Growing Information

How to plant:

Propagate by seed

Germination temperature: 55 F to 85 F

Days to emergence: 3 to 4

Seed can be saved 4 years.

Maintenance and care:

Grows best in cool (50 F to 65 F), moist weather. Hot weather reducesquality and increases pungency. Late plantings may bolt before edibleroot forms.

About3 to 6 weeks before average last frost, direct seed ½ inch deep, 1 inchapart, in rows 12 inches apart. Thin to about 2-inch spacings. Crowdedplants may not produce high-quality roots. Use thinings in salads.

Forcontinuous harvest, make additional plantings every 1 to 2 weeks untiltemperatures average in the mid 60s F, or plant varieties withdifferent maturity dates in a single planting. Resume planting whenweather cools in fall.

Plant most winter varieties so that theymature around the first fall frost date. (Frost improves flavor andtexture of most winter varieties.) Larger winter varieties need morespace than spring varieties, so thin to about 6-inch spacings,depending on variety.

Keep soil moist for uninterrupted growth and best quality.

Adding nitrogen fertilizer or nitrogen rich manure close to planting may produce lush tops and small roots.

Canbe sown in the same row with carrots, parsley, parsnips and other slowgerminating crops. The radishes help to break soil crust for the weakerand later-germinating crops.

Because they mature quickly,radishes make a good intercrop along with slower growing crops, such asother cabbage family crops, or tomato- or squash family crops. Orfollow radish harvest with summer succession crops such as beans, orfall-harvested crops.

To help reduce disease, do not plant radishes or other cole crops in the same location more than once every three or four years.

Pests:

Cabbage root maggots - Use row covers made of nonwoven fabrics. Hoopscan be used to make a tent area over rows or as floating row covers.For fresh radish, weekly plantings can be made. Some will avoid maggotattack.

Diseases:

Clubroot - Locate new plants in part of garden different from previousyear's location. If soil is infested, add lime to raise soil pH to 7.2.

Varieties

Thefamiliar spring radishes are small and fast-growing - usually ready forharvest in 3 to 4 weeks. Select varieties based on size and shape(globe or cylindrical), color (including red, purple, white andcombinations) and bolt-resistance.

Summer radishes are similar, but take slightly longer to mature -- usually in about 6 to 8 weeks.

Winter radishes (Raphanus sativus var. niger)grow more slowly (usually 2 months or more to maturity), produce largerroots (usually cylindrical), and hold their quality much longer thancommon varieties. They are also known as Oriental, Daikon, Japanese,Chinese, or Spanish radishes. Most are biennials that do not bolt asreadily in response to long days, and only develop seedstalks afterexposure to cold temperatures. They are usually planted in summer forfall harvest.

Varieties recommended for New York include:
