Moss will happily grow where many other plants will not, like shade. Since moss will grow nearly anywhere and in any soil type (provided the pH is 5.0-6.0), they’re relatively easy to transplant from one part of the landscape to another. Spring or fall is the best time for planting moss, especially after it rains. Prepare the site by removing any grass or debris and raking the area smooth. Water it thoroughly and then place the moss, in patches, into the designated areas, pressing down firmly. You can also moisten the bottoms of the moss. There’s no need to keep them close together. Once it has taken hold, the moss will readily spread into one another, filling in any empty gaps. To help the pieces of moss stay in place, secure them with small twigs. Keep the area damp, but do not over water. The moss patches should begin to establish themselves within a month or so. Moss also propagates by spores so putting it in a blender with water or buttermilk for a minute or two and pouring it onto the area will also create healthy moss plants in about five weeks.
