Hello All!

This is my first post but I am a long-time observer. I now have an issue and need your expertise!

I got this echeveria (left) last spring and it has since become etiolated.

I beheaded it a week or two ago and the stem shriveled and turned black. So, I cut that part off and stuck it in some water for a few days because I had heard that that would work. When I removed it from the water, the stem again shriveled and turned black over night. I put it back in the water and I have no idea how to prevent this from happening again.

This is all that is left. Please help me and my plant! Thanks in advance!
