Sow thinly into finely raked, warm, weed-free, moist soil at a depth of 6-12mm (¼-½") in rows about 30cm (12") apart. Germination 8-20 days. Thin seedlings by degrees to 20cm (8") between plants. Grows best in well cultivated soil. Water freely during periods of dry weather. Not frost hardy so protect with cloches to prolong the season. N.B. Recommended only as an autumn vegetable. Earlier sowings may induce bolting (running to seed). Sowing to Cropping: 14-16 weeks.
