I have seen a lot of videos on how to propagate an aloe with leaf cuttings. They usually let the leaf stand for a few days, then stuck it into wet soil.
It does not work for me - the leaf just starts to rot after a few weeks.
What I tried
- put leaf into soil, with and without rooting hormone
- put leaf into wet clay perlites
- wrap peroxide sterilized leaves into wet kitchen towel and foil
