Planting Vietnamese Coriander
Vietnamese Coriander is a warm season herb in the Polygonaceae 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.
Transplant young plants outdoors 2–3 weeks after your last frost, once the danger of frost has passed.

Days to Maturity
Vietnamese Coriander reaches maturity in 60–80 days from sowing.
Vietnamese Coriander is ready to harvest after about 70 days. Harvest before the first fall frost, which will end the plant's productive season.
Conditions and Care
As a warm-season herb, Vietnamese Coriander needs warm soil and settled weather to thrive, and is set back or killed by frost. It is frost tender, so wait until all danger of frost has passed before planting out and harvest before the first fall frost.
Vietnamese Coriander grows well in partial sun and tolerates some afternoon shade, which can help slow bolting in warm weather. Sow seed about 0.25 inches deep — small seed is sown shallow and barely covered, then keep the soil evenly moist until seedlings establish.
Vietnamese Coriander belongs to the Polygonaceae family; rotating where you grow members of this family each year helps limit the build-up of soil-borne pests and disease. Vietnamese Coriander is generally grown as a single planting each season rather than succession sown.
