|I have a neighbor with large patches of grass that totally lose their color in the fall and winter. Amazingly the color comes back in spring and summer. The patches seem to get bigger each year and I am afraid this will soon be in my yard. What is this, what can be done to stop it/treat it?
|I can't tell from your description whether the lawn is developing fungal spots or if the soil pH is wrong and the grass is not getting the nutrients it needs to remain green. Fungal diseases such as snow mold and powdery mildew signs include mycelium or fungal spores on the grass blades themselves. A magnifying glass can help. Or, you can ask your neighbor for a sample of the grass so you can take it into your local cooperative extension office for positive diagnosis. A check under the microscope can positively identify the problem for you. Helpful folks at the extension office can provide control measures if it is a fungal disease.
