia. It also claims I should put stones in the water tray that the plant sits in but never let the water remain in there. Is that correct? Also, "Heavy feeding", do they have special foods for Gardenia, or any plant food. I also buy and use "Jobe's Fertilizer Spikes" for my other plants, will they be alright for the Gardenia plant as well? I appreciate any other suggestions you might give me. I also understand that it says humidity, but I have COPD and need air conditioning. Will this effect my plant. I have it as far away from the air conditioner, and as I said it gets plenty of light. I live in Pennyslvania, in the city. I cannot plant it outside. I would really like to hear from you, and have a very good, and Blessed day.

Hi Patricia, I agree with 2spots; try a soil acidifier, if you aren't already doing this. Yellow leaves can also be caused by poor drainage. Check to make sure your plants aren't sitting in water in their pots- if so, raise the pots up on marbles or pebbles to ensure proper drainage. Finally, if it is below 60 degrees overnight, bring the plants in. They don't like cold weather.

Hi Shahin, It sounds as if your soil is too dry; this will cause the condition you mention. The only way to rectify it is to water your plants and keep them moist, but not soaking wet. Gardenias don't like to have wet feet. You can also try adding a little soil acidifier to help them along.

For yellow leaves you need to acidify the soil. Look for a product called Ironite or ask your local garden store for a product to acidify the soil. Also, fertilize with Azalea/Rhododendron specific type.

Hi Sheila, Gardenias are temperamental, so re-potting them soon after you receive them can put them into shock. I'd wait a while before I re-pot it, after all, you don't want it to get too large since it is a bonsai. I don't know what type of pot you have, but you could try watering it from the bottom and then after it has soaked for a while, take it out of the water and then place it on a saucer filled with marbles. This will allow it to drain properly (they don't like wet feet).

Hi Diego, There are several things that you can check for yellowing of the leaves. First, poor drainage can cause this problem. Make sure that your plants are in well-drained soil. If they are in pots, put the pots up on rocks or marbles in their dishes so they drain thoroughly. These plants also need 6-8 full hours of sun every day. Finally, add a little MirAcid to the soil (the pH of the soil should be around 5.0 to 5.5).

Hi Maryanne, There are several things to check. First, gardenias don't like water on their leaves, carefully water the plant close to the bottom of the plant.

Finally, check the undersides of the leaves to see if there are any pests.

Hi Jan, I'm not sure if you meant the blooms came off this year or last year. If you do have a few blooms this year that won't open and are hard, the first thing you should check is the soil pH. It should be between 5 and 6. Next, make sure the plant is draining properly- gardenias don't like having wet feet. Finally, consider the climate where you live. Gardenias like a warm, humid, constant temperature. Cold overnight temperatures, especially if they are kept outdoors, may be the cause of the bloom problems. Check out our article, Gardenias Problems for more tips on gardenia care.

Hi Jane, The best time to transplant a gardenia is after it has completed blooming, otherwise you'll lose the buds. If you just bought the gardenia, it may not need to be transplanted to another pot yet, but if you are putting it in the ground, you could do it right away. As for the pot size, make sure it is a few inches bigger around than the previous pot; gardenias don't like to be root bound.

The gardenia should only be trimmed back right after it buds in the summer or when it has completed blooming for the season (some gardenias bloom more than once). If you cut the plant back after the buds have set at the end of the growing season, you won't have any flowers the next year.

Hi Mitzi, First, check the plant for any sign of pests (under the leaves, look for bugs coming out of the soil when you water it at the base of the plant and on the stems). If there are no signs of pests, try using some MirAcid the next time you water your plant, being sure to carefully follow the instructions. Also, be sure that your plant is getting enough water, especially as warm weather approaches.

I have a Gardenia purchased in Texas March, 2007. It had 4 open blooms and 7 unopened buds. The wind blew the buds off. I brought it home to Missouri and it is a healty looking plant with new leaves but until now, it has not bloomed again. At present, it has several unopened buds again. I try not to overwater, have had it inside during the winter but have it outside now in partial shade in a pot. Where do I go from here? I have a brown thumb usually but I really do want to keep the plant healthy and alive. Thank you

Hi Mary, Gardenias are temperamental. If the blooms are important to you, wait to re-pot the plant until after the blooms have died off. Otherwise, you can re-pot it anytime.

