Willow Tea as a Rooting Hormone: Willow bark contains natural plant growth hormones & thus is a FREE easy to make rooting hormone used to propagate plant cuttings. How to make Willow Tea: Collect young twigs/stems of any of willow species with green or yellow bark. Remove all leaves. Cut the twigs into short pieces about 1", & place them in a heatproof container. Cover the cut stems with boiling water, just as you would when brewing tea. Allow the willow and water to steep overnight.
