Cilantro in Zone 2a & 2b
Coriandrum sativum
When to plant cilantro in zone 2b
Zones 2a and 2b share the same average frost dates in our data, so this page covers both.
Method: Direct sow: Direct-sow outside. Cilantro doesn't transplant well, or doesn't need the extra time indoors.
| Start indoors | Not typically started indoors |
|---|---|
| Direct sow / transplant outside | May 20–May 27 |
| Estimated harvest | Jul 9–Jul 16 (~50 days after direct-sowing) |
Spacing: 9 per square foot (square-foot-gardening spacing). Mature height: 1-2 ft.
Cilantro is a short-lived crop in most climates: it wants cool weather, grows fast, and bolts to flower the moment heat sets in, converting its leaves' flavor from bright and citrusy to soapy and thin almost overnight.
How cilantro fits zone 2's season
Zone 2b's frost-free window runs about 104 days, from May 20 to September 1. Cilantro needs about 50 days from sowing to first harvest.
Good companions
- Spinach: Both are cool-season, non-competing companions.
