I Have Brown Spots In My Grass Shaped Like Circles

Brown Spots In The Lawn: Fungus And Disease Options

Chances are, thats brown patch disease. Brown patch can appear in lawns in early fall if its humid and temperatures are about 70 degrees and up.

Your lawn likely has brown patch if:

  • There are brown patches roughly shaped like circles that are up to several feet wide
  • In the center of the patch, the grass is green, creating a doughnut-like look

There are a few things you can do to relieve your grass of brown patch disease:

  • Only water your lawn if its dry. When you do water, plan to do it in the morning
  • Mow your lawn at the proper height and aerate your lawn if it has lots of thatcha layer of dead grass that builds up between the soil and live grass
  • Talk to your local arborist about a fungicide to treat brown patch

Keep It Under Control

The good news is that your turf can recover from brown patch. The bad news? You may have to wait until the active growing season to see an improvement in appearance. While a fungicide application can help prevent spread to other areas, spots that have rotted will need to regrow.

Meanwhile, steps should be taken to ensure youre not transferring the fungus to healthy parts of your lawn. Affected areas should not be mowed, as that could cause diseased clippings to deposit elsewhere, spreading the infection. You should also avoid walking over the area so your shoes dont transport the spores. Finally, its important to not apply fertilizer during an outbreak. Sure, youll feed your lawn, but youll also feed the fungus, too.

Because brown or yellow spots can be the result of a number of causes, its important to have your lawn assessed by an experienced landscape professional. If brown patch is confirmed, proper treatment is critical. Self-diagnosis and treatment could make the problem worse.

Three Most Common Diseases Causing Brown Patches On Lawn

Most of the summer lawn diseases that attack tall fescue and Kentucky bluegrass common in Midwest lawns prefer warm/hot and humid weather. The best conditions for brown patch or Pythium disease growth are daytime temperatures between 80 and 95 degrees F, night-time temps around 65 to 70 degrees F, and high humidity. High summer temperatures combined with late afternoon showers every day in late May through July can be a recipe for disaster for lawns.

Brown patch disease appears as circular patches in your lawn.

Brown patch is a common lawn disease found in all cool-season grasses in the U.S. caused by a fungus called Rhizoctonia solani. It appears as brownish-yellow, irregular circular patches that range from 6 inches to several feet in diameter. Brown patch begins to grow when temperatures reach 65 degrees F, but it grows fastest when temperatures reach 80 to 85 degrees F and there is high humidity.

The diseased leaves usually remain standing, and close examination shows tan, irregularly-shaped lesions on the leaves with a dark brown border.

2. What Is Pythium Blight Disease?

Pythium blight appears suddenly and can kill your lawn.

Cultural Management: Preventing Brown Patch Lawn Disease

Since high levels of fast release nitrogen increase disease activity, Spring-Green uses a correct blend of fertilizers for lawn fertilizing during the warmer months. Mow less frequently during periods of hot and humid weather, this reduces stress and limits the movement of grass disease by being carried on your feet or mower. If possible, increase light and air penetration, or movement, by pruning overhanging trees and shrubs. During cooler seasons, open up the thatch layer with power core aeration. If these cultural cures fail, a preventative fungicide lawn treatment program may have to be applied to control this most damaging of lawn diseases.

Foot Traffic And Forgotten Things

Sometimes its our own doing that results in spots appearing in your yard. Its nice being outdoors once in a while, especially during a warm sunny day where your family can gather, play, and have fun on your lawn. Another instance includes having a barbeque over the weekend or having a birthday party with bouncy castles and inflatable pools.

However, it can potentially cause brown patches on your lawn. You might be left with dead and dying patches of grass underneath the bouncy castle, inflatable pool, tables, chairs, etc. Stepping your grass repeatedly and even accidentally leaving out your hose in the yard can damage your grass. Other than that, buried and forgotten debris also causes brown spots.

Final Thoughts

Upon knowing what causes the brown spots in your lawn, you can easily understand how to treat them and restore your lawn into its former glory. You can find the proper treatment method for the dead or dying grass after spending some time researching on the internet. However, when in doubt, you can always consult a professional.

