Rhododendron leaves curled and dry looking
I planted a Rhododendron shrub last spring, it looked nice at the nursery (and was in flower at the time) but it seemed to poop out over the summer. It looked pretty tired, and dropped a number of leaves. I didn't do anything over the winter but mulch it.
Now it's spring again, and the leaves are awfully dry looking, they are curled up. My neighbor's (established) Rhododendrons have nice, normal looking leaves.
Problems I am suspecting are: too much shade, not enough water. What do you think?