Hi Liz, The following tips should have your gardenia back on the road to recovery, assuming there aren't any pests involved:

Gardenias need consistent moisture- not too wet and not too dry- somewhere in the middle. Be sure your plants have proper drainage whether they are in a pot or in the ground. Next, your soil may need some acidifying as your plant may be needing iron or magnesium. You can do this by adding an acidifier (such as Mir-Acid) directly to the soil or by using a foliage spray. Carefully follow the package directions to avoid further damage to your plants. The temperature may also have something to do with the yellowing leaves. The soil temperature needs to be around 70 degrees- anything below this can induce yellowing.

Hi Mo, You can prune your gardenia to make it look fuller and healthier, but it usually doesn't have to be done every year. Prune it right after the last of the blooms have fallen off at the end of the summer/early fall before the new buds have formed (otherwise you won't have any blooms next year).

Hi Barbara, I don't think the Miracle Grow did the harm to your plant; these plants can be fertilized in the spring if the product is used according to directions. MirAcid is a good fertilizer for this acid-loving plant. You didn't mention if the plants were indoors or out. If they are indoors, the room they are in may not be cool enough or humid enough. They should be moved outdoors as soon as possible- they should recover then. If the plants are outdoors, make sure they are in well-drained soil and have plenty of sunlight. I would also look at the leaves to make sure there are no bug infestations.

Hi Julie, I've heard of some people having success with dividing their gardenias, but I've also heard that this killed the plant too. Most people propagate their gardenias by layering or by cutting shoots from the plant, dipping them in rooting hormone and then allowing at least a 1 inch root to form before planting.

Hello Nancy, You can repot your gardenias anytime, however if they are in bloom and and you don't want them to drop, wait until the bloom cycle has ended. Gardenias do not like to be root bound and they will not thrive this way.

Hi Joe, You need not remove the spent blossoms to help the new buds along. Removing them would primarily be for aesthetic reasons.

Hi Kathi, The best time to prune your gardenia is after the blooms are fading at the end of the summer. If your gardenia blooms more than once, make sure that it is at the end of the last blooming cycle. The new buds will set in the fall. Do not prune your plant after October 1, even if you live in the warmer southern states of the U.S. Pruning a gardenia is only necessary to keep it at the size and shape you desire. Most plants don't need to be pruned every year.

To prune your plant, begin with the sharpest pruning shears you can find. This will help you to avoid crushed or jagged edges which invite pests and disease. You may trim back both the green and brown wood since buds will appear on both. Try not to trim back shorter than 4-6 inches from the base of the plant.

-- Contributed by: Charlotte Gerber

Hi Peter, Gardenias need the right amount of sunlight, high humidity, temperature and a perfect balance between the soil and nutrients. If any of these essential things are missing, it could explain why your plant is doing poorly.

The gardenia needs at least a half day of direct sun light. Try plant-grow lights if this is one of the suspected problems. Next, humidity is necessary to a healthy gardenia. To create this type of environment try using a humidifier in the same room as the plants are in and put the plants on trays of water with pebbles in the bottom (you don't want to soak the bottom of the plant). Cooler temperatures are preferable, as close to 55 degrees as you can make it is best. Finally, use a fertilizer designed for acid-loving plants and carefully follow the directions. Hopefully, this will keep your plants a little happier until you place them outdoors again.

Hi,

We have had the Gardenia inside from Jan-March.We then put it back in the house however its still wiltering ... Can you help

-- Contributed by: Peter Slevin

Hi Marge, There are several things that could be causing the brown leaves. First, be sure to make sure your gardenia is getting enough moisture (especially if it is indoors). Always water this plant from the bottom up. Second, gardenias need a soil pH of 5 to 5.5. Finally, spider mites could be causing the problem. To find out if this is the case, take a piece of white paper and place it under a branch of the plant, then gently tap the branch. Fold the paper in half and rub the sides together. Open the paper- if you see any brownish smudges, your plant has spider mites. Spider mites can be treated with Neem; follow the directions carefully when using this to treat your plants.

