California spans more than one climate: Zone 10 is the most common zone, but the state runs 7a to 10b. That's why the planner works from your ZIP code's frost dates, not your zone: mountain and coastal gardens in the same state can be three weeks apart.
In California: watch for
The pests that find snap peas here.
With about 334 frost-free days, snap pea spends longer in the ground here than in most of the country, which widens the window in which pea aphid can find it. Scout weekly from midseason and act on the first signs.
Clusters on the tender growing tips where new tendrils form.
Organic fix: Knock colonies loose with a firm blast from the hose before they build.
White powder on leaves after warm dry days and cool, dewy nights.
Organic fix: Grow resistant varieties and trellis so vines are not lying on each other.
Root rot
Seedlings stall and yellow from the bottom up, and a lifted plant shows soft brown roots instead of firm white ones.
Organic fix: Sow into a raised or well-drained bed, work compost into heavy ground, ease off the water, and move peas to fresh ground next year.
Your season math: California gives snap peas about 334 frost-free days, and it needs roughly 62 days to a first harvest. That fits about 28 re-sown rounds across the season, so you can keep it coming instead of picking once.
