Plant Hardiness Zones in Washington
Areas in Washington Where Plants Are Most Likely to Thrive
Not all plants thrive under the same temperature and climate conditions. Therefore, it is important to know your state’s climate zone so you know what plants you can successfully grow there. Most gardeners use the USDA Hardiness Zone Map to determine what plants thrive in a specific location. The map is based on the average annual minimum winter temperature, divided into 10-degree F zones. Below is the growing zone for Washington. Washington is divided into two distinct climate zones by the Cascade Mountain Range. Western Washington is more densely populated than Eastern Washington. It also rains more often.
The time in which you should plant your seeds or transplant them outside depends on what planting zone in Washington you live in. We recommend growing apples, grapes, cherries, and raspberries here.
