How to Sow
Coriander is what the seeds are called. Cilantro is the green plant that produces the coriander seeds. Sow coriander seeds outdoors in full sun after danger of frost. In frost-free areas, sow from fall to early spring. Grow coriander seeds with herbs and vegetables in the garden or in a container. Sow seeds thinly and cover with 1/4" of fine soil. Firm lightly and keep evenly moist. Cilantro seedlings emerge in 14-21 days.
How to Grow
Thin to stand about 12" apart. Sow coriander seeds every 3 weeks during the growing season to ensure a steady supply.
Harvesting
Harvest the cilantro leaves before the flower stem has developed. Harvest the coriander seeds once they start turning from green to gray-brown. The leaves do not dry well, so use them fresh in Asian and Mexican dishes; the taste is better than the smell. The ripe seeds are an important ingredient in curry. They are also used as a pickling spice or sugar-coated and eaten as a candy.
