Planting Cilantro

Cilantro is a cool season herb in the Apiaceae family. Getting the timing right is the difference between a strong stand and a disappointing one, so the windows below are given relative to your own last spring frost and first fall frost rather than a generic calendar date. Look up your local frost dates and count back or forward from there.

You can sow Cilantro directly into the garden 0–2 weeks before your last frost.

Days to Maturity

Cilantro reaches maturity in 45–70 days from sowing. Once ready, plants continue producing for approximately 21 days.

For a continuous harvest, sow a new batch every 14 days. Use the succession planting scheduler →

Cilantro is ready to harvest after about 58 days. Picking regularly over the roughly 21-day harvest window keeps plants productive and encourages a longer pick. Harvest before summer heat or, for fall crops, before a hard freeze, to keep quality high.

Conditions and Care

As a cool-season herb, Cilantro does its best growing in the cooler weather of spring and fall and tends to bolt or turn bitter in summer heat. It is half-hardy — it withstands light frost but should be protected from a hard freeze.

Cilantro needs full sun — give it at least six hours of direct light a day for the best growth and flavor. Sow seed about 0.25 inches deep — small seed is sown shallow and barely covered, then keep the soil evenly moist until seedlings establish.

Cilantro belongs to the Apiaceae family; rotating where you grow members of this family each year helps limit the build-up of soil-borne pests and disease. Because it matures relatively quickly, Cilantro rewards succession sowing: small, repeated plantings keep a steady supply coming rather than one short glut.

Companion Plants

Pairing Cilantro with the right neighbors can improve growth and deter pests; a few combinations are best avoided.

Grows well with: Basil, Spinach

Keep away from: Fennel
