Some overgrown shrubs can be cut to the ground and they’ll grow right back (this is sometimes called rejuvenation pruning). Typically, these are fairly vigorous shrubs that produce flowers on new wood.
But be careful – even some of the shrubs on this list may never recover if they’re not in very good health before you whack them back. And don’t forget to mulch the shrub after you’re done pruning; a nice thick layer of compost will do the trick.
The following shrubs generally respond well to rejuvenation pruning when done correctly and at the right time of year.
