Cilantro (Coriandrum sativum) is a spice in many culinary dishes, but perhaps is best known for its use in Mexican cuisine. It is an excellent addition to the home herb garden and can be grown outdoors or in containers. Cilantro is unlike many other popular herbs, such as parsley and basil. It prefers cooler temperatures and does not regrow as well after harvest. Cilantro is frequently harvested only once. However, it can regrow a second time, albeit not as efficiently as the first.
Wait until cilantro grows at least 4 to 6 inches tall to harvest. It will take approximately 40 to 60 days after seeding for cilantro to reach this height.
Pinch or clip off cilantro 1 inch above the soil line. Some gardeners pull up the entire plant or cut it below the soil line, but to regrow the plant, pinch or clip above the soil line. Harvest an entire cilantro plant at once or harvest stems and leaves as needed once it reachs at least 4 to 6 inches tall.
Continue to care for your cilantro so it will regrow a second time. Keep it in a cool area of the garden or home, with morning sun but afternoon shade. Water it near the base of the plant and keep the soil slightly moist. Do not repot it. It does not fare well after the roots are disturbed.
