Spinach in Zone 2a & 2b
Spinacia oleracea
When to plant spinach 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. Spinach doesn't transplant well, or doesn't need the extra time indoors.
| Start indoors | Not typically started indoors |
|---|---|
| Direct sow / transplant outside | Apr 22–Apr 29 |
| Estimated harvest | Jun 1–Jun 8 (~40 days after direct-sowing) |
Spacing: 9 per square foot (square-foot-gardening spacing). Mature height: 0.5-1 ft.
Spinach is one of the fastest, most cold-tolerant greens you can grow, direct-seeded a full month before your last frost, but it's also quick to bolt once the weather warms, so the growing window is short and worth planning around rather than fighting.
How spinach fits zone 2's season
Zone 2b's frost-free window runs about 104 days, from May 20 to September 1. Spinach needs about 40 days from sowing to first harvest.
