Q.transplanting Rose of Sharon
Our city doesn’t allow a privacy fence at our location so planting several Rose of Sharon would provide natural privacy. A friend has dozens of them and offered us as many as we wanted. However, he is moving soon so we need to transplant now. Worst time for it, I know. Any chance I can do so without killing them off?

Transplanting a Rose Of Sharon needs to be done during dormancy, which is usually November through March.

You can however take cuttings from the plants and grow your own new plants.
