Hardy Hibiscus Fall Care - Knowledgebase Question

Question by klzulpo

I planted hardy hibiscus for the first time this spring and was amazed to find my tiny bare roots bloom into 6 foot shrubs in one season! They blew over during a storm and are very dependent on the support cages I put in. Given this, should I cut the stems down to the ground once the leaves die back with the hope of new stems forming next year or do new leaves and flowers form on the same stems?

Hardy hibiscus will normally die back to the ground during the winter, so simply cut them back to the ground and remove the stems altogether once that happens. You might also place a layer of mulch atop their location. Mark their location ( maybe leave the tomato cages in place) because they emerge very late in the spring and are easily "misplaced" in the spring planting rush. They will grow to their full size again from scratch next year but should add one or two more stems to their bulk each year.
