Here in the Pacific Northwest, moss grows on pretty much everything. We had a pretty heavy pollen season this spring. DH hasn't washed the Suburban for awhile, so now the pollen has moss growing on it. Our roofs have to have the moss removed each year, and it grows on sidewalks and driveways. The old wive's tale is that you can tell which way is north by finding the mossy side of trees if you're lost in the woods. Except the trees often have moss all the way around.
I live in a little clearing in the woods, and the only way I have been able to get healthy grass to grow is to use lime to make life unpleasant for moss, and to keep the grass well-fertilized and healthy. If the grass gets too long, it stays damp all the time at the soil surface and the moss really goes wild. And if possible, remove anything that shades the grass. Though your neighbor may resist taking down their 100' fir trees so you can grow better grass .
it's not the edge of the earth, but you can see it from here
aaahh.... up he'ah you *can* tell North by the moss on the trees.
Now I get it. I was trying to picture moss out in the open... in my pastures I have a big slab of granite (well, the whole mountain is a big slab of granite, but the big flat slab is the only place there's no soil) that is the only place--other than some trees--the moss grows up here.
I could send you some Arctic cold, would that help?
