Cilantro grows to be a leafy green plant with a taste valued in Southwestern and Mexican dishes. It is a great, low hassle culinary herb to plant in your garden. Even the seeds are edible--the seeds are known as coriander. In some temperate climates, cilantro acts as a perennial, coming back year after year. It is easy to plant cilantro from seed, but you do need to know its favored growing conditions to grow healthy plants. For best results, plant in early spring, when the danger of frost has passed for your area.
Choose an area of your garden for the cilantro. It should be an area that receives at least a few hours of sunlight each day. Plant the seed directly in the garden, rather than starting it in pots. According to Tropical Permaculture and Northwest Gardening, cilantro does not start off well in shallow seed pots and won't transplant well--therefore it is wisest to plant it directly in the ground.
Break up the soil with a hoe. Add 3 to 4 inches of compost to the soil, recommends the University of Illinois Extension. Use a hoe to work this into the soil and then use a rake to level the soil.
Turn your sprinkler on to dampen the soil. It doesn't need to be soaked, just dampened. This helps secure the seeds on the soil as you plant.
Plant the seeds 2 to 3 inches apart. If you plant them a little closer than this, it is OK--you can thin them out once they start growing to keep plants at least 3 inches apart.
Cover the seeds with a 1/3 to ½ inch of soil. Keep them moist as they prepare to germinate. Use a soaker hose instead of a standard garden hose to keep the seeds from washing away.
