I put mine into the soil, pushed in far enough that they stay upright. Spritzing occasionally is fine although I'm not sure they need it. Crassulas can take as long as two months to sprout. The main point is to leave them alone-don't pull them out to see if anythings happening.

Agreed.

Set and forget 8D

I also put my leaves, business end down into potting medium as described above.

I use C&S or bark fines mixed with perlite, however, I never water them.

The most convenient thing I've found, is those teeny little seed starter trays with multiple cells. I like them, because they get to grow undisturbed until they are a good reliable size.

One or a few leaves per cell. I check once a week and if and when one leaf shrivels, rots or does not appear viable for some reason, I pull and & toss.

I keep it outside in a bright shady spot & as long as the leaves still look plump and as if they are still on the plant, I don't water. It only draws my attention when leaves start to look dessicated, upon closer inspection, I'll see teeny plantlets, at that point, I may water.

It's kind of a game of numbers. Propagate more than you plan to keep, that way you forget about the failures and only focus on successes.

Out of 2 dozen leaves, 16 may become plantlets, of that 16, 11 may actually continue on to become more than just a wee little rosette or flourish of leaves 8D

I propagated all the sunburned leaves =D

You said that some leaves were cut off. Did you cut off a single leaf, (leaving the end of the leaf attached to the plant) or did you cut a branch off of the plant with leaves on it? If the former, I believe you need an intact leaf to propagate. You'll get plants from the leaves you plucked off, though.

Egg cartons work great, too.

I started these on 8/3 from a Pachyveria pruning session due to etiolation. I used Perlite and Turface fines

Lately I've been lazy and just toss leaves in a plastic dish. Doesn't seem to matter to them either way. =)

Thanks everyone for your responses.

Amynoacids, I cut some leaves off the branch but I cut them very close to where they sprout from the branch. Does it affect the growth?
