Jose, you're right, I've rooted it without rooting hormone fine. I guess I need to try with it and with out it to know the real results. This rooting hormone contains fungicide which may prevent mold. In your dry climate I can see why you need to remove it slowly.
This is the same way I was able to root many softwood cuttings such as Grape vine, Kiwi, Pomegranate, and mulberry.
