How to Plant Radish Seeds

Radish seeds do best in cool weather, just as radish's cousins, cabbage and broccoli. Select an area that gets at least six hours of sun each day. Seeds can be sown directly into the prepared ground but also do very well in containers. This is a great option if you don't have garden space.

Soil

It is important to have well-drained, rich, loose soil to plant your seeds. A pH of 5.8 to 6.8 is ideal. Soil should be tilled six to 18 inches deep, depending on the type of radish you are growing. Amended the soil, if necessary, with organic compost but avoid using fresh manure or fertilizers with a high nitrogen content. Nitrogen produces nice foliage but does little for the roots. Since the roots are your goal, you want them to develop well.

Make sure the soil is loose, with no rocks or other obstructions. This allows the roots to grow to their proper size without any barriers. Small spring radishes should be sown about a half inch deep and one inch apart. Larger or slow growing winter radishes need to be a bit deeper. Anywhere from three quarters of an inch up to an inch and a half is a good depth; check your seed package for specific planting depths for the variety you are growing.

Germination

Radish seeds usually germinate within a week. Once you see the seedling bursting through the surface of the soil, they should be thinned to about two inches apart. Winter radishes may need to be thinned to a six inch spacing. This will give your radishes enough room to grow without crowding.

After seedlings are thinned, they need to be mulched. Mulching helps keep the soil temperatures cool and also helps to retain moisture. It can also allow you to keep your winter radishes in the ground a bit longer if they aren't yet ready to harvest. A mild frost tends to improve the flavor of winter radishes. They will not survive a hard freeze however, so be sure to harvest them before this time. Harvest when roots are young, about an inch in diameter or less. Leaving them too long will result in hot, woody roots.

Learning how to plant radish seeds is a great project for beginners. Children will enjoy the quick progression from planting to harvest as many varieties are ready to pick about three weeks after planting. What a great way to get your kids outdoors!.

Simply put, if radish seeds are planted too close together they will crowd each other as they grow. Think of twin babies. When they are first born, they can share a crib. As they get older and grow, they start to get in each others way. Once they become adults, they are really sick of being so close all the time. One may just throw the other out of the bed leaving one twin a nice bed and the other sleeps on the floor.

That is over-simplifying for sure, but you get the idea.

Now, if seeds are planted at different times in the same spot, that makes a difference. By the time one has matured the other is just getting started. One is harvested about the time the other is getting big enough to need the extra space.

This is why every seed packet you buy has spacing requirements. You might be able to get away with spacing them a little closer together, but for the best results, plants need their own space.

Here is a good resource for you to use as you work on your project.

I am doing a science project about plant population I am trying to get information on how and why planting multiple seeds in the same space will affect the plant growth of radishes

Hi Anonymous, without knowing the dimensions of the pot, I could only guess. Radish seeds need to be planted about 1 inch apart.
