null on Plant-Maturation
Quick answer
If your Plant-Maturation has null, the most likely cause is: Plant maturity profoundly affects adventitious rooting ability. Juvenile plants (seedlings that cannot yet flower) root easily because they retain high natural auxin concentrations and have plastidic cell walls. As plants mature and enter the reproductive phase, rooting capacity declines sharply — mature cuttings may have 0% rooting where juvenile cuttings achieve 80%+.
Start here:
- 1. Select stock plants in juvenile phase (not yet capable of flowering)
- 2. For mature specimens: prune heavily to stimulate juvenile sucker growth from the base

Plant maturity profoundly affects adventitious rooting ability.

How to reverse null on Plant-Maturation
- 1
Select stock plants in juvenile phase (not yet capable of flowering)
- 2
For mature specimens: prune heavily to stimulate juvenile sucker growth from the base
- 3
Take cuttings from the youngest stems — basal growth is most juvenile
- 4
Serial grafting mature scions onto juvenile rootstocks can restore rooting ability
- 5
For species that lose rooting capacity with age: use root cuttings which produce juvenile shoots
- 6
Avoid taking cuttings from plants that are flowering or fruiting — diverts energy away from rooting
Keep null off this Plant-Maturation
Propagate from seedlings or young plants when possible; prune mature plants to force juvenile regrowth; use root cuttings or stooling to recover juvenile characteristics.
