Hibiscus tree not blooming why

Question

I wintered the tree inside. Pruned it in the fall. Out on my deck all spring and summer only one flower bloomed. Leaves are beautiful and it is full.

Answer 1

Our experts say it likely needs some fertilizer, especially phosphorus which helps with blooming. Use a "bloom booster" fertilizer or add some bone meal to the soil to help add some phosphorus. You also may need to do some pruning.
