Growing Roses in the Pacific Northwest
The Pacific Northwest’s mild climate is well suited to growing exceptional roses. With a few thoughtful practices, roses will thrive and reward you with healthy growth and abundant blooms.
Soil
Good drainage is essential. Roses dislike sitting in wet soil, so amend planting areas with compost or other organic matter to improve structure and drainage.
Sunlight
Most roses require at least six hours of direct sun each day. Choose a bright location with good air circulation to support strong growth and reduce disease pressure.
Watering
Roses benefit from deep, consistent watering—especially during dry periods. Water at the base of the plant rather than overhead to help prevent powdery mildew and other fungal issues. Deep, infrequent watering encourages stronger root systems.
Winter Protection
In colder areas of the PNW, some roses benefit from added winter protection. Mulch generously around the base of plants, and consider burlap wrapping during extended cold spells. This is especially important for tree roses, where the graft union sits high on the trunk and is more exposed.
Pruning
Proper pruning keeps roses vigorous and healthy. Deadheading throughout the growing season encourages continuous bloom. We perform a hard prune in late winter—around Presidents’ Day—cutting plants back by approximately three-quarters to promote fresh, strong growth.
Disease Prevention
Select disease-resistant varieties whenever possible and space plants to allow good airflow. Organic fungicides can be helpful in managing common issues such as black spot, rust, and powdery mildew.
With the right varieties and a strong foundation of care, roses flourish in the Pacific Northwest—bringing beauty, fragrance, and joy to the garden season after season.
