USDA Zone 10 planting calendar
When to plant peas in USDA zone 10
Sowing, transplant, and harvest dates calibrated to zone 10's 365-day season (South Florida, Coastal Southern California, Hawaii (parts)).
Key dates for peas in zone 10
| Stage | When | Anchor |
|---|---|---|
| Direct sow outdoors | October — February (the cool dry season is your spring) | No frost — plant in the cool months |
| First harvest (estimate) | ~65 days after sowing | ~65 days from sow |
Dates are zone-wide averages. Local microclimates (south-facing slopes, urban heat, lakeside warmth, elevation) can shift the planting window by 1-2 weeks within the same zone.
Why this timing works for zone 10
Zone 10 has average annual minimum temperatures of 30 to 40°F and a 365-day frost-free window from frost rare or never to frost rare or never. Peas are hardy enough to handle light frost — and in fact prefer cool weather. They bolt or turn bitter once daytime temperatures consistently climb above 24 °C, which is why earlier is better in zone 10.
Peas are the classic early-spring crop — direct-sow 4-6 weeks before the last spring frost, as soon as soil can be worked. They quit producing once daytime temperatures consistently hit 24 °C, so the sooner they go in, the longer the harvest window.
Quick-grow guide
- Sun: Full sun in cool weather.
- Soil temperature for germination: 7-24 °C (45-75 °F).
- Spacing: 2-3 inches (5-8 cm) between plants.
- Days to harvest from direct sow: ~65 days.
- Plant in cool weather and provide afternoon shade once temperatures climb above 24 °C.
Common mistakes — zone 10 × peas
- Spring planting: zone 10 springs are too short — sow peas in autumn for a winter and early-spring harvest instead.
- Waiting for "warm" soil — these crops germinate at 7-10 °C and bolt the moment summer heat sets in.

Crop timing offsets calibrated against US Cooperative Extension Service publications (UNL, UMN, NC State, Texas A&M, UF/IFAS) and cross-checked against the RHS sowing calendar for en-GB readers.
