Q.Hibiscus in Zone 7
Some years ago I bought a couple of hibiscus plants online and planted in the ground. They do quite well but in the winter after the leaves dropped I’m left with multiple stocks that never quite die off. So the stocks have been cut back to ground level and each year new stocks find their way out. Now it is so very crowded. How do I divide or get those old stocks out of the way so new growth can come out and I’m not left with ugly brown at the base of the lovely plants?
This can be quite difficult, but with some heavy regenerative maintenance, you can get this thriving again. You will have to wait until the next dormancy to dig this up, but when the time comes, you will dig it up and cut it into as many pieces as you can, and feel safe cutting it into. Plant one or two of these back into the original spot and move, or pot up the others, and give them away. This will help restore it once it is old and gnarled up at the base.
