The moss path has just happened.
I would have liked to put down pavers but in early spring, a few years ago, I noticed that moss was growing on the compacted path. It does need a bit of water in the hottest part of the summer but for the most part it is self sustaining. I love anything green in the garden. Even in the winter....brush off the pine needles and you have a green walkway. These photos were taken in July.....probably the least "mossy" month of the year.
