Working in Forest Grove

Climate & hardiness zone

Forest Grove sits in USDA Plant Hardiness Zone 8b, with winter minimum temperatures of 15–20°F — among the coldest zones in California's populated areas. This means genuine freeze events, irrigation systems that must be drained for winter, and planting choices carefully rated for cold hardiness. Contractors working in Zone 8b need cold-climate experience that many California landscapers simply don't have — it's worth asking directly about their experience with frost protection, plant hardiness ratings, and winter system preparation.
