SOWING: Radishes require well drained soils with a pH range of 6-7.0. Direct sow at any time during the season, beginning in early spring into early fall. Plant about 10 seeds/ft, 1/2″ deep, rows 1′ apart. Radishes are adversely affected by hot, dry weather. They remain in prime condition only a few days and should be grown rapidly with plenty of moisture to be mild, tender, and attractive.
HARVEST AND STORAGE: Harvest promptly to avoid pithiness, beginning at about 3-4 weeks when roots are the size of a large marble. Wash with cool water and refrigerate. Radishes will keep 3-4 weeks in good, crisp condition if kept at 32°F and 95% relative humidity.
AVG. DIRECT SEEDING RATE: 1 oz./70′, 14 oz./1,000′, 21 lb./acre at 35 seeds/ft. in rows 18″ apart, or 31 lb./acre in rows 12″ apart.
