Tradition Azaleas turned brown
I planted 8 Tradition Azaleas in my front yard last year - three in one location and 5 in another area of the front yard. Along with these I planted a bunch of other azaleas/rhodies/mountain laurels, sandcherrys, and lilies. They all did well throughout the summer/fall. I kept them watered all year and they all appeared healthy/green/growing. Then in the late fall/early winter, all 8 of the Tradition azaleas turned brown. The other types of azaleas, the rhodies and the mountain laurels stayed green and are growing well this spring. However the Tradition Azaleas are still brown and while I can see some green leaves sprouting out (maybe 5-6 per plant) and some buds forming (maybe 1-2 per plant), they mostly appear to be not growing at all. I keep thinking maybe I'm being impatient and they will green up, but everything else is growing/green now and so I suspect the Tradition azaleas may be dead.
Any ideas? Should they ever turn completely brown or does that mean they died over the winter? If they are dead, what would have caused only the 8 Tradition azaleas to die off while everything else did fine over the winter and appear to be doing fine this spring?
Any thoughts would be appreciated.
