We moved in to a house with bushes trimmed neatly, but well over the sidewalk.
Do I trim this back all at once, or over a long period of time (months? Years?)?
We are in southeast Michigan, and will have several frosts before spring really hits. When do I prune these?
The branching inside appears to be fairly well filled in with thin branches. I'm guessing a hedge trimmer will be fine, cutting everything back. If not, how should I prune them?
May help identify this bush:
