How to Harvest Cilantro. 1  Cilantro leaves can be cut at any time during their growth period, but waiting until the plant is about 6 inches tall will give you optimum leaves.  Cut the outer leaves first, allowing the smaller leaves that are closer to the stalk to continue to grow and mature.
Planting. 1  Plant cilantro in the spring after the last frost date or in the fall. 2  In the Southwest, a fall planting may last through spring when the weather heats up again. 3  Do not grow in summer heat as the plants will bolt (so it is past harvesting). 4  The leaves that grow on bolted plants tend to be bitter in flavor. You can then store the seeds in sealed containers. 2  To store cilantro leaves, you can either freeze or dry them. 3  To freeze, put the leaves in a resealable freezer bag and store them in your freezer. 4  To dry them, hang the plant in a warm place until fully dried, then store the leaves in a resealable bag or container.
