A potent source of Vitamin C, Johnsons scarlet radishes seeds make for a perfect addition to your backyard garden. These popular, fast-maturing, bright red globe-shaped radishes feature a crisp white flesh. They are reliable and ideal as a catch crop between slower-growing vegetables. Outdoor sowing from February to September, in a prepared seed bed. Sow thinly in rows 23cm apart. Cover lightly with 1.5cm of fine soil. Firm gently and keep moist. Seedlings appear for approximately 7 to 14 days. For continuous crops sow every 2-3 weeks. Thin as required. Keep well-watered and weed-free.
