I have three mammillarias - hahniana, bocasana & matudae. The first two appear to be doing well (the tiny bocasana is flowering), but the matudae seems to be imploding. It looks like a slowly deflating balloon
.They were all bought about the same time, from the same store & were supplied by the same grower. Everything about their living conditions is identical, so I am at a loss as to what is happening to the matudae
. Should I just cut my losses & replace it?? As a newcomer, cactus
-wise, any advice would be greatly appreciated.
