Answer: Moss tends to occur naturally in areas that are suited to it. Typically this would be shady and damp, possibly with compacted, low fertility, acidic soil. You may also find it growing on rocks or bricks. To encourage it, you can bring in moss that you find growing in a similar location under similar conditions. (There are many different kinds of moss, so this is important.) Transplant pieces of moss "sod" and keep them damp with a misting of water until they take. Or, you can mix the moss with an active or live cultured buttermilk and paint that mix onto a surface where you would like moss to grow. (Some gardeners use an old blender to mix them. The moss tends to have bits of grit in it so it may damage the blender.) Keep it damp and the moss should grow. Where it is well suited, moss should continue to spread on its own. In the meantime, stop doing things that would discourage moss. For instance, do not lime the area as one would for growing turf grass. I hope this helps.
