Rooting Hormone Stimulates Growth

Many rooting hormone preparations also contain growth regulators and fungicides to protect the plant from disease.

Many gardeners use rooting hormone to propagate their plants. Cuttings are taken from a parent plant,
called a “clonal,” and rooted in a growing medium. The new plant will be identical genetically to the parent plant. Also called “adventitious rooting,” this method is commonly used by gardeners to create a row of the same plants or crops, sometimes for aesthetic purposes.

In this process, the immediate generation of new roots is essential, as the roots must carry water and
nutrients to the new plant. At the most critical stage in the cutting’s root development, the rooting hormone in the growing medium stimulates growth. This ensures the cutting’s survival. Many rooting hormone preparations also contain growth regulators and fungicides to protect the plant from disease.

The kind of hormone needed depends on the type of plant or crop to be grown. Many hormone
preparations are available for ornamental plants, and some are harmful if swallowed. Other startup
preparations consist only of a mixture of minerals and trace elements that support the survival of seedlings and transplants. These mixtures are safer and not harmful if swallowed.
