Hormones for Better Rooting

To improve the chances of success when propagating plants by cuttings, especially those whose woody stems which pose a particular challenge, the use of a rooting hormone is proving to be an extremely effective technique. This stimulating substance can be applied simply but precisely to the lower end of the stem. Two commonly used methods are to use a cotton bud soaked in the hormone, or to immerse the affected part directly in a container containing the hormone. It is crucial, however, to shake the cutting gently after application to remove any excess hormone, as a surplus could paradoxically hinder the desired root development.

Once the hormone has been correctly applied, the cutting should be planted in a pot filled with moistened potting soil. To create an environment conducive to rooting, the practice of growing the cutting in a smothered environment is highly recommended. This method involves covering the cutting with a transparent plastic bag or specific dome, creating a warm, humid atmosphere that stimulates root growth. The appearance of new leaves on the cutting is a reliable indicator of rooting success. At this stage, the plastic protection can be removed, allowing the young plant to gradually acclimatize to a less confined environment.

Willow Water

For those who prefer a more natural approach or wish to experiment with homemade solutions, making a rooting hormone from willow stems represents an ecological and economical alternative. The process is surprisingly simple: simply crush a few fresh willow branches lightly with a hammer to release the active substances, then leave them to soak in water for between 24 and 72 hours. The enriched water, commonly known as “willow water”, becomes a source of natural rooting hormones. Cuttings immersed in this preparation benefit from a stimulating environment that encourages the early appearance of roots. As soon as the first signs of rooting are visible, in the form of white or yellow nodules on the stem, the cuttings are ready to be transplanted into quality potting soil.

Whether you opt to use commercial rooting hormones or homemade willow-based preparations, these techniques considerably increase the chances of successful cuttings. Far from being complex, this propagation method opens the door to efficient multiplication of plants that are difficult to cut.

  1. Cottonwood water works like willow water. I have not compared the two though.

    I like the willow water method. The other root hormone always has a message on the package that it is not to be used on plants used for food or growing food like orange tree cuttings and others.
