Different species of algae have different pH requirements for establishment, and this is important in the control of algae. Algae are found throughout the United States and Canada. Algae, like moss , can out-compete turf in certain growing conditions. The conditions that favor the algae must be altered to encourage good turf growth. Algae can develop very quickly during extended periods of overcast warm rainy weather.
Aeration helps the turf in compacted soils and also allows the surface to drain better.
Avoid frequent shallow watering. During establishment of new turf, watering should be monitored. The frequent watering needed to germinate seed can encourage the establishment of algae. Good air movement is also important and fans may be needed in certain conditions to enhance air movement across the soil surface. The pH of the soil should also be checked.
