slightly off topic, though it seems as though the question of using root toner on cactus cuttings has been thoroughly addressed i would like to add my own personal theory on using rooting gel, its a chemical thing made from the blood of the mother (no good) in order to do the same thing (get plants/cuttings to root) i have come up with a clever plan, some plants create their own natural rooting hormones/enzymes, these plants will propagate easily from cuttings...so the plan is soak cuttings of the desired plant in water that the hormone excreting plant has been soaked in, in this case i site willow as our prime suspect for a rooting hormone source
