Radishes can be stored in the refrigerator for about two weeks. Diseases are usually not a problem when radishes are grown in the home garden. Seed should be obtained from a reputable source. Insect problems that may be encountered are flea beetles, aphids and various caterpillars, such as cabbage loopers and diamondback moths. These will feed on the radish leaves.
Cutworms can be a problem for seedlings.
They will feed on the surface of the bulb. In small gardens, barriers around plants can prevent serious cutworm damage.
