I get news for you--you can not kill a mother-in-law's tongue. I know I have tried!!!!!
Our pot is behind the shade house getting very little sun and very little water and I do not think that there is any room left in that pot for soil. And it is very health.
Any one want any of it??? I need to repot soon (this is my DM's plant that she get from her late mother. A lot of the plant will go into the trash.
