Radishes

Radishes are quick maturing cool-season vegetables for spring and fall gardens.

 

They are ready to harvest within 4 weeks of planting and rapidly pass into a pithy, unusable condition. Radishes that produce only tops result from being planted too thick (late thinning), too much shade, or hot temperatures. Black spots in radishes may indicate boron deficiency. Dissolve 1 level tablespoon of household borax in 3 gallons of water and apply to 100 feet of garden row. Use proportionately smaller amounts for shorter rows.

Some large-root types designated as winter radishes are recommended for the fall garden. They remain crisp longer than small types, are more pungent, and are best grown like fall turnips.
