First, only plant cilantro in the spring or fall, before or after hot weather. A summer crop bolts, a term that means it quickly goes to seed.

Give the plants 1 inch of water per week, and then thin the seedlings once they are 2 inches tall from 3 to 6 inches apart.
At this point, water the plants only to keep the soil moist. Add a layer of mulch to the plants to keep the ground moist and cool and protect the shallow roots. Only fertilize cilantro once or twice a growing season using a nitrogen fertilizer.
Harvest the cilantro regularly. Once the weather warms up, the cilantro plant grows a stalk upon which the seeds are located. Allow the seeds to drop for a self-seeding annual plant, and then cut off the stalk.
