Mentioning fertilizer, this family of plant requires very little in the way of extra nutrients. A yearly top-dressing of compost is really all that is needed to keep your rose of Sharon (Hibiscus syriacus) happy and healthy. If you feel that your plant is looking a bit lackluster, you can give it a light compost tea or organic fertilizer in the spring. As for the roots, they are generally deep and not particularly fussy, although they do like a bit of organic matter in the soil. If you are planting in heavy clay soil, consider adding some sand to the planting hole to improve drainage.
Pruning the red rose of Sharon is an important part of keeping this plant healthy and blooming. This plant blooms on new wood, so it is important to prune it in the late winter or early spring. This will encourage new growth and more flowers. When pruning, be sure to cut back the stems to just above where there are leaves or buds.
Propagation is generally done through rooting hardwood cuttings taken from the plant in late winter or early spring. The cuttings should be about 6 inches long and taken from new growth. The bottom portion of the cutting should be dipped in rooting hormone and then planted in a well-drained potting mix. Keep the cuttings moist but not wet and in a bright, indirect light until new growth appears, which can take several weeks. Once new growth appears, you can transplant the young plants to their permanent location.
Usually, the plant growth rate is determined by the application of fertilizer. A common rule of thumb is to apply 1/2 lb of 10-10-10 fertilizer per 100 sq. ft. of garden area. Water the area thoroughly after application. For best results, wait until after the plant blooms to fertilize.
Common problems for this kind of plant plants include leaf spots, powdery mildew, rust, root rot, and Verticillium wilt. Leaf spots are characterized by small, dark spots on the leaves, while powdery mildew appears as a gray or white powdery coating on the leaves. Rust can cause red, orange, or yellow spots on the leaves, while root rot is characterized by brown or blackened roots. Verticillium wilt can cause the leaves to turn yellow or brown and eventually drop off.
