Cilantro Seeds,
Slo-Bolt

Cilantro should be planted 3-4 weeks before the last frost in spring. In warmer climates, it can be grown in the cooler months of late fall and winter. Cilantro is also frost-tolerant to some degree and can withstand light frosts, making it suitable for growing in cooler seasons​.

Cilantro should be direct-sown as it doesn't transplant well due to its taproot. Plant the seeds about 1/4-1/2 inch deep in well-draining soil, spaced 4-6 inches apart. It is important to keep the soil consistently moist until the seeds germinate, which usually takes about 7-10 days. For continuous harvest, succession seed every 2-3 weeks.

Cilantro prefers full sun but partial shade in hot weather can prevent bolting. Provide the plants with at least 4-6 hours of sunlight daily. Keep the soil evenly moist but not waterlogged, and mulch around the plants to help retain moisture. Fertilizing is generally not necessary if the soil is rich in organic matter, but a light application of a balanced fertilizer can support growth​.

Plants will readily self-seed in the garden. It is very easy to save seeds of cilantro as the plants so easily go to seed. Simply allow seeds to dry on the plant, shake them loose, and store them in a cool, dry, dark location. The seeds, often called coriander, are also used in cooking.
