Rooting hormone is a product that contains chemicals that stimulate root growth in plant cuttings. These chemicals are synthetic versions of auxin, a natural plant hormone that regulates plant development and growth. Rooting hormone can be found in different forms, such as powder, liquid, or gel. Rooting hormone is not essential for all types of cuttings, but it can improve the success rate and the quality of roots for some plants, especially those with woody stems. Rooting hormone can also help the cuttings to develop faster and stronger than those without it. To use rooting hormone, the bottom part of the cutting should be moistened and dipped into the product before planting in a suitable medium.