Altra, this black mold is called sooty mold. This indicates that you probably have a problem with aphids. Try using a horticultural oil to control the aphids. Follow the directions very carefully. Once the aphids are gone, you should see the sooty mold disappear as well.

-- Contributed by: Kathleen Roberts

Kay, gardenias do best in a potting soil designed just for them, or one made for azaleas. Try mixing peat moss into the soil to aid in proper drainage. If your gardenia isn't draining well, this may be the cause of your yellow leaves.

Keep in mind that yellowing is normal for older leaves. They will drop and be replaced with new leaves.

-- Contributed by: Kathleen Roberts

Mary, Spanish moss is not harmful at all. It is an "air plant" so it does not hurt the plant it is on. In some cases it may block sunlight which can slow the growth of some plants. If you want to, you can pull it out of the trees and shrubs. However, many people enjoy the look that Spanish moss adds to the landscape.

Jean, you will want to provide partial shade if your gardenias are outside. They thrive in zones 9 and 10 so just be sure that they don't get dried out and they should do just great.

-- Contributed by: Kathleen Roberts

Seta, first I recommend that you give your indoor gardenias full sun if at all possible. This is important for them to thrive in your house. They may also need more humidity. Ty placing the pots in a tray filled with pebbles and water. Add more water as it evaporates.

Usually when a gardenia looses its buds or gets black tipped leaves, this is due to a change in watering or temperatures. Gardenias are a bit finicky and don't like changes very much.

-- Contributed by: Kathleen Roberts

Kathy,are the yellow leaves all over the plant or is it just the older leaves? If it is just on the outer leaves, they may just be old leaves that are ready to drop. This is nothing to worry about.

If it is widespread and can be seen on new leaves this may be a problem called iron chlorosis. This is caused by not enough iron or iron that cannot be used by the plant. Try a fertilizer for azaleas or one with a liquid or chelated iron. You can also add sulfur to your soil to make the iron in it more easily used.

-- Contributed by: Kathleen Roberts

Norma, you can re-pot your gardenia. If you do, choose a pot that is one size bigger than the current one. As is mentioned in the article, gardenias prefer an acidic, well-drained soil. Try a potting mix designed for azaleas if you can't find one specifically for gardenias.

I can't say for sure if your gardenia will do well outdoors because I don't know your climate. Your best bet is to read the section above on outdoor planting and determine you garden zone. If you are in zones 9 or 10 it will probably do just fine outside.

-- Contributed by: Kathleen Roberts

Judy, bud drop can be caused by many things. Lack of humidity, too much or too little water, incorrect lighting and temperatures and, as you mentioned, relocating your plant, can all cause bud drop.

The white stuff is probably powdery mildew. This can be controlled with a fungicide.

Jadey, it is possible that your gardenia isn't getting enough light. It may also need to be fertilized. Both of these issues can contribute to pale foliage.

-- Contributed by: Kathleen Roberts

Sarah, this sounds like sooty mold, which ultimately is cause by aphids. Aphids excrete honeydew which is what the mold grows on. To control the mold, you must control the aphids.

One non-toxic way to control aphids is with beneficial insects. Ants are actually helpful in controlling aphids and may already be in your garden. You can also spray your gardenias with a horticultural oil. Follow the directions carefully--more does not mean better. Once the aphid problem is under control the sooty mold will go away.

-- Contributed by: Kathleen Roberts

June, it may have been a mistake to cut the roots as this will not encourage new roots, but it will reduce the roots that the plants need.

Also, consider the size pot you put your gardenia in. Generally it is recommended that you re-pot in the next bigger pot. If the pot you used to re-pot was too big, you may have a problem with root-rot. You can check this by gently taking your gardenia out of it's pot and examining the roots. If this is the case, you will likely need to replace your gardenia.

-- Contributed by: Kathleen Roberts

Mary, are you providing enough moisture and regular fertilizing? Have there been any changes in it's care or environment?

