Planting Coriander (Seed)
Coriander (Seed) 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 Coriander (Seed) directly into the garden 0–2 weeks before your last frost.

Conditions and Care
As a cool-season herb, Coriander (Seed) 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.
Coriander (Seed) 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.
Coriander (Seed) 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, Coriander (Seed) rewards succession sowing: small, repeated plantings keep a steady supply coming rather than one short glut.
Companion Plants
Pairing Coriander (Seed) with the right neighbors can improve growth and deter pests; a few combinations are best avoided.
