Questions

When should I plant watermelon in California?

In San Jose, plant out from February 15 to March 1. Across California the window opens between February 15 and January 14, depending on the local last frost.

How is this date worked out?

Start seeds indoors 3–4 weeks before the last frost; plant out 2–4 weeks after the last frost; sow outdoors 2–4 weeks after the last frost. Frost dates are NOAA 1991–2020 averages for the weather station nearest each city.
