It's kind of mind boggling to read about struggles with moss. It's so very rare to see it here.
In SoCal it's dry nearly always -- so no moss. Would be doomed any way because we are sitting on limestone.
We certainly have our problems, just not that one. Interesting the regional differences. One of the problems we do have is the one Carl mentioned the other day -- shorty irises. He said it's due to spells of hot weather. Makes sense -- and I'm glad to finally have an explanation.
