Environmentally Safe Way to Remove Moss
Botanically, mosses are classified under non-vascular plants (i.e. plants that do not produce flowers or seeds and have no internal system for water transportation). These soft plants are usually very tiny with an average height of 0.4 to 4 inches. With a velvety feel, mosses might look beautiful on concrete or other surface. However, their slippery characteristic may pose a hazard, especially on walking paths. Moss growth on roofs downgrades the life of a roof covering and moss in a natural lawn indicates that the turf is unhealthy. While there are various conventional ways to uproot moss, there is always a safe way to remove moss without chemicals from lawns and roofs.
When moss grows on a roof surface, it absorbs moisture and holds it longer than areas that don’t contain moss. This is particularly true in roofs made from wood and asphalt shingles. Because moss holds water on the roof surface for a longer duration it gradually decreases the life of roof shingles and speeds up their demise.
Natural lawns with mosses indicate that that the grass is unhealthy. Moss in the lawn hampers the growth of grass by creating unfavorable conditions such as soil compaction, decreased fertility and poor drainage of water. It also does not allow the sun’s rays to reach grass. To remove moss from lawns and roofs it is very important to follow the easy, environmentally friendly tips below.

Controlling Moss Growth on Lawns
Using chemicals to remove moss growth on lawns can adversely affect the grass. The easiest way to remove moss without chemicals is to prevent moss from forming by creating an unfavorable environment. Nitrogen-deficient grass invites the growth of moss. Using natural organic fertilizers such as manure, slurry, peat and brassin, nutrients and minerals can assure a healthy lawn. Applying natural fertilizers slowly releases nutrients and ensures the soil stays healthy and prevents moss from growing. However, if there’s already an infiltration, you can use a rake to remove moss.
