Le succulente sono dormienti in estate o in inverno e questo può portare alla frustrazione della propagazione. Le popolari echeveria e lithops sono coltivatori estivi che si riposano nella parte più calda dell'estate e di nuovo nel freddo dell'inverno. Crassula (include la pianta di giada), haworthia e sedum se la prendono comoda nel caldo e giocano nel freddo dell'inverno. Quindi determina se quello che stai percependo come un fallimento è in realtà una radicazione lenta o assente o una nuova crescita in dormienza.

Yay!! I love this post so much already! Ok here we go, sorry for the excessive amount of info…

1. Not all succulents can be propagated easily. Some species (haworthias, aloes, etc) do NOT propagate by a leaf. They CAN be propagated, but usually (9/10 times) you get more by being patient and waiting for pups (little babies) to pop up on the sides. Wait a year or so and you should have some. There's often a lot of them, too, so be prepared.
2. Ok so if your succulent can be propagated by a leaf(Echeveria, sempervivum, etc.), there’s some rules. Make sure that your leaf is fully intact. The curved bit at the end needs to be intact, especially. That’s the important part. Remove leaves by gently wiggling them, and doing a bit of twisting. Some leaves might break. Throw them away, they won’t propagate. If you’re having trouble, search for some YouTube videos for help.
3. Now you have to wait. Set the leaves on a paper towel and wait for them to callous. The end but that’s kinda curved (the part that attaches the leaf to the stem) should get dry and maybe turn brown a bit. Some leaves might get a bit wrinkly, that’s fine.
4. When they’ve calloused, set them on some succulent/cactus soil. DONT water them. Trust me. Wait another week or so before watering, and ONLY water the ends. ONLY the ends. Say it with me. ONLY THE ENDS. Otherwise the leaves will rot and be garbage.
5. Roots can take a long time to sprout. Some grow roots in days. Others take weeks. Jade plants are notoriously slow growers, so I’d recommend propagating visit cutting for those (google it, this post is already too long)
6. When little roots grow, water them more frequently, like once or twice a day. Or mist them. Either works
7. Now you wait! Keep up your little watering routine (don’t need to be obsessive about it, though. They’re succulents) Eventually, baby plants will form. If you keep them in a small pot, they’re going to stay that size. Put them in a big pot, and they’ll grow bigger. So if you get frustrated that you’re plants aren’t growing, and they’re jammed in a little container, or in a shallow tray, move them to a bigger pot and they’ll grow. But to start, a terracotta tray, the kind you put under a pot, works perfectly for propagating.
8. One last piece of advice. You need to tinker with this. Based on the humidity, season, and climate you are in, not everything I said will work for you. So don’t feel bad about experimenting!! Have a lot of fun, and be ready to deal with way too many baby succulents. They were super cute, but are rather annoying now. I’ve given some to all my friends and family, so now I’m stuck with like twelve of the same succulents that I don’t really want.

Best of luck!
