Most lawn diseases are caused by fungi, although grass species vary in their
susceptibility to particular diseases. Other factors affecting disease
development include the overall health of the lawn, prevalence of certain
diseases in the geographic area, weather and seasonal conditions, and lawn
maintenance practices.
Although their causes, symptoms, and treatments may vary, basics such as proper
mowing and watering can help bolster your lawn's resistance to disease. Here's
an overview of the diseases that could be invading and damaging your landscape,
provided by the Lawn and Landscape Institute of TruGreen.
