If you live in Seattle and are considering adding trees or shrubs to your landscape, fall is the ideal season to plant. Our region’s mild temperatures, steady rainfall, and relatively frost-free conditions provide the perfect environment for root development. By planting in fall, you’ll give your new trees and shrubs a strong head start before the dry summer months arrive. Use the following fall planting guide to get started.
Why Plant Trees and Shrubs in Seattle During Fall?
Spring planting often leads straight into summer drought. However, fall planting in Seattle allows roots to grow steadily through the cool, moist months. With less stress from heat and evaporation, your trees and shrubs can focus on establishing strong root systems. By next summer, they’ll be better equipped to survive our region’s characteristic dry spells without constant watering.
