Frequently asked questions
What growing zone is California in?
California’s ZIP codes span USDA zones 5b to 11a, and 9b is the most common. Zones vary with elevation and distance from water, so check your own ZIP code.
When should I plant?
Hardiness zones are about winter cold, not planting dates. For timing, use the last spring frost date for your city on our California frost dates page.
