How & When to Harvest Cilantro

Cilantro is a cool-season annual herb grown by gardeners around the world. The plant is a relative of the carrot and does develop an edible taproot, although the leaves of the plant are commonly used as a food seasoning. If the blooms of the cilantro plant are allowed to mature and form seeds, those seeds are known as coriander. Growing and harvesting the cilantro leaves requires basic garden knowledge and almost no tools or equipment.
  1. How to Harvest

    • Although the entire cilantro plant is edible, the leaves are commonly used as a seasoning in food. Use your fingernails to pinch off the leaf at the main stem.

    When to Harvest

    • Harvest the cilantro leaves as soon as they form and throughout the spring and early part of the summer before the plant blooms and goes to seed. Pinch the leaves in the morning and keep in water, similar to a fresh cut flower, until ready to use. This period between planting and blooming, the period cilantro leaves can be harvested, lasts about two months or until soil temperatures warm to about 75 degrees Fahrenheit.

    Keep it Fresh

    • Plant separate batches of cilantro seeds in the garden about four weeks apart. This guarantees a continuous supply of the herb fresh from the garden. Even growing a few plants at a time is commonly sufficient as the leaves have a strong flavor.

    Harvesting Coriander

    • Some gardeners allow the cilantro plant to bloom and go to seed. Once the seeds have turned brown, cut the entire plant off at ground level. Place the plant upside down in a paper bag and hang in a dry area. As the plant and seeds continue to dry, the seeds will fall and accumulate in the bottom of the paper bag. Winnow out any dried leaves and debris and the remaining seeds can be ground for coriander.
