After Care
Rhododendrons have long been mainstays of late spring because of its spectacular clusters of showy blooms and large green leaves that often last through winter. This shrub generally performs best if they are provided with moisture and shelter. Outdoors, the ideal location to plant is in filtered shade beneath tall trees, east and north side of the house. Rhododendrons need a certain amount of chilling to develop strong flower buds. With thousands of varieties, there are rhododendrons for just about every landscape situation. Though most plants flower in the spring, there are also summer-blooming varieties that add color and charm to the garden. In very cold weather, sun and wind can severely damage plants. Protect roots from damage by mulching root area after soil has frozen. Source, Sunset Western Garden Book.
