Gardening in Chelan and Douglas Counties in North Central Washington can be a very rewarding experience, but our hot and arid climate creates some challenges that affect our gardening practices and decisions.
Weather and soil conditions east of the Cascades are important factors to consider when choosing and maintaining trees, shrubs, lawns, vegetables and flowers. Residents new to the arid climate, high summer heat, and generally low organic matter in the soil will find more success growing plants when aware of these conditions. An array of plants, such as tomatoes and melons, benefit from the heat. In contrast, even with careful placement, a favored dogwood risks an appearance marred by leaves scorched by hot sun and dry heat.
Take these conditions into account when designing a landscape, garden, or irrigation system, and choosing and maintaining plants.
