Growing Radishs


Radish is a cool-season, fast-maturing, easy-to-grow vegetable. Garden radishes can be grown wherever there is sun and moist, fertile soil, even on the smallest city lot. Early varieties usually grow best in the cool days of early spring, but some later-maturing varieties can be planted for summer use. The variety French Breakfast holds up and grows better than most early types in summer heat if water is supplied regularly. Additional sowings of spring types can begin in late summer, to mature in the cooler, moister days of fall. Winter radishes are sown in midsummer to late summer, much as fall turnips. They are slower to develop than spring radishes; and they grow considerably larger, remain crisp longer, are usually more pungent and hold in the ground or store longer than spring varieties.

When to Plant

Spring radishes should be planted from as early as the soil can be worked until mid-spring. Make successive plantings of short rows every 10 to 14 days. Plant in spaces between slow-maturing vegetables (such as broccoli and Brussels sprouts) or in areas that will be used later for warm-season crops (peppers, tomatoes and squash). Spring radishes also can be planted in late winter in a protected cold frame, window box or container in the house or on the patio. Later-maturing varieties of radishes (Icicle or French Breakfast) usually withstand heat better than the early maturing varieties and are recommended for late-spring planting for summer harvest. Winter radishes require a much longer time to mature than spring radishes and are planted at the same time as late turnips (usually midsummer to late summer).
