DAYS TO GERMINATION: 7-10 days at 65-70°F (18-21°C)
SOWING: Direct seed (recommended) - Direct seed spring through late summer. Sow 1/4- 1/2" deep, 1/4- 1/2" apart in rows at least 3" apart. For leaf harvest, there is no need to thin, as cilantro continues to grow well even when sown thickly. For coriander seed production, thin to stand 2-4" apart. Successive sowings can be done every 2-3 weeks for continual harvest of leaves.
LIGHT PREFERENCE: Sun. In most locations, bolting is likely in the heat of midsummer.
PLANT HEIGHT: 12-18".
PLANT SPACING: 1/4- 1/2".
HARDINESS ZONES: Annual.

The immature seeds are sweet and fresh and can be harvested after they form on the flowers, until they become brown and dry. Mature seeds are produced about 3 months after planting and are harvested when dry on the plant.
SOIL REQUIREMENTS: Does best in rich, well-drained soil.
