Encore Azalea Problems


Encore azalea is a hybrid developed by Robert “Buddy” Lee from Louisiana. As its name suggests, this azalea produces blooms in spring and treats the gardener to an encore bloom performance in fall. By providing proper care, you can minimize problems commonly associated with this plant.

Reduced Flowering

  • For abundant flowering, azaleas need four to six hours of sun per day. If planted in a shady site, Encore azaleas will not provide repeat blooms during the year. However, too much hot summer sun will injure azaleas and cause heat stress. Select a site that receives morning sun and afternoon shade.


  • Many pests can damage azaleas. Lacebugs are a common insect that dine on leaf chlorophyll, leaving behind yellow speckles. Encore azalea is less vulnerable to lacebugs than other kinds of azaleas. Petal fungal blight, caused by Botrytis cinerea or Ovulinia azalea, causes a mold on flower petals.


  • Azaleas that exhibit chlorosis or yellowing leaves may be responding to their soil environment. Azaleas require well-drained soil at a pH of 5.5. The larger Encore azaleas are more flexible regarding different soil pH levels than smaller varieties of Encore azaleas, according to Louisiana State University.
