We live in western North Carolina and have lots of rhodos in our landscape. Unfortunately we've had a serious infestation of borers lately and are loosing a lot of nice plants. I don't know why they're so bad suddenly, but I know of other folks with the same problem. Anyway, I'm wondering if some cultivars may be more resistant than others.
Also, what can we do to save what's left other than heavy pruning? It's hard to tell when a shrub is infested before it starts falling apart, and sometimes it hardly seems worth saving...