Keep in mind that, just like animals, plants die when they get old. It is possible that your gardenia has just lived it's life and is done.

-- Contributed by: Kathleen Roberts

Karen, Anne and Christine: The best time to prune your gardenia is right after it has stopped blooming. This will allow it time to form new growth which is where the next year's blossoms will form.

One rule of thumb when pruning a gardenia, or anything else, is to avoid cutting away more than one third of the plant. Concentrate on cutting old growth on a gardenia but do not remove more than a third of the entire plant. For a very overgrown plant this may mean that it takes a few years to get it the size you desire, but it will assure that your plant remains healthy.

I bought a dwarf gardenia from a local nursery when it had many blooms and looked quite hopeful. The first few months my blooms did open, but in the year and half since then I've struggled with yellow leaves that would drop and no buds at all. I realized in the last 6 months or so that mixing in used coffee grounds to the soil on a semi-regular basis cured the yellowing leaf problem. I add the coffee grounds from a pot of coffee about once a month, and supplement with extremely fine grounds I used when making Turkish coffee 2-3 times a month. This followed by a reasonable watering will help soak the coffee in. I live in Texas and right now (Feb) it's not flowering time, so I guess I shall see how the floweing process fares this fall/winter. My plant is potted and stays outside for the majority of the year, except when we get freezes in the winter. Good luck to all!

Jan, it is possible that brown leaf margins are due to a lack of humidity. Misting is usually not a good idea because moisture on the leaves can cause fungal problems. However, placing your plant in a pebble filled try of water will allow it to get needed humidity (as described above in the article). Also, water your plant thoroughly when the top of the soil is dry, but water at the base, not over the top of the plant.

If this does not solve your problem, it could be a nutrient deficiency.

Hope that helps.

You are correct Jaime, gardenias prefer acidic soil. However, it is a good idea to test your soil before you try to make it more acidic.

Pine needles are helpful for making soil acidic, but I don't know how easy they would be for you to get in Peru. Composted pine bark may also do the trick.

The addition of sulpher or aluminum sulphate will help but you must follow the directions carefully so you do not over do it. You will also need to re-apply frequently.

I am not sure how to change your water. Some people suggest using vinegar or lemon juice. I would just use bottled water or rain water collected in a rain barrel.

I hope these suggestions are helpful to you.

Marg, this is hard to answer without knowing a bit more about your situation. Is your gardenia in your home or outside? What temperatures are you experiencing?

Your problem may be due to over/under watering, incorrect amounts of fertilizer or sunlight or even too warm of temperatures at night.

Most commonly, bud drop is due to a lack of humidity or water that is overly alkaline. Instead of cutting off the buds, try to make some adjustments in the care of your gardenia and see if that helps.

Fran, it is best to prune gardenias after they have finished blooming. New flowers form on the growth from the previous year so cutting back now will prevent flowers in the summer.

Make sure your gardenia gets enough humidity now that it is inside. The best way to do this is to place the pot in a tray of pebbles that is filled with water. Also, be sure you do not have it under a heating vent or near a fireplace.

Give it plenty of light and give it some tome to recover from being moved. They tend to dislike being moved around but it should recover if you baby it a bit.

Dawn, I think your location sounds fine. Consider getting a fertilizer that is made for azaleas because it will do a better job of meeting your gardenia's nutritional needs.

Although I keep getting what I think are flower buds, they never bloom. I have yet to produce any flowers other than the ones that were on it when I purchased it. My kitchen window, although bright, is a northwestern view (our house is on a diagonal to the sun). Do you think that my plant does not get enough direct sunlight, or do you think it is too close to my other plants?

Stanrena, it sounds like you are on the right track. Just make sure it is getting full sun now that you have it indoors.

Robbi, your gardenia needs fertilizer. Consider pruning some of the older branches as well to encourage blossoms.

My gardenia, when first received as a gift, dropped all of its buds. Now I have brought it indoors, I already had to cut one branch, and am seeing some yellow leaves. I've just fertilized it with miracid and will keep it from sitting in water. Am I doing o.k?

