My perennial Hibiscus grows to tall and falls over

Parkville, MD

My perennial Hibiscus all grow so tall and then they fall over on the grown. can they be pruned in the spring and , if you do prune them will they still bloom? I stake them and tie them and they look awful like that... How can I make them grow shorter ??? and stand up on their own.

Elaine,
Try using super phosphate fertilizer on them in the spring. I also give them a dose of Milorganite in the spring. I raise about thirty of my own hybrids and they have never fallen over even when burdened with heavy flowering and seed pods.

Super Phosphate is suppose to increase blooms. Epsom Salt is suppose to form stronger stems. I think I will try both. I have about 20 also and this year a bunch of seed pods on the Moi Grande. I am also rooting cuttings. Should keep me busy this winter, if we ever have winter.
