Moss, Gotta Love the Moss...

Again, maybe I'm ignorant as to how difficult it is to lay moss (from what I've read it's not that hard), but I am swayed by a healthy looking layer over the soil of a Chinese Elm. I'm sorry but it just looks so lucious...

Somewhat interesting floating root feature too... I like the thickness of the trunk, wonder if there's an easy way of calculating the age of the tree without "chopping" it down and counting the rings...
