Brown Or Large Patches In Your Lawn This Summer? It Might Be Disease!
Brown patches are quite common during long, hot summers – and usually, a few brown patches are nothing to worry about. Brown grass is simply dormant, and when the weather cools down, it will usually spring back up – happy and healthy!
However, if your lawn is developing brown or bare patches despite proper nutrition, hydration, and care, this could be a sign of a dangerous disease caused by Rhizoctonia solani, a widespread, pathogenic plant fungus that can cause serious harm to your grass.
In this article, O’Neill Landscapes will help you understand this disease that’s common to Georgia, and provide you with advice on how to fight back against disease, and restore your lawn to health.
Identifying Rhizoctonia Solani Brown And Large Patches
All cool and warm-season turfgrasses are susceptible to infestation by Rhizoctonia Solani – so it’s key that you’re able to recognize the symptoms of this disease early, before it progresses too far.
Brown patch is common on cool-season turfgrass, while large patch refers to the same infestation, which can occur in warm-season turfgrasses in the late spring, summer, and early fall.
Typically, Rhizoctonia Solani thrives in humid environments where daily temperatures exceed 80° during the day, and don’t fall below 60° at night – so Atlanta summers can put your grass in danger. Here are some common signs to look out for:
Rings/patches of blighted grass 5 inches – 10ft in diameter
Leaf spots or “smoke rings” – thin, brown borders around disease patches (common in early mornings)
Wide-bladed grass will have pronounced brown “splotches” and discoloration on the blades, with tan centers and dark brown/black margins
Rotted leaf sheaths are common near the base of warm-weather grasses
Cobweb-like growths in grass indicate the presence of the Rhizoctonia Solani mycelium, and are a certain sign of infestation
If you have one or more of these symptoms of infestation, you’re likely dealing with brown or large patch disease – and you should take the appropriate steps to solve your issue.
Managing Brown And Large Patch Disease
There are quite a few steps you can take to reduce the effects of Rhizoctonia Solani, and restore your grass to health. Here are a few tips:
Improve drainage to reduce soil moisture saturation
Increase the height of your mowing cuts as much as possible
Bag and remove clippings from infested areas – otherwise they may spread the disease to healthy grass
Fungicides can be applied by professional landscaping companies like O’Neill Landscapes. However, these are not commercially available for consumers – contact a professional.
Reduce moisture as much as possible in infected areas. Remove shade if possible, remove thatching, remove dew from turf early in the day, and try to allow for plenty of air circulation.
Large patch and brown patch require large amounts of moisture to survive – so reducing the moisture available in infected patches can allow you to fight the disease.
