Soil & site
Average, well-drained soil. Cool weather is the real requirement — heat makes it bolt within days.
Seedling care
Cilantro has a taproot and resents transplanting. If starting indoors, use deep cells, transplant young, and disturb roots as little as possible.
Growing notes
Succession sow every 2 weeks — a single planting only gives 3–4 weeks of good leaf.
Harvest
Cut outer stems once plants reach 6 in. If it bolts, let it — the seeds are coriander.
