We had a very heavy late snowfall and it really did a job on a very large rhodadendrum(spelling?)we have.Some of the larger higher branches have split and what was once a beautiful bush needs help.What is the best time to trim it back,and how far should I go?
|Luckily, these shrubs will usually resprout from dormant buds in the old wood. Trim away any broken branches so that there are clean cuts rather than broken branches. Next prune as needed for shape. The shrub should recover fairly quickly because it can draw on the capacity of the now overly large root system. The best time to prune is early spring, second best time is immediately after they bloom.
