The Rose of Sharon shrub produces large pink or lavender flowers and reaches up to 8 feet tall. A deciduous plant, Rose of Sharon blooms in late summer and fall when most other flowering ornamentals have completed their blooming cycle. Rose of Sharon, a type of hibiscus, is a low-maintenance, drought-tolerant shrub suitable for borders and hedges in the landscape. Proper care ensures the shrub continues to thrive and provide its impressive blooms to your garden.
Prune Rose of Sharon shrubs in spring just before new growth begins. Cut out damaged and dead branches at their base with pruning shears. Remove 1/3 of the older branches at the base, then shape the remaining branches to the desired length.
Spread a 1-inch layer of compost over the soil under the shrub. Apply the compost over the ground on the area under the outermost branches of the shrub. The compost breaks down over the summer months and leaches nutrients into the soil.
Apply a 2- to 3-inch layer of organic mulch, such as bark chips, under the Rose of Sharon shrub. Leave a 2-inch space between the trunk of the shrub and the mulch, otherwise moisture in the mulch may damage the trunk. Mulch helps preserve moisture in the soil between watering.
Water Rose of Sharon from spring until fall when there is less than 1 inch of rainfall in a week. Water at the base of the shrub until the top 6 to 8 inches of soil feels moist.
Weed under the Rose of Sharon regularly, especially in spring and early summer. Mulching also helps prevent some weed growth.
