Frost and the hibiscus - Knowledgebase Question

I have a few Hibiscus which I planted about 2 years ago. Every year since we've lived here we have had a light to a somewhat harder frost. So, I cut the hibiscus back in the spring. This year they are only about 1 foot high and don't have anything on them but leaves. Do you think I am cutting them back too much? I would love to get more..but I would like some flowers. Thanks.

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.

Hope so!
