Select a well-shaded area that does not receive direct sunlight during the hottest parts of the day. An east-facing hillside or an area shaded by trees is best. Moss requires moderate to heavy shading to survive.
Amend the soil to a pH balance between 5.0 and 5.5. To do this, mix water with a sulfur powder and place it in a spray bottle. Use a litmus-testing strip to test the pH balance of the mixture to ensure it meets the required pH balance. Spray the soil with the liquid before transplanting the moss.
Transplant the moss to the area where you will propagate it. Use a spade or shovel to lift the moss off the surface it is on and place it onto the new surface. Lift as much of the dirt bed as possible with the transplant. Place the transplanted moss directly in the center of the prepared surface.
Moisten the moss and the surrounding dirt with water for at least the first three weeks after transplanting. Use a hose with a misting spray head. Do not saturate the moss to where it rots, simply keep it moist.
