Pruning a Rose of Sharon
Surprisingly, a rose of Sharon doesn't need pruning as long as there is plenty of space for it stretch and grow. However, if you want it to look in shape and not wild in your garden, then the best time to prune them is in late March to early May.
Remember, if you live in cold climatic conditions, you need to carry out this task during late winter or early spring. First, you need to remove any dead or diseased parts of the plant; cut them down to the ground. Then, thin out the crowded stems at the base; you can cut them back to 2 buds. This will help encourage growth of larger flowers.
