Pea in Zone 10a & 10b
Pisum sativum
Yes, pea grows in zones 10a and 10b. Plant it outside in Sep–Jan. For a fall crop, plant out in Sep–Jan.
When to plant pea in zone 10b
Zones 10a and 10b share the same average frost dates, so this page covers both.
Method: Direct sow: Direct-sow outside. It doesn't transplant well, or doesn't need the extra time indoors.
| Window | Fall window |
|---|---|
| Start indoors | Not typically started indoors |
| Direct sow / transplant outside | Sep–Jan |
| Estimated harvest | ~60 days after direct-sowing |
Spacing: 8 per square foot (square-foot-gardening spacing). Mature height: 3-6 ft.
Zone 10b dates sourced from growinginthegarden.com.
Fall window: the last sowing date is the average first frost minus days to maturity, the method in Purdue Extension's fall garden guide, which lists pea for late-summer planting.
Plant alongside it in zone 10b
These go outside within two weeks of pea in zone 10b, so one planting day can cover them.
Peas are one of the few crops meant to go in the ground while it's still cold, direct-sown weeks before your last frost, while most of the garden is still just a plan on paper. They're also one of the few nitrogen-fixers in a typical vegetable bed, quietly benefiting whatever gets planted near their roots.
How pea fits zone 10's season
Zone 10b's frost-free window runs about 324 days, from January 30 to December 20. Pea needs about 60 days from sowing to first harvest.

Zone 2 sows before zone 3 here, which looks wrong and is not. USDA zones rank winter cold, not season length, and zone 2 is mostly interior Alaska, where hard winters come with warm summers. More on what a zone measures.
