Q.Pruning Hibiscus
I have a tropical hibiscus tree that I kept outdoors all summer. This is my third year for my tree. Now the leaves are turning yellow and I had fertilized it two times this past summer, but no flowers. How far do I need to prune this tree back for the winter? It has a twisted trunk too. I would love to see it bloom again next summer. Can you help me?

We would also say to use a low nitrogen fertilizer or a high phosphorus fertilizer to help it bloom.
