Select a container at least 10 inches deep.
Fill the pot with a fast-draining potting soil.
Before seeding, moisten the soil. mix the seeds in a bowl with sand (3 parts sand to 1 part seed). Sow the seeds, then cover lightly with soil.
Gently mist the soil so as not to displace the seeds.
Place containers in full sun or, if you live in a hot climate, light shade. Seeds should germinate in 7 to 10 days.
Harvest at least weekly to keep leaves coming. Using this method, it's possible to harvest four crops of cilantro from a single pot.
