Pea in a Zone 9 season
Zone 9 gives about 275 frost-free days. Pea needs roughly 60 days from sowing. That leaves about 215 days of slack, so there is room for a late start or a second planting.
How to grow peas
Peas like cool weather. Sow as soon as the soil is workable, or at the start of the cool season in mild climates. Give them a trellis and harvest before the heat arrives.
