Encore azaleas are a compromise. What they call a feature is considered a problem with other azaleas. They first bloom on buds that went dormant during the winter. Then they bloom on new growth. Ideally these blooms will not exhaust the buds and some buds will be left for next spring. However, I am guessing that the early spring we had and the mild fall we are experiencing will take its toll on the spring bloom.

On the bright side, Encore azaleas were developed near the Gulf Coast so they should be able to take these conditions, so hope for the best. There is nothing you can do about it except wait and see.
