Has anyone ever propagated streps by leaf-cuttings? One of my favorites fell over today and some of the leaves broke off. I put them in damp paper towels in a shaded area, because I want to try to start new plants -- but I'm not sure how to do it.
Do they need bottom heat? What's the best medium for rooting? Are the leaves laid on top of the soil, or inserts into the soil? Should I use rooting hormone?
