I have a living stone, and have had it for many years now. However, As far as I'm aware they are supposed to grow and spread over a pot (hence why they should be kept in shallow dish containers).
My problem: my lithops has never spread!
It flowers freely every year and new 'leaves' grow up from inside. However, only 1 pair of 'leaves' is ever present.
I water it by giving it a thorough soaking and letting it dry out (advice from the houseplant expert book). I water it less in winter, if at all.
What am I missing here? Can anyone shed any light on my my lithops does not spread and grow?
