Answer: Hibiscus blooms best when the weather is hot and they get lots of sunshine. As long as your plant is putting out healthy new growth, you're not cutting it back too far, it just isn't getting the heat and sunshine it craves. If you're feeding on a regular basis, try using a fertilizer with a lower nitrogen content. Too much nitrogen can result in lush green growth at the expense of flowers. Feed in the spring with a 5-10-10 or 10-20-20 formulation and see if that makes a difference.
