SUCCULENTS THAT YOU CAN'T PROPAGATE FROM LEAVES.
I am SO SICK of people saying “I’ve never had luck propagating aloe from leaves, but let me know if it works for you” or “you can propagate any succulent from a leaf or a bit of stem” because YOU CAN’T.
These are all plants that will never produce a new plant from a leaf. Ever. And there are probably others I’m missing. (Gasteria?)
Aloe, agave, and haworthia will both produce “pups.” Small plants that grow from the stem or from runners the mother plant sends out in the soil. If you pull a leaf off and lay it on dirt, you’ll have a dead leaf.
You can also behead an aloe, leave the stem, and new babies will grow all around the chopped stem.
I believe aeoniums are similar in their offshoots, but I don’t know off the top of my head.
Sempervivum put out oodles of baby plants. Cut one off, stick it in dirt, boom, you have another plant. Individual leaves won’t do anything but die.
If a leaf is attached to the stem in a dot shape; like graptopetalum, echeveria, sedum, pachyphytum, and all the hybrids and cross breeds; you can pull off a leaf and the leaf will create a new plant. If the base of the leaf creates a line or wraps all the way around the stem like aloes, you need the stem or runners in order to propagate the plant.
Everybody got it?
YOU CAN’T PROPAGATE NEW ALOE PLANTS FROM LEAVES. EVER. WITH ANY METHOD.
