Answer: Hibiscus should be pruned immediately after flowering. Now is a good time to trim yours back. Hibiscus blooms on new wood so pruning now should not delay blossoming in any way. As with all established landscape shrubs, it's best not to remove more than one-third of the live growth at any one time. Start by removing misplaced branches and then remove anything that's dead, dying, diseased, crossing or broken. Then prune to shape.
Enjoy your landscape!
