Working in Templeton
Climate & hardiness zone
Templeton sits in USDA Plant Hardiness Zone 9a, with winter minimums of 20–25°F. Cooler than most of coastal California, Zone 9a sees real frost and occasional freeze events that drive plant selection and irrigation strategy. Contractors need to understand which ornamentals will die back and which will be damaged outright, and irrigation systems need reliable winterization. The upside: Zone 9a supports a wider range of temperate species than warmer zones, giving experienced designers more to work with.
