What a Summer! Drought-like conditions in July followed by rain, rain and more rain in August. Unfortunately, those are perfect conditions for infectious lawn diseases. Honestly, we haven't seen this type of disease-favorable weather in 10 years! Think of it as the "perfect storm" for lawn disease. Diseases like Brown Patch, Dollar Spot, Pythium Blight, Leaf Spot Diseases and the appearance of symptoms of Summer Patch and Necrotic Ring Spot. While temperature and moisture can bring on these diseases, there are other factors that take over once the disease becomes established.
Also, some grasses are more affected than others by lawn disease, but all lawns are affected.
Keep in mind that if you water at the wrong time of day, you could be making a bad situation even worse. The worst time to water is between 6-9pm. Watering at that time only encourages lawn disease. It could mean the difference between a mild symptoms and a severe outbreak. To help prevent lawn disease, think deep infrequent daytime watering, not light frequent watering.
The best thing you can do for your lawn now is not to apply fungicides every two weeks, but rather to build up a healthy population of microbes in your soil that will fight the bad guys. Over time, our applications help to do just that.
