Moss and algae grow in areas of lawn where conditions are not suitable for turf grass. Generally moss will grow in an area which has an excess amount of moisture and stays moist throughout the day. These areas do not need to be shaded, however shade is usually present where moss grows. Other factors which contribute to the growth of moss are poor drainage, low soil fertility, compaction, and a large percentage of clay in the soil composition.

Many types of algae usually grow in areas with bare soil. The same factors such as shade, compaction, excessive moisture, and poor drainage contribute to the growth of algae.

Appearance of Lawn

The problem moss and algae create in a lawn is cosmetic. Moss gives the lawn a pale green color. It also competes with the turf grass and can gradually choke out the healthy grass. Once algae have control of a bare area of soil, it is very hard for turf grass to become established.

Cultural Control

Because moss and algae tend to grow in areas that are unfavorable for turf grass, it is necessary to make changes to the surroundings before grass can establish itself. One of the most important things to do is improve the drainage to alleviate excessive moisture. Both moss and algae dislike sunlight. Open up areas by pruning trees and shrubs to allow more light to enter the affected areas. Aerating will relieve soil compaction and help to dry out the soil. Using these corrective measures should go a long way to solving your moss and algae problems.
