Common Lawn Diseases

When disease hits your lawn grasses, control can be difficult unless you know how to identify lawn and grass diseases and understand the causes behind them. Many common lawn and grass diseases have fungal problems at their source. Fortunately, proper lawn maintenance and care prevent and resolve most fungal lawn diseases. 

It’s good to know the basics about lawn diseases. Most lawn diseases are caused by a form of fungus. The fungi need to obtain energy as a means of feeding off of either dead organic matter (and convert the nutrients in dead organisms into energy) or find and take over a host plant.


Some common locations you will find fungi in your lawn will be under dead leaves, the shade or in excessive thatch.


Fungi spread through spores, which are easily transferred through wind, rain, mowing and simply walking through a fungi outbreak.
