St. Augustine grass is a much loved warm-season turf grass here in Texas. Not only is it lush and thick, but it also grows very rapidly, helping it outcompete weeds. As hardy as it seems, St. Augustine grass can still suffer from stress and diseases such as brown patch.
Brown patch is a lawn disease caused by the Rhizoctonia fungus. It usually appears when grass has been wet for an extended period of time or when temperatures drop below 68 degrees. This lawn disease is common in early spring and late fall when wet grass doesn’t have enough daylight hours to dry.
Symptoms of brown patch appear as greyish brown rings that can ruin the appearance of your yard. As the fungus spreads, the infected grass may wither and die, allowing weeds to quickly take the space. Luckily there are steps you can take to prevent this fungus from appearing in the first place.
Because water is what helps the brown patch fungus grows, it’s important to follow a strict irrigation schedule. sIt’s important to avoid inadvertently harming your own grass. Watering should be done early in the morning to allow time for the grass to dry out. Remember, wet and cool conditions are what brown patch loves best.
Keeping your grass properly irrigated while also trying to avoid brown patch is a delicate balance. St. Augustine grass is a warm-season grass and should only be watered every 5-10 days or when it starts to show signs of drought.
Fertilizers don’t just make your grass look lush and green, but it also makes it tough and resistant to diseases. Knowing when to fertilize is very important when it comes to lawn disease. Do not fertilize in the late spring and early fall when brown patch is most common. Instead, fertilize in late spring or summer to avoid your lush grass from being targeted by brown patch.
Thatch buildup can be a breeding ground for brown patch. As layers of broken down leaves and grass clippings build up it creates the ideal moist conditions that lawn fungi needs to thrive. It also prevents water from soaking into the soil, creating even more problems for your yard. Core aeration can loosen up thatch and the soil to allow water and air to flow back into the ground to the roots of your grass.
St. Augustine is a fast growing grass so it’s important to keep it cut at the proper length. Keep things like sticks, leaves, and grass clippings out of your yard. These can all retain moisture under the grass, which can breed brown patch.
