When a cutting is removed from the parent plant, it will form roots under the effect of the hormone auxin, produced industrially as rooting hormone.
Rooting hormone is produced by all plants but not to the same extent. For example, some plants take root easily, while others take longer and have a lower success rate.
1. Put cuttings that root easily with your cuttings:
The easiest way is to put together plant cuttings that root easily with cuttings of the plant you wish to propagate.
You can put one or more willow or bramble stem cuttings or a bundle of mint sprigs in a glass of water and add your cuttings.
2. Bundle your cuttings:
All plants produce auxin. If you put several cuttings together in the same glass of water, they will profit from all the auxin produced by each of the cuttings.
3. Prepare willow water:
It is fairly easy to produce produce a natural rooting hormone solution in which to dip your cuttings:
- put several willow stems in water
- wait a few weeks: the water becomes viscous
- it is this viscous solution that can be used as rooting hormone: put it in a bottle and store in refrigerator
- use: dip the cutting in the solution before planting it in soil or add the solution to the water in which you place the cutting to root
Plants producing natural rooting hormone:
- Willow: any species of willow will do (weeping willow, white willow, curly willow…)
- Burl: any species (common blackberry, dewberry …)
- bunch of mint stems
- or any other plant you have that roots very quickly
