USDA Zones 10a–10bMost San Francisco neighborhoods fall in USDA Zones 10a–10b
Frost uncommonTypical last spring frost: February 1
Frost uncommonTypical first fall frost: December 15
Cool season

Plant through winter

Broccoli, lettuce, peas, carrots, radishes and leafy greens perform best from fall through early spring.

Warm season

Use spring warmth

Use the warmest, sunniest garden spaces for tomatoes, beans, cucumbers and squash; cool coastal summers can slow heat-loving crops.

Late summer

Restart the cool garden

Begin fall brassicas indoors and prepare beds for direct-sown roots and greens as temperatures moderate.

Spring planting

Planting Dates for Spring

Dates use San Francisco valley-floor climate timing. Intense summer heat, dry air and nearby foothill elevation can change planting and harvest windows. Always check soil temperature and the 10-day forecast before planting.

How to Read This Calendar

1

Start indoors

Sow in trays under strong light. The window is timed so seedlings reach transplant size without becoming root-bound.

2

Transplant or plant

Harden seedlings off for about a week. Perennial crowns, sets and seed potatoes are included in this column.

3

Direct sow

Plant seed directly into prepared soil. Cool-season crops can begin before frost; heat-loving crops need warm soil.

4

Last planting

This is the practical end of the selected window—not a guarantee. Variety maturity and unusual weather can move it.
