Sorry, don't know where you're finding this stuff. Gasterias do NOT grow from cuttings. Just not gonna happen.

They CAN be propp'd from leaves, entire leaves gently plucked off the base of plant. I have done this myself, takes a long time (mine took 9 months to show new growth from a Gasteria leaf which was 8" long).

I doubt very much CUT or sectioned Gasteria leaves will work.

Why not just buy some plants? Or if you're intent on learning propp'g why not try species w/ greater likelihood of success. Examples might be Crassulas, Kalanchoes, Eches, Sedum, Graptos, Pachys, etc.

I tried and none rooted:(.

I've tried both. Leftmost in that photo will root and grow plantlings faster. by that I mean you'll feel it is rooted in about 4 months and in about a year you might see new growth. it depends on what species you are working with. Croucheri is the fastest, armstrongi is the slowest.

The rest of them will have to callous before you can stick them in a pot of pumice. Without the collar, it's going to be hit and miss but the odds of rooting increases if left alone.

Thanks for the link Rina, excellent viewing. I didn't know the term 'collar' but yes, I believe that will work. The leaf I rooted had the whole collar intact.

I gotta say I'm w/ the Pagan on this, they do best when left alone, really, they do.

All gasteria leaves in the picture will root. ALL of them. I have had experience growing gasteria from many differently sized sections of leaf, and as long as the leaf is not too small, a plant grows.

Really Garrett, hard to believe (not that I disbelieve you, but you know what I mean).

Got any pix of such oddities? Then again it might not show if inserted into mix.

I actually regretted experimenting with that, Garrett. It took a couple of years to get rid of all the plantlings I ended up with. One such G. croucheri leaf about 14 inches long grew three plantlings and was unwieldy so I cut off the parent leaf. At the end of summer, it had rooted where I left it so I planted that and it grew three more.
