How Do You Split A Hardy Hibiscus
I have several hardy hibiscus plants. The plants are hardy in the midwest zones down to 30 degrees below zero and can double in size and grow up tp 6 feet high in 3 years. I would like to split the plants, but do not know the best time or how to do it. I need some help.

There are many species of hibiscus. The overall majority are best propagated through cuttings. However, hardy hibiscus can be divided and is usually done so in spring. It can be divided by cutting the plant in half. Stick a shovel in the middle of the plant between the stalks and cut straight down into the root ball. Then dig out from around the plant (about a foot around). Pop them up out of the ground and then replant.
