Do You Need To Prune The Leaves Of Hibiscus Plants?

Q: I have three hibiscus plants. They have very large red flowers. Do you prune them back to the ground or will I get new growth from the old stems? 

A: It sounds like you probably have Hibiscus moscheutos, sometimes called swamp mallow or dinner plate hibiscus. You can remove brown stems at their base anytime after the first killing frost. Try to get it done before the first green growth appears in spring.
