How to propagate hibiscus
Wait until the summer to propagate hibiscus.
At the ends of the branches, look for stems that are smooth and dark green with plenty of leaves. A healthy hibiscus will have plenty of new growth to choose from.

Choose your answer from: --This is because in the summer, just young hibiscus will be left exposed to air currents and some sun radiation. This happens because of pollination, and when the bonsai flowers sprout, the leaves turn green, somewhat dependent on sunlight exposure.. --It's okay to take cuttings from stems that are slightly brown or darker green, but they must be rooted in topsoil to be successful. Select branches with smooth, green growth.. --As with your aloe, hibiscus plants tend to stem a little over 2 inches (5.6 cm) long. When you see a bunch of different growths, try cutting them back.. --Dig around the base of the hibiscus to get a few inches of stem stem. The stem should be slightly shorter than the rest..
The answer is:
It's okay to take cuttings from stems that are slightly brown or darker green, but they must be rooted in topsoil to be successful. Select branches with smooth, green growth.
