My Lord Baltimore Hibiscus plants are blooming beautifully, but they're very "floppy". They're about 4 years old, so I think they're sited o/k. My question is: has anyone tried to prune Lord Baltimore's in the spring to encourage more stalks? I'm not talking about cutting them back for spring clean up, but rather more of a "pinching" technique. I'm hesitate to try this, but was wondering if anyone else had & what the outcome was.

Would appreciate any feedback.
