Pruning overgrown Rose of Sharon hedge
We bought our house three years ago, and it came with an overgrown Rose of Sharon hedge consisting of eight plants that are about 12 feet tall. The hedge looks way too large for the area and the plants are growing into the canopy of a large smoke tree that was planted about 10 feet away. I've read lots suggestions about pruning ROS and have become thoroughly confused. Some people suggest a light pruning over a three-year cycle to bring the plants back to a manageable size. Others say that ROS is so durable that you can pretty much hack the plant down to size in one shot. Which option is correct? Is this a project that requires hand pruners and precise cuts, or can I use hedge trimmers and garden shears? Thank you.
