QuestionAm in process of seasonal change of landscaping at sister's house. Want to know the proper method for trimming hibiscus shrubs - very elongated, about 6 - 8 feet tall!
AnswerRon, you must trim them prior to them budding. Fall is a perfect time of year to prune. Just be sure to remove no more than 1/3 of the shrub. You really cannot do any damage if you remove less than this. Pruning is not a science. It's just a matter of pruning at the right time of year, and molding the bush according to your own preference. By pruning now, you will have more buds next spring, and promote a more dense growing habit.
Good luck, and please write again if I can ever be of assistance.
