Growing watermelon radishes is as easy as growing other types. They take about 65 days to mature, which is longer than other varieties. They should be planted in the early to late spring. For a total of four to six weeks of growth, they can be planted anew every two weeks. Radishes are easy to grow, but they do require a lot of water.
You can grow them in a pot or container, or you can plant them directly in the ground. If you choose the latter, you’ll need to water them every other day or so to keep them moist. Water them once a week during the growing season.

How long does it take for a watermelon radish to grow from seed?
The watermelon radish takes 60 days to grow to maturity. It’s a good idea to harvest your radishes at the same time each year, as the peppery flavor varies with the harvest time, and I tried harvesting my watermelon radish at different sizes.
1/2 cup water, plus more as needed .5 cup fresh or frozen chopped radicchio, peeled and cut into 1-inch pieces (about 1 cup) 1 medium yellow onion, finely chopped 1 clove garlic, minced 1 teaspoon dried oregano 2 teaspoons dried thyme 2 tablespoons fresh lemon juice 1 tablespoon extra virgin olive oil Salt and freshly ground black pepper, to taste Directions: In a medium saucepan over medium heat, add the water and bring to a boil.
Reduce the heat to medium-low and simmer, stirring occasionally, for about 15 minutes, or until the liquid has reduced by half. Remove from heat and set aside to cool slightly. Meanwhile, in a large bowl, combine the chopped onion and garlic; season with salt and pepper. In the bowl of a food processor fitted with a blade attachment, pulse the onion mixture until it resembles coarse breadcrumbs.
How do you plant radish seeds?
Sow radish seeds one inch apart in rows one foot apart in loosened soil. If you want to water them gently, cover them 1/2 to 1-inch deep. For a continuous harvest, you should plant radishes every ten days. After a week, thin the radish seedlings to every two inches and plant them again. Radishes can be grown from seed or cuttings.
Seeds are available at most garden centers and at many farmers’ markets. Cut the seeds in half lengthwise and place them in a plastic bag. Place the bag in the refrigerator to keep them from drying out. The seeds will germinate in about a week and will be ready to plant the next spring.
How many radish seeds do you plant in one hole?
You can plant one per hole if you have new seeds. If they are a few years old, place two or three into each hole, then thin them out to make room for the next batches.
Radishes can be grown from seed in as little as two weeks, but they can take up to three months to reach full size. If you want to plant them in the spring or summer, start them indoors in a warm, well-ventilated area and let them grow for a couple of weeks before transplanting them outdoors.
How deep should a container be for watermelon radish?
It’s best to pick a container that’s at least 6 inches deep. Pick a pot that’s at least 12-16 inches wide if you want to grow more than one radishes. You should space them 3 to 4 inches apart. Fill the container with water and place it in the sun for a couple of days. After the water has evaporated, remove the plant from the pot and let it dry out completely.
This will allow the radish roots to get a chance to colonize the soil. Once the roots have colonized, you can transplant them to a new container. You can also use the same container for multiple plants, but you’ll need to make sure that the root ball is large enough to support the weight of the new plant.
How deep do you plant watermelon radish?
Start seeds are 1 inch apart, in rows 6 inches apart. The soil should be kept moist and weeded. Seedlings should be 6 to 8 inches tall and 1 to 2 inches in diameter at the time of transplanting.

Sow seeds in a well-drained potting mix and allow them to germinate for a few weeks before planting them in your garden.
