How do I divide a "hardy" hibiscus to start a new part(s) inside and leave the rest where it is?

Question

i don't want to dig up the whole thing, but start new ones to grow inside over the winter.

Answer 1

Take six inch cuttings from a non-bloomng stem, strip the leaves off the lower half, then stick in a mix of potting soil.

Keep it moist. If the cuttings wilt, cut off half of each leaf.

You can also dig and divide the hibiscus root ball in fall or early spring if it is large enough. This will not kill the plant but it will make it grow smaller.

Answer 2

Well, there are only three ways I know of to propagate the perennial hibiscus and that is either through cuttings, division of the roots or by starting new plants from seed. Personally, I've found division to be easiest. However, since you don't want to dig up your plant then you will need to propagate through cuttings or seed. To take a cutting you'll need to locate a stem from new growth. It should be about as thick as a pencil and about 6 inches long. Remove the lower leaves and dip the end into a rooting hormone(optional) and place the stem into a mixture of 3 parts sand and 1 part peat. In about 4-5 weeks you should start to see roots and then you can move them to a more permanent location.
