Questions

When should I plant asparagus in California?

In San Jose, plant out from December 5 to December 19. Across California the window opens between December 4 and December 3, depending on the local last frost.

How is this date worked out?

Set out crowns 2–4 weeks before the last frost. Frost dates are NOAA 1991–2020 averages for the weather station nearest each city.
