Working in Walla Walla

Climate & hardiness zone

Walla Walla spans a USDA hardiness zone outside California's most common landscaping climates, which means plant selection and irrigation strategy need to be matched carefully to local winter lows and summer heat. Ask any contractor you hire whether their plant choices and irrigation design are rated for your specific zone — local climate experience is the difference between a planting that establishes and one that struggles.
