|The hardy hibiscus (Hibiscus moscheutos) plants we grow as perennials die back to the ground naturally in the course of the winter. You may trim off the stems in late fall after the cold weather has killed them back or wait until early spring, as you prefer. Most gardeners will also use a fairly thick mulch over top of the soil each winter. The plants emerge somewhat late in the spring when the soil is finally very warm, so it is helpful to mark their location so that you do not accidentally plant on top of or step on them. Enjoy your hardy hibiscus!
