Overview
Although algae do not infect turfgrass directly, they are highly invasive and out-compete grasses for space and nutrients. Algal scum can be a chronic problem, especially on turf with poor air circulation and compacted soils in wet or shaded areas. Algal growth is encouraged by extended periods of rainy, overcast, and warm weather. During wet conditions, a slimy algal coating forms on the soil surface in less-dense sections of turf. These algal scums slow water infiltration, keep soil surface wet for extended periods of time, and impede oxygen movement into-and toxic gas diffusion out of-soils. (2 pages)
