OUCH! That's what my Mystery Mesemb had to say about its new leaf pair last week:
I simply took a very clean, sharp, small knife and cut away the old leaf that was not shrinking enough to let the new leaves grow. I was worried, but everything turned out to be fine, and the mystery mesemb is now healthy with new leaves growing freely, and fast!
Have you ever done mesemb leaf surgery? How did it turn out?
