What fertilizer should I use for Rose of Sharon bushes?
I have three Rose of Sharon bushes about ten years old, one of which is doing better than the others. They get about equal amounts of sun and are about the same size, though one blooms much more prolifically than the other. Is there a fertilizer that would be effective on bushes this size?

Yes, you can sprinkle Osmocote Flower and Vegetable food around the base of your shrubs, following the amount recommended on the package, or about 6oz for a full-grown flowering shrub. Sometimes root damage from a mole or vole can create a big difference in plants growing side by side. The amount of water and sunlight will also affect flowering.
Keep growing,
