Caused by <em>Clarireedia <\/em>fungi, it<em> <\/em>spreads through wind, water, equipment, and foot traffic, infecting all warm- and cool-season grasses.<\/p>    <p class=\"wp-block-paragraph\">It creates circular patches of bleached grass 1-5 inches wide that grow and merge and can infect 90% of the grass if left untreated. The good news? Our experts explain that it rarely kills the grass permanently, and it\u2019s manageable if you understand what dollar spot is and what helps it thrive.<\/p>   <div

Georgia<\/figcaption><\/figure>    <p class=\"wp-block-paragraph\">The three main signs of dollar spot fungus to always look for are:<\/p>    <ol class=\"wp-block-list\"> <li><strong>Circular, straw-colored patches<\/strong> 1-5 inches wide with sunken centers<\/li>    <li><strong>Tan leaf lesions <\/strong>with reddish-brown margins forming from the blade tip downward&nbsp;<\/li>    <li><strong>White cottony mycelium<\/strong> visible on the grass during morning dew<\/li> <\/ol>    <p class=\"wp-block-paragraph\"><strong>Mowing height affects appearance: <\/strong>On closely cut grass, dollar spot disease appears as well-defined, round patches about 1-2 inches wide, while in tall grass, it creates larger, more irregular spots.&nbsp;<\/p>    <p class=\"wp-block-paragraph\">Professor and Extension Plant Pathologist Alfredo Martinez-Espinoza from the University of Georgia explains that the name <em>dollar spot<\/em> is derived from the small, circular patches that resemble silver dollars.<\/p>    <h3 class=\"wp-block-heading\" id=\"2-advanced-dollar-spot-symptoms\">Advanced Dollar Spot Symptoms<\/h3>    <p class=\"wp-block-paragraph\">As the disease spreads, small patches join together into larger areas of thinned, stunted grass, often invaded by weeds.<\/p>    <p class=\"wp-block-paragraph\">&#8220;If left unmanaged, dollar spot can affect entire turfgrass swards,&#8221; says Martinez-Espinoza.<\/p>    <p class=\"wp-block-paragraph\">In severe cases, the grass can die off completely, leaving you with patches of bare soil.&nbsp;<\/p>    <h3 class=\"wp-block-heading\" id=\"3-dollar-spot-vs-similar-diseases\">Dollar Spot vs. Similar Diseases<\/h3>    <p class=\"wp-block-paragraph\">Dollar spot patches can look a lot