-- Contributed by: stanrena

The leaves on my gardenia plant are turning yellow. I also have a lot of buds on another gardenia plant that just open up to be more leaves. What can I do to prevent this?

Shawn, are seeing webs, or actual spiders? If you are seeing webs you may have a problem with spider mites. Treatment of this depends on if your plant is inside or outside.

Usually outside plants have the advantage of predators to eat the mites. Blasting your gardenia with a hose every day until they are under control will help a great deal.

Indoor plants will need to be treated. You can find commercial preparations at your local garden center. Neem is a popular choice.

Sally, you may just need to add some fertilizer. Try a fertilizer designed for azaleas and see if that helps. Yellow leaves usually indicate a nutrient deficiency--specifically, nitrogen. Another tip that I have read, but not tried, is to add coffee grounds into the soil each week. Hope that helps.

Please I need help with the Gardenia...My question was that My Gardenia's are planted outside, in the sun in Wilmington NC, some of the leaves are turning yellow...Is this normal for this time of year?

Velma, this sounds like a mold problem to me. Commonly, sooty mold grows on the excretions of insects that feed on the leaves of your gardenias. Your only option, if this is the case, is to wash the leaves with soapy water.

This could also be caused by a lack of sunlight or inadequate ventilation (maybe too close to the house for air flow). Either way, this in itself isn't harmful to your plants. However, it doesn't look very nice and its cause can be harmful for the plants.

The sticky substance you describe sounds like the secretions of white flies. This is most likely what is causing the mold. The easiest treatment is to spray your gardenia with an insecticide. Once the insects are eliminated, your mold will go away as well. Be sure though that the insect problem is taken care of before you bring your plants indoors.

Hope this helps.

Sandra, I don't think it is a good idea to try to overwinter a gardenia in Michigan. If you can bring it indoors and place it in a bright sunny area it will do better, but it will need to be maintained over the winter.

Do you have someone who looks in on your plants while you are away? If not, you may have no choice but to leave it outside. If this is the case, you will need to make sure it is really protected and hope for the best.

Thank you for your question.

Theresa, you don't mention if your potted plants are indoors or outside but since you mention one in the ground, I will assume they are all out doors. If that is the case it should rule out a lack of humidity which would normally be my first guess.

Is the soil acidic enough? Are you letting the soil dry out too much? Depending on where you live, your plant may be winding down for the winter, in which case you can expect it to bounce back in the spring.

Hope that helps.

My gardenia bush has black on the leaves and stems. On the stems when you rub them black specks come off. I live in Indiana and leave it out in the summer. I am getting ready to bring it in and would like to know what to do about the black leaves and stems. The leaves also have sticky substance on them and drops to the floor. thank you

Gina, if it is getting cold you may need to bring them indoors if you are able.

Teresa, it is possible that if the area is well protected it will be ok. However, you will be taking a risk. If it was me, I would bring it inside.

I live in phoenix and wonder what the chances are of having a gardenia thrive in a southern exposure entryway that is protected on both sides by walls. I have put it in a pot with sufficient watering cycle. Is this hopeless?

I live in Central California and have two outdoor gardenias. Both plants are within 5 feet of eachother and the one who receives less light is whilting and the inner leaves are brown. Could my solution just be to relocate the plant? I don't wish to harm to plant since the temperatures are already starting to drop but should I keep both indoors for the winter?

-- Contributed by: Gina

Jackie, you can probably prune any time since blossoms form on new growth or old. The best time is right after your gardenia has finished blooming for the year. I would also say that you should avoid pruning in late fall so any new growth doesn't freeze.

Otherwise, pruning is only really necessary to keep the shrub at the size and shape that you want it to be, so only once every year or two is recommended..

Kristi, as long as your gardenia gets full sun it should be fine. If you want to move it to your porch, just keep a close eye on it to see how it reacts. If it appears to have problems you can move it, but it sounds like a good location to me.

Georgia, if you can put your plant in a protected area with lots of mulch it may survive but there is no guarantee. This can be a hard plant to grow in Missouri. If there is any way to bring it inside that will be your best bet.

