I continued my repotting today. Two good ones, one of the younger adeniums with rot.
Somehow, however it seems to be coming back without my help. Something similar happened to the one I posted blooming the other day. The bad part dried out all on its own and now it's blooming.
I uprooted it, and will set it aside to dry and wait and see... it looks bad, but little leaves are sprouting. Should I pursue or give up on it?
