Can you cut overgrown shrubs below the window line without killing them?
Older, neglected shrubs can be cut drastically below the window line before spring growth starts, provided the species tolerates heavy pruning. This heavy cut allows the bushes to grow back in full and block fewer windows without requiring you to rip them out entirely.
