Moss Pathway: What materials are needed and how to construct?
I would like to construct a 150' foot path around my garden. I will use fieldstones as stepping stones, surrounding it with substrate.
I think I'd like to develop it as moss feature path; as opposed to pebbles or woodchips. It's in partial shade and would receive sufficient watering.
So far, all I've done is trench out the 150'-length path at a width of 18" and a depth of 6". I also placed a layer of epdm rubber liner at the bottom of the entire future trail as I had excess from constructing a garden pond; this will be better than landscaping fabric, and will help slow drainage a slight bit. The sides are not lined, so not completely.
I'd like to use the least amount of materials possible, but use what is practical and useful for sure. My idea is this:
ruber liner at bottom, then a 2" layer of clay (backfilled from when I trenched the trail), then a 2" layer of crushed gravel, then a 1" layer of woodchips. When the woodchips start to break down in about a year, I'd like to introduce moss (blender, etc.) to the upper layer. After the woodchip layer breaks down, it will likely leave the crushed rocks exposed enough for moss to colonize. The purpose of the clay is to trap some moisture and to enable me to plant a few low-growing perennials (strawberries, ligonberries, blue-eyed grass, moss phlox, and Silene caroliniana), intermittendly placed thoroughout the trail, in between the sequence of field stones.
Should I be using more/less material(s); how about a small amount of sand, pea gravel, etc?
