Can anyone tell me how to root tropical hibs? I got one as a gift a year ago and would like to start some new ones. If there is a way, please tell me. This is a beautiful plant and I don't want to lose it. Thanks for any advice. Alda

I have successfully rooted cuttings in water with a couple drops of hydrogen peroxide added. Change the water often and add a couple drops of peroxide each time.

Hydrogen peroxide is a water molecule with an extra oxygen molecule. When it is added to water, the extra oxygen molecule is released so, for a breath period of time, the water is oxygenated. That helps cuttings grow roots.

But, Hydrogen Perixide will also destroy tissue (that's why it sizzles when you put it on a wound) so 2 - 3 drops is all you should add.

I successfully rooted several Hibiscus rosa-sinensis cuttings last winter. Semi-hardened new growth. I put them in a small pot of my regular potting soil (Al's 5:1:1) and put a humidity dome over them. No bottom heat. They rooted fairly quickly.
