Most of Ohio's radishes are produced on muck soils. Radishes mature fast, reaching harvestable size in 20-30 days. They have been known to mature in as few as 15 days. Preferred planting dates are early spring, August or September. Suitable crops can be obtained from mid-summer plantings.
Harvesting is by machine or hand.
Hand-harvested radishes are bunched with the tops left on. Machine harvested radishes are packaged in cellophane with the tops removed. Radishes must be harvested on time or the roots become pithy. The yellow-fleshed types are preferred over whitefleshed types. Plants have longer necks and the leaves more bloom as compared with regular turnips.
