Hello Im new here Just want to say hello.
I read the lithop question, I collect too, fine specimens there, I see too much water, this make them grow up and out. Not enough sun will do this as well. These as you are aware are from deserts and they are used to being treated as rocks the name " Living Stones" however will adapt to your life style as well. I live on the coast and aside from a bit of winter cover from frost n rain, they are great. I have my baby toes that was wet for 2 or 3 months back in behind things , man I almost lost it. But is fine now. If you would like more info on these I can help, I have many of these. Also This plant drinks all year waiting for hibernation, the months of aug thru sept, its hibernating so water every two weeks or when you can see its all the way dry where soil pulls. If you give to much water as well the tops will crack and split causing scars to your babies....I think by looking your doing a great job. lithops are hard to care for, I lost many , however remember that less water for these is way better even if it hurts you.... hope I helped...Lori
