Glad to share info, hopefully as generously as it's been shared with me! I know you do so much of the same.
That's funny and cool that you would say Feb because that's probably when I did the cuttings though it could have been early March, definitely a few weeks before plants went back outside. I'm not surprised to hear about a cutting rotting in water, but sorry that happened. The advice I've always read and used for taking succulent cuttings is to let the cut dry/heal/callous (at least overnight) so pathogens are much less likely to cause rot.
