How to Grow Radishes
Radishes are a tasty addition to salads and roasted vegetable plates and can be grown quickly and easily. Some varieties of radish mature in one growing season, while others overwinter and begin producing seeds in the following growing season.
When to Plant: In the early to mid-spring and early fall, plant radishes are planted outdoors as soon as the soil can be worked. For a continuous harvest throughout the season, you can plant every three to four weeks.
Requirements for Spacing Sow seeds 12 inches deep in rows spaced 2 to 3 inches apart.
Special considerations: When growing annual radishes for seed, increase the spacing between plants to 4-6 inches in rows spaced 24 inches apart. Increase the spacing between plants in rows spaced 24 to 48 inches apart when growing biennial radishes for seed.
Pests and diseases that affect radishes frequently include slugs, cabbage flies, and the flea beetle.
When and How to Harvest: Varieties that mature quickly can be harvested as soon as a month after being planted. When leaves are six inches tall, harvest them. To free the radishes from the soil, gently pull on the stem’s base.
Radishes are frequently served with salads or roasted vegetable dishes.
Developing radishes for seed represents a few difficulties for seed savers. Because radishes readily cross-pollinate, you must ensure that your crop is isolated from wild radish and other radish varieties.
Life Cycle Depending on the variety, every year or every two years. Recommended Isolation Distance Divide varieties by 800 feet to 12 miles.
Recommended Population Sizes Save seeds from at least five plants to guarantee that they will germinate. Keep seeds from 20 to 50 plants when growing a variety over many generations. Save seeds from at least 80 plants if you want to preserve a rare variety’s genetics.Evaluation of Seed Maturity Radish fruits do not split open when they reach maturity, so they can be dried in the field without fear of breaking. When fruits turn brown and become brittle, they should be picked. This takes place most of the time between the beginning and end of summer.
When about two-thirds of the planting’s seed is mature, fruiting branches can be harvested individually or as they mature. In spite of the fact that horrible seeds to breaking isn’t a worry, seed quality can diminish on the off chance that units are left in the field for a really long time after development. The mature seed stalks should continue to dry in a sheltered location after being cut on row cover or landscape fabric. When pods are completely dry, usually after one to five days, threshing is easiest.
