Rhodoendron winter die back
We planted a rhododendron late last summer. It was very full and had several leaves. We are located on the east coast of Canada and have cold winters. This past winter was cold with lots of snow. The plant was completely buried most of the winter. Anyway, this spring most of the plant appears dead, about 75-80% of the leaves died and fell off the plant. Only a few branches are left with green leaves. Is there help for this plant? Do we cut off the dead branches? The only parts left that appear living are on one side of the plant (the plant is actually about 2' high and 2' around).
Any help would be appreciated.
