Propagation: Starting Hibiscus Cuttings, 1 by golddog

This method works for the majority of cutting propagation. A plastic bowl or container (no holes in the bottom). Fill to the top with vermiculite or perlite. Add water up to the top also. Dip the cutting in a rooting hormone, and place it in the medium. Depending on the environment, a 'hood' may be necessary to keep in the humidity. This may take several weeks, but is proven. For some reason the closer the cuttings are to one another, the better the success. Keep the leaf mass to a minimium and out of the wet medium. Shown is Hibiscus 'Blue River II'. I now have 12 of these plants in soil. Along with Hydrangea quercifolia 'Snow Flake', and several coleus.

Any thoughts on wintering over these new starts?
