Radishes require friable, well drained soils with a pH range of 5.8-6.8. Sow at any time during the season, beginning in early spring. Use 2-3" wide bands, seeds about 3/4-1" apart (about 35 seeds/ft. except 10 seeds/ft. for 624 Red Meat and 616 Nero Tondo), 1/2" deep, rows 1' apart, or any row or bedding scheme that will eliminate unplanted ground to discourage weeds.
