Pruning Bush Stuff

I overheard NBC4's Tom McNutt talk about pruning the other day.
He reminded viewers to:

• prune early springtime flowering "stuff" (like lilacs, azalea, forsythia) immediately after they are done blooming, so usually late spring to early summer
• prune evergreen shrubs in late spring- early summer (can start to prune around Christmas holidays to use for decorations, and then finesse the pruning in late spring after the new growth has appeared).
• prune things that flower in the summer (like some hydrangeas, rose of sharon, butterfly bush, redbud) in early spring, like February or March- right before the upcoming growing season.
