Dollar spot appears as small spots, approximately the size of a dollar coin, that are bleached-white or light tan in color. Dollar spot is encouraged by drought stress and leaf wetness and most often occurs June to October.
Adequate nitrogen fertilization will help prevent dollar spot, and will also encourage plants to recover quickly. Proper irrigation timing is also needed to balance these factors. Then lawn should be watered early in the morning (between 4am-7am), to keep leaf wetness periods as short as possible. Proper mowing is also very important, you should never cut more than 1/3 of the grass blade off at any time to avoid shocking the grass plant. Keep your lawn around 3” long to make sure your grass doesn’t start using its food reserves, which will impact how quickly it recovers.
