Spring varieties including Cherry Belle, April Cross, Purple Plum, and Red King are oftentimes round or elongated which are perfect for container gardening if you have a small to a medium-sized planter.

Winter varieties, on the other hand, are larger and can grow up to 6 to 10 inches long and are best for storage. The Black Spanish radish and Daikon are the most common winter varieties.

The Black Spanish radish also known as Erfurter radish has white flesh with tough black skin. It comes in both round and elongated shapes. Just like the Black Spanish radish, Daikon also has white, elongated roots.

Both spring and winter radish varieties will also do well in a container gardening as long as you provide the right size of pot or container for your plants' needs.

Step 2: Choose the Right Container

Choosing a container for growing radishes depends on what variety you're growing. Large containers with good drainage and can retain an adequate amount of moisture at the same time is ideal.

Select a container that is at least six inches deep for radish varieties including April Cross, Cherry Belle, and Purple Plum. Larger varieties such as Daikon require a container that is 12 to 14 inches deep.

You can grow 4 to 5 large radish varieties in a smaller container. But if you're planning to grow 6 to 7 radish plants, a planter or container that is 12 inches wide is recommended.

Step 3: Prepare the Potting Soil

Radishes will do best in well-draining and healthy soil rich in organic matter. Adding peat moss, composted manure, or some wood ashes in your potting mix is also a good idea to allow the proper growth of the roots.

If potting mix isn't readily available at home and you only find heavy or clayey soils around, don't fret!

Clay soil will also work for growing radishes in containers as long as you add organic matter such as chopped leaves, weathered sawdust, or garden compost between plantings to promote ventilation.

Step 4: Sow the Seeds

Fill your planters or containers with potting soil, then sow the seeds directly 1/2 inch deep and provide space at about 1 to 4 inches apart, depending on the radish variety.

Don't forget to leave at least one-inch space between the edge of your container and the first row of radishes so the root growth won't get obstructed.

Place the container in a location where it gets enough sunlight. Make sure to water regularly, then wait until the seeds germinate after 5 to 10 days.

Early developing radish varieties including Cherry Belle can be harvested 20 to 30 days after planting while large varieties such as Daikons will completely mature after 60 to 70 days.

Step 5: Water Regularly

Avoid the soil from drying out because it may cause the radish to become bitter and woody. Radishes need plenty of water to help the roots develop fully and healthily.

With that said, keep the soil moist and make sure to water deeply especially in the first week of growth. A container with a good drainage system is the key to tolerate the water and prevent the soil from being soggy.
