Sheet moss grows in northern North American forests where it is found on logs, rocks and other surfaces. Since it is found in a variety of places, it is known by a range of names such as carpet moss, log moss, rock moss and feather moss. These names describe some of the moss' qualities. It is flat, thick and can be harvested in sheets which makes it easy to transplant. The moss prefers slightly acidic soils, both loam or sand. It does well in areas with partial shade. Homeowners with shaded lawn areas use moss as a lawn alternative. Moss withstands light foot traffic and is quite comfortable below bare feet. It can also be used in shade gardens. Sheet moss' color ranges from bright green to yellow. It is hardy to USDA zones 5 through 7 and grows prolifically in cool, humid climates. Aside from lawns, moss is grown on green roofs to encourage energy conservation. It is used as a lining for hanging baskets, as a soil cover for terrariums, for arts and crafts and also for packing material. When harvested from forests or natural areas, the moss is peeled back in a sheet and can be dried before shipment. When it arrives to its destination the sheet is unfurled and laid out on a prepared surface free of competing weeds and grasses. Once situated, a moss lawn or ground cover requires little maintenance other than regular watering. However, if the lawn is sited in a naturally shaded and humid area there is little need for additional care. Your lawn will be green and verdant without the need of a lawn mower, fertilizers or chemical treatments. Most commercial moss originates in the Appalachian region or the Pacific Northwest. If your climate is similar then your moss should take hold without much trouble.
