Working in Napa

Climate & hardiness zone

Napa sits in USDA Plant Hardiness Zone 9b, with winter minimum temperatures of 25–30Β°F. This means a true dormant season β€” lawns and most perennials slow significantly from December through February. Contractors experienced in Zone 9b know to schedule irrigation shutdown before first frost, design planting schemes around the zone's long dry summers, and recommend drought-tolerant species that handle both the heat and the occasional cold snap. Ask any contractor you hire whether their plant selections are rated for Zone 9b minimums.
