I hope that this does not sound like a lame question for UBC but I am down in central California and there are no such things as moss lined forest floors or even moss covered tree branches in these here parts-at least none that I have found-not counting the microscopic species-I even have a tiny moss growing in the cracks of my concrete driveway but it is not Polytrichum or any of the very cool larger mosses that I enjoyed seeing in my brief sojourn up in northern California. Fortunately a friend sent me some mosses from Washington and I am growing them in pots and am always on the outlook for more culture information to help me improve my culture. It is all guesswork but I seem to be guessing fairly well. I hope to be putting up a web journal on them at some point later this year (?) on my website. But in the meantime if there are any moss growers that read this post please reply and let me know what is happening in your culture! Thanks.
