I've tried for well over 10 years. I kill every single one. They either rot or shrivel. I have about 10 pieces all over the yard trying again. The only one surviving (so far) is in an open terrarium in the house. The other terrarium one fell apart when I touched it yesterday. They are supposed to be fool proof according to everything I've ever read. It is DRIVING ME CRAZY. Is there a secret I do not know?
