According to SFGate Home Guides, gardeners landscape a yard with Scottish moss by using it as ground cover, as a backdrop to early spring flowers, around the edges of water features and in shady spots. Small plugs of the moss should be planted in a grid with 6 to 8 inches between each plug. The moss then fills in empty spaces as it grows and needs to be watered well.
Scottish moss can be found in garden centers or nurseries. Gardeners need only trowel to effectively plant the moss. Scottish moss placed around early spring flowers, such as daffodils, tulips and hyacinths, provides a lovely backdrop to the plants at a time of year where very little green is showing. If planted in shady spots in a yard, the moss can grow to fill out the areas where grass does not grow well. For this reason, it makes great ground cover beneath bushes and shrubs. Scottish moss im a rock garden provides a backdrop for other plants, fills in the crevices of rocks and helps to prevent soil erosion. Scottish moss is a great plant to place around edges of water features, especially ponds and waterfalls, because it thrives in moisture.
