It produces an abundance of large, showy flowers in a variety of colors, including pink, white, purple, and blue. While pruning is not absolutely necessary for Rose of Sharon, it can help to maintain its shape, encourage larger blooms, and prevent it from becoming invasive.
When to Prune Rose of Sharon
The best time to prune Rose of Sharon is in late winter or early spring, before new growth begins. However, you can also prune it in late fall, after the leaves have dropped, or in early summer, after it has finished blooming.
How to Prune Rose of Sharon
The type of pruning you do will depend on the desired outcome. If you want to encourage larger blooms, you can give your Rose of Sharon a hard prune.

This involves simply removing any dead, diseased, or damaged branches, as well as any suckers or weak branches.
