What is Spring Dead Spot?

Varieties:  Bermuda and Zoysia

Spring Dead Spot is a fungus that can be identified by the appearance of circular patches from 6 inches to several feet in diameter. These patches remain dormant as the turf greens up in the spring and eventually die and collapse to the soil surface. The roots, stolons and rhizomes are dark and rotten in affected areas. The fungus patches recur in the same spot each year and increase in size by up to several inches each season. Recovery is very slow, taking the entire growing season in severe situations

The Spring Dead Spot patches prevent the uniformity of a lawn and frequently they’re invaded by weeds. If left unmanaged, this fungus becomes more severe as the years pass.

It attacks the plant during the fall and winter and doesn’t  directly kills it, but instead makes it more susceptible to freezing injury. As a result, Spring Dead Spot is most severe in the northern areas and usually after extremely cold winters.

Excessive nitrogen, potassium deficiencies, poor soil drainage, over-irrigation, excessive thatch accumulation, and soil compaction may encourage disease development.
