In the Bible, the Rose of Sharon symbolizes beauty and is used to describe the beauty of King Soloman’s lover.

Propagating Hibiscus Syriacus

Rose of Sharon can be planted in fall or spring, as long as there is no risk of frost.

It is more popular to plant potted plants than to start seeds indoors and then to transplant them. When transplanting, dig a hole twice the width of the pot. Set the plant in, cover and water well.

Caring for Rose of Sharon

The rose of Sharon requires full sun to part shade. Ensure to plant in an area that has good air circulation and provide protection from damaging winds or scorching sun that may burn the foliage.

The Hibiscus syriacus requires little attention and thrives even when neglected. A thin layer of organic compost or mulch can be beneficial, and mulch should be applied in the spring. Do not fertilise in late summer because it can stimulate new growth, which the plant will focus on rather than developing strong roots.

Pruning Rose de Sharon

Control size and maintain a vase shape silhouette by pruning back hard in early spring. Remove any diseased branches (leaf spot, rust). It may reseed abundantly, so be prepared to remove any unwanted plants appearing in other areas, which can be relocated or shared.
