Plant Zucchini in Zone 11a

Seed-starting, transplant & harvest dates for USDA Zone 11a

Direct sow
Feb 1
Harvest (~55d)
Mar 28

Zone 11a is effectively frost-free, so the Zone 11a calendar for zucchini is set by heat, not cold. There is no last frost to count backward from and no first frost to beat, which means the question is not whether zucchini will finish but whether it will sit through the hottest stretch of the year. Zucchini is a tender crop needing about 55 days from sowing to harvest.

Planting zucchini for a fall harvest in Zone 11a

Zone 11a has no meaningful frost, so the fall and winter months are the easiest time of year to grow zucchini here. Sow from about October 1 onward.

One midsummer sowing of zucchini replaces the spring plants right as squash vine borer takes them out.

Fall dates are counted backward from the Zone 11a average first frost, not forward from a sowing date. See the fall planting calendar by zone for the full method.
