Should I be pruning hydrangea and rhododendron s now?

Rhododendron should be pruned immediately after the flowering has stop. Hydrangea pruning really depends on which one it is.Most bloom on old wood. Wait until spring as the new growth emerges to be able to distinguish which wood is dead and needs to be removed

The time to prune Rhododendron and Azaleas is immediately after flowering so you don't remove any flower buds for next year. When you prune, be sure to prune back to a growing point to maintain a healthy shrub. These plants begin making their buds for next year in the fall.

You may prune the hydrangea down as much as you want really. But best to prune it before August so as not to risk the blooming for next season.

The best time to prune is just as the flowers begin to fade. During the summer .
