When to Plant Cilantro Seeds
Direct Sow Cilantro seeds in the early Spring, as soon as the threat of frost has passed, but the soil remains cool. In warmer climates, Cilantro can also be sown in the Fall through Spring. Seeds can be sown at intervals of 2-3 weeks, so you can have a continual harvest of fresh leaves.
Where to Plant Cilantro Seeds
Ideal growing conditions are cool, but sunny, as soil temperatures that reach 75°F will cause Cilantro to bolt. Cilantro does best when it gets morning or afternoon sun exposure, but receives shade during the hottest parts of the day. Choose soil that is light, and well-draining.
How to Plant Cilantro Seeds
Cilantro seeds are actually a hard husk that contains two seeds inside. You'll need to crush the husks containing the seeds, and then soak your seeds for 24-48 hours, then remove from the water and allow to dry in order to increase their chances at germination. Direct sow your seeds in rows, and cover with 1/4 inch of soil. Rows should have a spacing of about 12 inches. Once seedlings grow to 2 inches tall, thin out plants to a spacing of 3-4 inches apart. Seeds will germinate in approximately 7-10 days.
How to Harvest Cilantro
Leaves can be cut at any time, but it's recommended to cut the newer, fresher leaves toward the top than to harvest the older, more mature leaves closer to the bottom for the freshest taste. Unlike most herbs, Cilantro is meant to be consumed fresh, and not to be dried for storage or later use.
