The rooting agent most commonly used in gardening is rooting hormone, which often contains auxins, a type of plant hormone that promotes root development. Gardeners apply rooting hormones to cuttings of plants to encourage them to produce roots more quickly than they would naturally. It comes in various forms, including powders, liquids, and gels. The use of rooting hormone can significantly increase the success rate of propagating plants from cuttings, enabling gardeners to create new plants with desirable traits. Utilizing this agent is particularly effective for species that are challenging to root on their own.
