Pruning Gardenias

From LoveToKnow Garden

Pruning gardenias doesn’t take long, and with the proper tools you’ll have a nicely shaped shrub for your home or garden. Gardenias attract many gardeners for their glossy green foliage and white to creamy yellow, heavily scented flowers. There are many gardenia varieties to choose from, each with its own characteristics and preferences. They grow best in warm gardening zones or indoors in a sunny, bright window. While they can be fussy and experience problems, many people love growing gardenias and the satisfaction they bring.

Pruning Gardenias

Pruning gardenias is one of the most popular issues gardenia owners ask about. Many people understand the need to prune off unsightly growth, but are concerned that they’ll harm their gardenia plant. It’s actually easy to prune a gardenia.

Timing

Time your gardenia pruning so that you snip the plant after it finishes flowering. If you prune your gardenia too soon, you’ll end up cutting off the pretty blossoms. If you wait too long, you’ll end up cutting off next year’s flowers. For most gardening zones, the best time for gardenia pruning is right after the flower petals drop off. This usually happens during the summer or early fall months, depending upon the gardenia species and your particular growing zone.

Pruning Techniques for Gardenias

Before pruning gardenias, make sure your gardenias actually need a haircut. Take a look at the plant and note its overall shape. Is the appearance pleasing? You can let gardenias grow naturally or gently trim them into a neat, rounded shape. Most people prefer gardenia houseplants to look neat and shaped. Many allow outdoor gardenia shrubs to grow into a more natural form, with trims every few years to keep them below windowsill level or away from homes, telephone lines, or other items they need access too.

Pruning Tools

You can prune gardenias with a variety of hand tools, but experts recommend pruning gardenias with a bypass pruner. This gardening tool is a hand-held, heavy duty gardening shear with a special blade called a bypass blade. Bypass pruners work much like ordinary scissors. They make neat, clean cuts. If you’re shopping for pruners and the package doesn’t say whether or not they are bypass pruners, look for a pruner with two separate blades joined by a screw. They should open and close like a common pair of craft or sewing scissors. Another very common type of pruner is the anvil pruner. Anvil pruners work like their namesake, the blacksmiths’ anvil, by striking one blade against the other. They tend to crush more than snip, and while some plants benefit from this, gardenias do best with clean, clear cuts.

Outdoor gardenias, especially more mature plants, may have tough stems that require a nice, sharp bypass pruning shear. You may be able to get away with trimming gardenia houseplants and small shrubs with very sharp kitchen shears.

How to Prune

After examining your gardenia and ensuring that the time is right for pruning, simply snip the branches off that you want to prune. You don’t need to cut them at a special angle. Just be sure to leave the remaining branch at least five to six inches long to support new growth.

Any branches that appear to be dead may be safely trimmed off of the plant, no matter what time of year. To tell if the branch is dead, run your fingernail along the wood to remove the outer layer. If the under layer is green, there may be life yet in the branch; leave it alone. If the under layer is brown or brittle, it’s a safe bet that the branch is dead and can be removed..

It is best to prune right after blooming to assure flowers the next season.

Prune off all dead branches. Other branches ca be pruned as much as you want, as long as you leave at least five or six inches.

I have two Gardina bushes, one is about 5feet tall,which I need to cut shorter, covering window. How far down should I cut it? The other one is only two foot high and looks like it is dieing. I plan to prune both. Any suggestions?

Hi Tim,

I think Jeanne meant that you should leave a minimum of five to six inches. You can certainly leave them longer if you prefer.

It sounds like you are already doing a great job with your gardenias. I'd say, keep doing what you're doing because it's working.
