Cilantro
Dates below are counted from the average last spring frost or the average first fall frost. Enter a ZIP in the calendar for NOAA 1991–2020 station averages, or pick a zone and use the zone table.
When to plant
Soil and site
Average, well-drained soil. Cool weather is the real requirement — heat makes it bolt within days.
Seedlings
Cilantro has a taproot and resents transplanting. If starting indoors, use deep cells, transplant young, and disturb roots as little as possible.
In the garden
Succession sow every 2 weeks — a single planting only gives 3–4 weeks of good leaf.
Picking
Cut outer stems once plants reach 6 in. If it bolts, let it — the seeds are coriander.
