Planting Schedule

Growing in USDA Hardiness Zone 9b

A practical planting schedule for those living in the greater San Jose area.

For the most part, Silicon Valley communities fall within USDA Plant Hardiness Zone 9b. (Those living within zip codes 94041, 94043, and 94089 are the exceptions; they have been assigned a Hardiness Zone of 10a). As a result of our ideal Mediterranean climate, local growers are presented the possibility of making use of multiple plantings during a single season for many of the veggies we enjoy growing.
