 I've got three bushes in the front of my house, but the bushes have overgrown the sidewalk. Can I prune them back? Yeah, I would take them back about a foot or so just to get them in check and then see what happens with the blooming. And then maybe by August 15th, that's the last cutoff date, you can give them about a third, cut them back about a third so they'll get better in check. But right for now, take off about a foot or so. It'll make a big difference.
