Rhododendrons and azaleas are plants that help define the landscape style of the Pacific Northwest. Varied and vivid flower colors brighten shady sites through the spring months, and bold evergreen foliage gives a lush appearance all year long.
Though some varieties have reasonable sun tolerance, all are easier to establish and maintain where protected from the hottest exposures. Add plenty of acid plant planting mix to loosen up clay soils. Keep rhododendrons and azaleas well watered in the dry summer months, and fertilize soon after flowering to maximize next year’s blooms.
While rhododendrons and azaleas can be planted year round in western Oregon, shopping in spring gives you an opportunity to see different varieties in flower before choosing one to take home.
