Coriander, also known as cilantro or Chinese parsley, originally hails from the Mediterranean, according to Purdue University. Gardeners prize the plant for its seeds and leaves, which chefs use to add flavor to an entree. The cool-season plant is typically started in the early spring. Though you can purchase coriander seedlings and mature plants from most garden stores, planting coriander seeds is usually more economical.
Prepare the planting area. If planting coriander directly in the ground, choose a sunny location with well-drained garden loam. Stir in 4 inches of aged compost, according to Utah State University. If growing cilantro in a pot, fill a gallon-sized pot with potting soil.
Wait for the last frost date in your area to pass. If you're not sure when this is, consult the Farmers' Almanac's annual calendar of average frost dates throughout the United States.
Plant the coriander. Bury each seed 1/2 inch deep, according to Utah State University. If you're planting a row of coriander, space seeds 8 to 10 inches apart. If growing coriander in a pot, limit yourself to one plant per pot.
Water the planting area twice daily or as needed to keep the soil consistently moist. The seeds will germinate within three weeks.
