I am not sure what is going on with this Alluaudia. It seems to be having issues.
That’s not good. I don’t know what it is. I would isolate the plant first. Then try dipping a paintbrush in rubbing alcohol and lightly rubbing to see what happens. But since I don’t know what it is, I can’t really help.
I’ll post it on the blog tomorrow and see if we get any responses there.
