Rose of Sharon, or Hibiscus syriacus, is a popular garden shrub, valued for its large pink, purple or white flowers that bloom during the summer months and into early fall. In general, this shrub is a hardy, resilient plant that requires very little maintenance, although one common problem is yellowing foliage.
If you are worried about a rose of Sharon turning yellow, this is usually a sign that the plant is struggling. There are usually a few issues that cause foliage to turn yellow, typically water, nutrition, pests and disease.
