Growing Radishes in Containers and Pots

Don’t let limited space keep you from enjoying delicious home-grown radishes! No matter the size of your garden, we’ll show you how to produce a bountiful radish crop in containers all season long.

The Best Container Size for Radishes

The first thing to consider when growing radishes in a container is what kind of pot you’re going to use.

Radishes have a fairly small root system, so just about any ole container you have lying around will do. But if you’re looking to get technical, a good rule of thumb is to aim for a container that is roughly 288 cubic inches (4,719 cubic centimetres) in size.

Depending on the size of the pot you’re using, you can also put multiple radish plants in one container. Growing multiple radishes in one pot is a great way to increase yield while working with limited space. It’s typically suggested to space radish plants 1 - 2 feet (30 - 60 centimetres) away from each other. But for most varieties, you can get away with packing radishes in a little tighter than this.

The Best Type of Container for Radishes

Plastic pots, terracotta, and fabric grow bags all make fine containers for radishes. When choosing a pot to plant radishes in, the type of material it’s made out of doesn’t really matter. What does matter, however, is how well that material releases excess water.

Poor drainage is the number one killer of radishes grown in pots. If your radishes sit in standing water for too long, their roots will rot and the plants will likely wither away.

If you’re using a plastic container for growing radishes, it’s crucial there are 2 - 4 holes in the bottom to allow excess water to drain.

Terracotta pots, along with fabric grow bags, are a great container option for radishes because they are naturally porous. Most terracotta pots also come with a hole in the bottom for additional drainage.

If growing your radishes in grow bags, be sure to test how well they drain before planting. If water doesn’t leak through the bag quickly, you may want to add one or two holes to the bottom to keep the roots of your radish plant healthy and happy.

The Best Soil for Growing Radishes in Containers

Drainage also plays a key part in the type of soil you choose for radish containers.

Traditional soil, such as the type of dirt you can dig up in your backyard, is much too dense for radishes planted in pots. It will trap moisture in the container to the point where it can cause fungal issues for radishes as well as root rot.

Instead, opt for potting soil or soil specifically designated as safe for container gardening. Avoid all others.

Final Tips for Growing Radishes in Pots

Hopefully by now you’ve seen that growing radishes in pots is pretty easy so long as you have the right container and right soil.

The key, as stated before, is drainage. You will likely notice that radishes grown in containers are much thirstier than radishes grown in a traditional garden bed. Be sure to adjust your schedule to water more frequently.

Of course, the same rules apply to container grown radishes that apply to radishes grown in a traditional garden, such as the amount of sunlight they need and when to plant them. You can find that information (and more!) in our complete guide on growing radishes.

Happy planting!