Forgotten Toys Or Tools

Leaving items on your lawn even just for a day or two, but especially for longer periods of time, can create brown spots.

The item on the grass prevents that patch of grass from getting the sunlight, air, and water that it needs to thrive. This can cause a patch of grass to go dormant, such as in a drought situation.

However, if an item is left on the lawn for too long, such as a playset, then the grass underneath will ultimately die.

You can prevent this by picking up toys and tools off of the lawn at the end of each day.

Brown spots from temporary items will recover quickly on their own but spots that were covered for longer periods of time might benefit from using a patch and repair mixture like .

Diagnosing Brown Spots In The Lawn

When homeowners find brown spots in the lawn, they are quite commonly thought to be related to drought. Homeowners see that their lawn is turning brown in some areas and they automatically assume it must not be getting enough water.

While lack of water can certainly cause a lawn to brown, its by far not the only possible culprit of brown spots.

In fact, there are some reasons for brown spots in the lawn in which watering could make things worseparticularly lawn fungus.A big factor in diagnosing brown spots in the lawn will be what time of the year that it is. There are certain problems that will be more likely at certain times of the year. While oftentimes various problems can cause the same-looking brown spots, paying attention to the season will play a big role in determining whats going on.There can be a fair amount of detective work that goes into the diagnosis.

In addition to the time of the year, we might also look at which areas of the lawn are affected. For instance, ifs just one spot in the front of the yard, it could be that a neighbors dog is using that spot to go the bathroom. If it were a problem like a lawn fungus or even an insect, it would not just be a single spot that is affected.

How To Identify The Type Of Fungus On Your Grass

Brown Spots in the Lawn from Dog Urine, Fungus, Mowing

The fungal organism is in the soil. Right now. Every soil, everywhere. There are a variety of reasons why your neighbor may have brown spots in their lawn from disease and you dont. They may have a different species or variety of grass, different soil or moisture levels, or a different climate due to other natural or man-made landscapes.

There are three things to consider when trying to determine if a disease is causing the brown spots in your yard. It is very important to identify the specific type of disease. Correct identification is required before you can develop a treatment plan.

1. Identify the type of turfgrass

Its important to first know the type of turf species you have because different types of grass are more susceptible to different diseases as shown in a University of Purdue Extension article on turf disease identification. In the Midwest, the two most common types of cool-season grasses used in home lawns are tall fescue and Kentucky bluegrass. The most common diseases we see are brown patch, dollar spot, and pythium blight. But other diseases do show up in our region from time to time.

2. Observe the pathogen at work

3. Consider the environment

The environment is the third component of identification and time of year must be considered. In the Midwest locations of Ryan Lawn & Tree, the warm temperatures, high humidity and soil composition including fertility and pH all play a role in the growth of various lawn diseases.

Why Are Brown Spots In My Lawn: Insects

There are a lot of things that can cause brown spots in your lawn, which makes it hard to get rid of the unsightly splotches. One of the easier causes to identify, though, is insects. There are a handful of insects that do serious damage to home lawns every year, infesting turf throughout their life cycle and leaving brown patches in their wake.

One such pest is grubs, which are beetle larvae that live underground and feed on grass roots. The root damage prevents the grass from taking in the nutrients it needs, causing it to wilt and turn brown. You can check for a grub problem by pulling out a small section of grass. If it pulls out easily, that indicates root damage and could be a sign of grubs.

Another insect that causes brown spots is the billbug, a common but often misdiagnosed pest. Billbugs lay their eggs inside grass stems, where they hatch into legless larvae that feed on the plants from the inside out. Their damage weakens the grass so that it breaks off easily when pulled. Where the grass breaks off, you may notice insect excrement that looks like sawdust.

Chinch bugs are flying insects that damage lawns as both adults and nymphs, feeding on grass blades and extracting nutrients from the plants. They also inject a poison into the grass that turns it brown and can even kill it. Check for a chinch bug infestation by looking for the insects in the thatch layer of your lawn.

Can A Brown Lawn Be Saved

Generally, yes. If the lawn is brown because it has gone dormant, it will bounce back by itself and turn green again during its growing season. However, if your lawn has turned brown all over due to drought, there is no way to revive it.
