Learn about these unique varieties of radishes to grow in your garden.
Forget those wimpy little radishes found on relish plates. They pale in comparison to the unique varieties of radishes you can grow. Consider sweet, rose-fleshed, green-skinned "Shinrimei" radishes, zesty Japanese daikons or even crunchy, mustard-infused radish pods.
Some weigh up to 5 pounds apiece. Others offer a color explosion. Still others impart cooked dishes with subtle flavors that are the hallmark of some ethnic foods. Now these are radishes!
Esteemed by the Greek god Apollo, cultivated by Egyptian pyramid builders and eaten for breakfast by American settlers, the radish has been around forever. It was prescribed by physicians to prevent scurvy, used by herbalists to ward off women's chatter, and salted or pickled to accompany food and drink throughout recorded time. The radish is still so revered there is a Night of the Radish — La Noche de los Rabanos
Choose Cool Conditions When Growing Radishes
Most of the exotic radishes are best planted in late summer or fall (fall-planted) for a winter crop, or in early spring, as soon as the ground thaws. Warm-climate gardeners do best to plant in late October. Cool soil and air temperatures are needed to develop flavors and avoid building heat, which can mask the subtleties of the various undertones. If you're growing a radish for storage, Jeremiah Gettle, owner of Baker Creek Heirloom Seeds in Mansfield, Missouri, suggests it should be fall-planted. "After harvest, store them in sand or sawdust to maintain moisture, like you would a carrot, and they will improve in flavor." he says. "it takes cool growing conditions to produce a sweet radish." He plants in late August and harvests in early November in his USDA Zone 6 gardens. Some varieties, like 'Black Spanish Round,' contain much of their heat in the skins. Removing the skin helps tame particularly hot radishes.
Some radishes are grown solely for their edible seed pods, and they, too, produce the highest quality crop in cool conditions, Because they can mature in as little as 30 days after sowing, podding radish varieties, like 'Munchen Bier,' 'Madras' and 'Rat Tail,' can be planted in very early spring, too. However, if spring is short-lived in your area, fall planting is advisable. "Pick the pods when they are young and tender for best flavor," says Bill Adams, retired Texas extension service agent and vegetable specialist in Houston. Pods can be green or have a purple hue and are attractive salad ingredients. They have a mustard flavor people either love or hate. I like the bite and use them in stir-fry," says Melinda Smith, a former Massachusetts organic farmer, who now conducts a farming apprentice program. "But they were not the hit with my produce customers like I thought they would be."
Since they mature rapidly, exotic radishes prefer a stress-free growing environment, in addition to cool temperatures. Start with fertile soil that has plenty of organic material incorporated into it. Dig a 1-inch layer of compost into the bed and work the soil to a depth of at least 8 inches. Japanese daikons will grow 20 inches or more into friable soil. Don't be surprised to see up to one-third of the radish growth above ground, though. Such growth is typical of Asian radishes, including Chinese varieties.
Sow seeds and grow exotic radishes as you would small red ones. Maintain a steady supply of soil moisture, so plants are never stressed. Thin plants to stand 6 inches apart (8 inches for daikons) after two sets of true leaves appear. Flea beetles and root maggots, the two major radish pests, can be avoided by placing floating row cover over the bed.
If podding radishes are grown, don't cover them when flowering begins. They need insects and air movement to pollinate flowers that create the pods. Instead, spray in early morning with neem seed oil if insect pests appear. Don't use neem oil after 10 a.m., since beneficial pollinating bees will be present and the oil may burn plant leaves in full sun.

Pickled Radish Recipe
Radishes make great pickles, and you can prepare them overnight. Start with 2 cups of sliced or chunked firm radishes. Put them in a mixing bowl and sprinkle 1 teaspoon of salt over them. Cover and chill for 30 minutes. Drain accumulated liquid and rinse to remove the salt. Pat dry with paper towels and return to bowl. Add 2 tablespoons rice wine vinegar, a dash or two of ground black pepper and a couple drops of sesame seed oil. Refrigerate at least 8 hours and enjoy.
