Tips, care, and planting times on the Rose of Sharon.

Please see related link below.

If you mean move from one place in the garden to another ..... at winter's end up to the point just before it puts out new spring leaves. (After the new leaves emerge, it's too late: these cannot be transplanted without loss). If you mean planting from a container-grown situation .... just about anytime you can get a shovel in the ground.
