When can you plant in Sanger, CA?

Zone 9b

The last spring frost here typically falls around 01/14, about 139 days from today. The first fall frost typically arrives around 12/14, about 337 frost-free days later.

Zone 9b (25 to 30°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Sanger, not a forecast for this year.

What to do before the first frost

About 15 weeks of growing season left in Sanger before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

How much risk comes with planting early here

01/14 is the middle of 30 years of NOAA records, not a promise. Plant by 02/11 and you're betting against frost in roughly 9 years out of 10. 12/22 is the safer bet, historically only a 1-in-10 chance of frost that late.
