Yes, honey can be used as a natural alternative to rooting hormone for tree branches. Honey contains natural enzymes and antimicrobial properties that can help stimulate root growth and protect against fungal infections. To use honey as a rooting hormone, simply dip the cut end of the branch in honey before planting it in soil or water. This can increase the chances of successful root development. However, it's important to note that honey may not be as effective as commercial rooting hormone products, so results may vary.