Hi there. I'm wondering if it's ok to keep my potted star gardenias on our front porch, (which is shade cloth protected but fairly bright and airy), in the summer time? It's arid here, except for the day of/after rain in the summer. I don't have any rooms indoors that seem to be bright enough for it. Should I find another home for them?

-- Contributed by: Kristi in Australia

To overwinter your gardenia you will need to be sure its soil temperature stays around 60 degrees. It will also need full sun while it is indoors so I don't think the garage is a good place for it.

I'm guessing that it is potted since moving it is an option, so your best bet would be to bring it inside and keep it in a bright room.

Thank you for your question.

Have a gardenia bush growing south with partial shade. Since it is getting to be winter season here in Boise Idaho. Will the plant survive in the garage until spring time? Thank you for the answer.

Instead of watering your gardenia daily, try placing the pot in a pebble filled try that has water in it. This will allow your gardenia to get the humidity it needs without being overwatered.

When you do water, first push your finger down into the soil a bit. If it is moist you don't need to water it just yet. Wait until the top inch or so of soil is dry and then give your gardenia a nice drink.

Thank you for your question.

Hello: I just bought my 3-foot Gardenia from a local nursery. It looked so healthy and had couple of blooms. I've watering it daily and I even speak to my lovely plant. I noticed the leaves are turning yellow. What do you think is happening? Please let me know. Gardenia Lover, Marie

-- Contributed by: Marie

The best time to prune is in the summer after they have stopped blooming. It is also a good rule of thumb to not remove more than 1/3 of the branches of your gardenia. Too much pruning can damage the plant resulting in fewer flowers the following year.

LoveToKnow, We have several grandenia plants on our property. Some are near the house and under the window. I need to prun or cut back as much as 18 inches. Will this harm the plants and if not what time of the year is best. I live in Georgia, zip 31909. Thank you for your help. Jim Mixon please respond to my email address

Debbie, there may be several reasons for the lack of blooms on your gardenia. How long have you had it? Gardenias do not bloom continually. It may be in the non-blooming part of its cycle.

Has it been fertilized? Gardenias need fertilizer every three or four weeks.

Have you done any pruning? Flowers form on new growth so pruning old growth is important.

How about humidity? The biggest reason that gardenias stop blooming is that they don't get enough humidity. Try placing the pot in a gravel filled try that has water in the bottom of it. Add water as needed to assure that your gardenia gets enough humidity. I'm betting that this is your problem since it sounds like your gardenia is otherwise healthy.

Thanks for your question.

I have a beautiful gardenia growing in a pot. It is deep green and lots of growth happening. However!!! Though there was one open flower on it when I bought it, it has not bloomed once since!!! I live in Central California and have both an east and west patio exposure. Any suggestions?

Linda, this will depend on how the leaves look. If they are yellow with green veins, they may have a magnesium deficiency that can be remedied with two tablespoons of Epsom salts dissolved in your watering can. Apply this to the root area of your gardenia.

However, if the leaves are green with yellow veins this may indicate a iron deficiency that will be helped with the application of iron chelates. Check the labels at your garden center. EDDHA is the most effective form of iron chelates but it is a bit more pricey than other forms. Follow the dircetions on the package to apply.

If you aren't sure, try both remedies. On one day try the Epsom salts, the next day use the iron chelates. Water well after each application.

No Deb, I'm afraid your gardenia won't appreciate being planted outdoors in Ohio. However, you might consider putting it in a pot that can be outside in the summer and indoors the rest of the year. Hope that helps, and thank you for the question.

My Gardenia is getting a lot of yellow leaves. Wnat am I doing wrong?

-- Contributed by: Tess Andriatti

I bought a gardenia tree in a pot a couple months ago. It was doing fine, watering it weekly, and it's draining. The buds was coming up, then it turned brown and fell off before blooming. Now the leaves turn yellow. Yet, when I touch the ones that are still green, they feel dry - like it needs more water. I thought if it turned yellow, it meant it's getting too much water. I'm confused. What can I do?
