How to Deal with Common Lawn Diseases

Thankfully, most homeowners don’t have much to worry about when it comes to lawn diseases. That is, as long as you maintain the lawn properly.

Taking care of your lawn is somewhat harder to do in the heat and humidity of summer. After all, whenever you go outside to enjoy the sunshine, it’s probably not a motivator to do some heavy yard work. Thankfully, most homeowners don’t have much to worry about when it comes to lawn diseases. That is, as long as you maintain the lawn properly

Brown Patch 

If you see circular patches in your yard, then it might be the first signs of brown patch manifesting. They are typically brownish-yellow and start out small, often about six inches wide. But they can also be several feet in diameter as well. Ryegrass and tall fescue are the most vulnerable. St. Augustine and Zoysia can also be affected by this disease. It’s most commonly seen during long periods of heat and humidity when nighttime temperatures linger above 68 degrees Fahrenheit. 

Powdery Mildew 

Powdery mildew is another common type of lawn disease. It’s a fungus and spawns different species depending on the type of plant that it infects. Cool-season grasses are the most vulnerable. If you have Kentucky bluegrass then you will need to be on guard. Most of the time, it appears in the shade on cloudy days or days that are mostly overcast. So if you notice strange white dust on the leaf blades, then more likely than not, it is the first stage of powdery mildew developing.  

Red Thread 

Have you seen pink or red webbing or thread on your lawn? This is yet another type of lawn disease. Sometimes, lawn diseases can be very subtle; other times, they are more obvious. Unfortunately, if there isn’t enough nitrogen in the soil, then your lawn will begin to develop red thread disease. It’s not all that harmful, but it is a good reminder to fertilize your lawn again. 

Snow Mold 

Under ordinary circumstances, you won’t have to worry about snow mold during this time of year. It’s usually seen in the early spring once the winter snow has begun to melt. Gray snow mold is also called Typhula blight, while pink snow mold is called the Fusarium patch. 

Fairy Ring 

Lastly, let’s talk about fairy rings. They typically develop in grassy areas or in forests. They gather in circles and can grow to be over 30 feet in diameter. You’ll see three types of fairy rings: darker green flushes by dying grass and mushrooms; a darkened green ring paired with the growth of mushrooms; and then only mushrooms.  They aren’t very damaging, but the problem is that they are extremely stubborn and difficult to remove.
