Q. Several of my Rhododendrons bloomed for a second time this season. A. Rhododendrons and azaleas often rebloom.
Reasons are usually weather-related.
Reblooming often follows a period of stress, such as heavy rain and cool temperatures after a drought, although it happens occasionally even when growing conditions are good. Weigelas and spring-blooming magnolias are other plants that sometimes rebloom, especially in response to heavy pruning. It doesn't seem to compromise their vigor. Your Rhododendrons should bloom normally next year. Q. I love tree peonies, but the flowers are so heavy that they droop.
