Outdoors: sow thinly February-May, where they are to crop, 1.5cm (½") deep, directly into finely-prepared, light, fertile soil, which has already been watered. Allow 40cm (16") between rows. Early sowings may benefit from cloche protection. Seedlings usually appear in 14-32 days. Thin plants to 20cm (8") apart. Replace any dislodged soil. Water well until plants are established. Leave roots in the ground until required, as they improve after exposure to autumn frosts. Harvest: October-February.
