I tried a few soft-wood cuttings of Rose of Sharon as an experiment during the spring. I had just so-so success. I was told to do this for hard-wood cuttings of Rose of Sharon: Wait until after a frost to cut your limbs. There should be several nodes on each cutting. Treat them with Rootone and insert them into a mixture of perlite and sand (need good drainage). This person used a cat littler box because of the size and depth. She also placed the box inside a white trash bag - black and clear are not advisable. She told me to leave the box inside the bag outside somewhere in a protected area and do not disturb it. In the spring, I should expect the cuttings to be rooted. Mind you, I have not tried this yet, but I could see from her offerings at her nursery that she knew what she was doing.
