- Evergreen Azalea

(southern Indiana - Zone 6b) on Feb 5, 2015 5:13 PM concerning plant:
This azalea is a slow grower and has only been trimmed once, although it did get moved so that probably stunted it. It was dying, so I figured moving it may help, and it did.
It is susceptible to lace bug damage, which causes the leaves to turn gray-green to white and then fall off. You can tell whether the damage is caused by lace bugs because of the black spots (lace bug waste) on the back side of the leaves. New growth will occur at the same time, but treatment with insecticidal soap will help get rid of the bugs. In order for treatment to be effective, the underside of the leaves must also be sprayed.
It is listed as an evergreen, but in my zone 6b garden, the leaves that are left on it are brown and shriveled and not attractive in winter. It could probably be used as a hedge in a warmer zone.
