Questions

When should I plant spinach in California?

In San Jose, sow outdoors from November 21 to December 12. Across California the window opens between November 20 and November 19, depending on the local last frost.

How is this date worked out?

Sow outdoors 3–6 weeks before the last frost; sow again for fall 6–8 weeks before the first frost. Frost dates are NOAA 1991–2020 averages for the weather station nearest each city.
