Rose of Sharon: A Showy Summer Bloomer
3. Fertilize the Rose of Sharon in the spring
Overfeeding this shrub will cause its leaves to turn brown and drop, plus, fertilizer promotes foliage growth instead of blooms. Look for fertilizers that are high in potassium with a medium amount of nitrogen and low phosphorus and apply once per year. Never fertilize after July. It encourages new growth, which makes the shrub susceptible to frost damage.
