One of the first important things I learned about moss is should you find it growing on your roof, you need a new roof. After that, we learned we needed siding, fencing, drainage, a sump and a pump, as well as new pipes from the house to the cesspool. Gutters, too.
Speaking of moss, the Pileated Woodpecker loves this tree. It’s full of boring insects and covered with moss. A lot of insects live in the moss. The birds love it, the trees don’t seem to mind it, though this particular tree is pretty much dead. But birds love dead trees even more than living ones.
There’s moss on most of our oak trees. Supposedly moss grows on the north side of a tree, but no one told the moss or the tree. So as far as I can tell, moss grows wherever it wants.
