Continuous cilantro method

Steps :
  1. Select a bowl-shaped container at least 18 inches wide and 8 to 10 inches deep.
  2. Fill the pot with a fast-draining potting soil; mix in an organic granular fertilizer.
  3. Before seeding, moisten the soil using a fine spray from the hose. Because the seeds are fairly small, mix them in a bowl with sand (3 parts sand to 1 part seed) so they'll disperse more evenly. Sow the seeds, then cover lightly with soil.
  4. Gently mist the soil  so as not to displace the seeds.
  5. Place containers in full sun or, if you live in a hot climate, light shade. Seeds should germinate in 7 to 10 days.
  6. Harvest at least weekly to keep leaves coming. Using this method, it's possible to harvest four crops of cilantro from a single pot.
