When it comes to gardening, understanding companion planting can be a huge help, but oftentimes feels very complicated. There are many charts floating around online that almost seem impossible to understand. Luckily, companion planting with radishes is an easy task! Keep reading to find out how to get started.

Tips for seeding radishes

Radishes are simple vegetables to plant and grow. They can be sown into your garden as seeds early in the spring for an early harvest or in the fall for a later harvest as they prefer colder temperatures and are frost tolerant. Radishes germinate quickly, in 3-5 days, and about a month after they sprout, they are ready to harvest. 

Plant your radish seeds about ½ an inch in the ground and about 2 inches apart, or as directed on the package of seeds you purchased. Radishes prefer full sun. If using landscape fabric to prevent weeds, burn a row of holes into the fabric with a small torch and dig up a small amount of dirt to plant your seeds in. 

Choose your type

There are many types of radishes you can choose from. You’ll want to consider taste preferences as well as what you want your vegetables to look like. My favorite radishes to grow are watermelon radishes which are big, mild, and white or green on the outside with beautiful bright pink flesh in the middle.

Traditional radishes you might find in the grocery store are Cherry Belle, Crimson Giant, or Early Scarlet Globe. These are all smaller, red, crisp, and tender radishes. 

Another popular choice are Daikon radishes which tend to be white, purple, or pink and longer vegetables. Diakon long radishes can grow up to 14 inches long. Purple daikon are purple on the outside, white in the middle, and are often used in Asian dishes. 

Companion planting for radishes

Radishes are a good companion to most vegetables so you don’t have to be choosy about where you place them. I prefer to keep radishes close to other root vegetables simply for the ease of remembering where I put them. In my garden, the radishes are in a row by my carrots, beets, and peas. 

Avoid planting radishes near plums because they will inhibit each other’s growth. You might also avoid putting radishes under tomato plants or climbing cucumbers as radishes prefer full sun and won’t appreciate the shade provided by taller plants.

Harvesting and cooking radishes

Harvesting radishes

Radishes are ready to harvest very quickly. About 3 weeks after planting, many varieties are ready to go. When you pick radishes, pull from the base of the stem, near the plant. Brush off the excess dirt, trim the leaves, and wash and dry your radishes before storing. 

Eating radishes

Many radishes can be enjoyed raw. Slice them and eat with vegetable dip, a sprinkle of salt, or plain. Alternatively, you can cook radishes, which will sweeten their flavor. Sauté, roast, or air-fry radishes.
