It features blooms that appear all summer long, which vary in color and range from two to four inches in diameter. The Rose of Sharon is a hardy plant, but special care is sometimes required in the winter months.
Pruning
Prune your Rose of Sharon in late winter or early spring to maintain a good size, help provide plenty of flowers and to get rid of diseased, weak or broken branches. The shrubs can grow to a height of between 8 and 12 feet; flowers bloom on new growth each year, so the branches should be cut back to a healthy bud. To thin the shrub, cut it near ground level or close to the main trunk.
Frost Protection
The Rose of Sharon does well in winter temperatures and conditions and is normally disease-resistant. The roots of shrubs planted in your landscape should be safe from freezing. Pots do not offer that same protection, but the Rose of Sharon will not thrive if taken indoors. To protect potted shrubs' roots from freezing take the pot into an unheated garage; the temperatures will stay usually between 30 and 40 degrees even in harsh winters. Since the Rose of Sharon is in a dormant stage during the winter, it doesn't require sunlight.
Alternatively, wrap and tape the pot with Styrofoam or a blanket made of insulating materials, or plant it in the ground with mulch before the first winter frost and dig it back up for potting in the spring. This will help prevent the roots from freezing and dying.
