Welcome to the summer in Richmond. Now that the hot, humid weather is here we are going to start to see Brown Patch forming around the area. Our organic blend helps your lawn fight against brown patch but when the environmental factors are perfect we might see some breakthrough.
Brown patch is most severe during extended periods of hot, humid weather. The disease can begin to develop when night temperatures exceed 60°F, but is most severe when the daytime and nighttime temperatures add up to 150, respectively. The turfgrass leaves must be continuously wet for at least 10 to 12 hours for the brown patch fungus to infect. Poor soil drainage, lack of air movement, shade, cloudy weather, dew, over-watering, and watering in late afternoon contribute extended leaf wetness and increased disease susceptibility.
The symptoms of brown patch vary according to mowing height. In landscape situations, brown patch appears as roughly circular patches that are brown, tan, or yellow in color and range from 6” to several feet in diameter. The affected leaves typically remain upright, and lesions are evident on the leaves that are tan in color and irregular in shape with a dark brown border.
Please Remember the following guidelines to keep Brown Patch to a minimum:
- Keep your mowing height around 4 inches for Tall Fescue Lawns
- Make sure your mower blade is nice and sharp to avoid stressing the plants
- Water deep and infrequent, avoid watering in the afternoon and at night
