Planting cilantro
Sow directly in early spring or late summer. Cilantro resents transplanting, and warm weather pushes it to flower within weeks.
Planting details
- Sow a short row every 2 to 3 weeks for continuous leaves
- Seed depth: about 1/4 to 1/2 inch
- Bolted plants set coriander seed you can harvest
Growing requirements
Cilantro wants cool weather, sun to light shade, and even moisture. In warm climates each sowing lasts only a few weeks, so repeat sowings matter more than any single bed.
Harvesting and care
Cut leaves before the flower stalk rises for the best flavor. Let a few plants finish their cycle and they will often self-sow the next crop for you.
Common mistakes
- Sowing once in spring, then wondering why there is none by midsummer
- Transplanting seedlings, which triggers early bolting
- Skipping succession sowings in climates with mild springs
Companion plants
Cilantro tucks between lettuce, spinach, and peas in cool-season beds. Let some plants flower if you want hover flies and parasitic wasps nearby.
