USDA Zone 10b planting calendar
In USDA Zone 10b, frost is rare: the average last spring frost is around 01/13 and the first fall frost around 01/09 of the following year, so the frost-free stretch wraps the new year — NOAA's median growing season here is 365 days. Plant cool-season crops from late winter; warm-season crops after the last frost.
