These types of questions come up regularly. You are not alone. That is why we have created a step-by-step plan:
1. Check which cultivars you want to propagate from cuttings.
2. Go to the rooting table to see if your cultivar(s) are listed.
3. Decide on the method you want to use.
4. If multiple concentrations are mentioned, check the quality of the cutting. Older cuttings require a higher concentration than young and freshly cut cuttings.
5. Are you using a cultivar that normally roots fairly easily, or is there a lot of failure? In the latter case, use a higher concentration.
6. Apply the rule of thumb: the more ligneous the cutting, the higher the concentration of rooting powder.
7. If the cutting is green and soft, make sure the concentration is not too high.
8. Always test on a small scale beforehand to determine whether the chosen concentration(s) are sufficiently effective under the cultivation and climate conditions at the nursery. This may vary from nursery to nursery.
9. If you have any questions about rooting cuttings, please contact your supplier or Rhizopon.
