My poor cuttings really have been through a lot. Many rooted, rotted, grew leaves, dropped them, re-rooted, etc. I had three in perlite that were beautiful....dozens of roots, several leaves, only to completely die when I watered them a tiny bit. Amazingly, 2 of them have since rerooted! Sadly, the ones that took forever to root were the lucky ones, because they had to deal with my mistakes less. They may be fragile...but they're truly hard to actually kill.
