Make your own hormone rooting liquid
Did you know you can save money and do your bit for the environment by making your own hormone rooting gel? All you have to do is pick a bunch of willow stems, put them in a glass or vase of water for about 24 hours.... that's it ! The active ingredient found in willow stems is rhizocaline, a substance which is the active ingredient in many proprietary ready-made hormone rooting powders and solutions. All you have to do is to dip your cuttings into this solution. I'm not sure how long you can keep it once made, but it is not difficult to make some more - and it's free!
