Culture: Winter radishes are slower-growing than the quick summer kind. Many grow deeper roots than summer radishes, often cylindrical in shape. Use wire hoops and row cover to keep out flea beetles. Thin to 6" apart. They hold much longer than summer radishes but if they start to bolt, pinch off the tops. Ideal in September and October from an early July planting, and can be stored for winter in a root cellar like carrots and beets in slightly moistened sand or layered in damp raked leaves.

Disease: FY: Fusarium Yellows
Note: We cannot ship packets greater than ½ oz. (14 grams) of radishes into the Willamette Valley. The State of Oregon prohibits shipping any commercial quantity of untreated Brassica, Raphanus or Sinapis due to quarantine
