Willow rooting hormone

11 years ago

Do any of you use willow cuttings to make your rooting hormone? If so, do you find it necessary to heat the solution and why? Do you use heat to speed up the process or to partially sterilize the material. I have been cutting thin (1/2 inch) willow branches into 2 inch pieces and placing them in a gallon of water in the sun and the water turns brown after a couple of weeks. I am now watering some my cuttings with it, has anyone else tried this?
