Can Lawn Recover From Brown Patch? (My Experience)

Brown patch is a type of fungus that grows on the surface of your lawn. It’s also known as dollar spot or St. Augustine blight. Brown patch can affect all types of grasses, including bentgrass and Bermuda grass. 

The disease usually appears after periods of heavy rainfall or during times when temperatures are too high for your lawn to handle.

Brown patch fungus is a common lawn disease caused by various species of fungi.
The fungus thrives in hot and humid conditions, typically forming circular or irregular brown patches in the grass.
Prevention involves avoiding overwatering, ensuring good drainage, mowing at the right height, and reducing the nitrogen levels in the soil.
Treatment involves fungicides, proper watering, and fertilization, and in severe cases, it may require reseeding or replacing the damaged areas.
Regular lawn maintenance practices such as proper watering, soil management, and fertilization can help prevent brown patch fungus.

What Is Brown Patch?

Brown patch is a disease that affects the lawn. It causes brown patches in your lawn and is caused by a fungus. The fungus overwinters on dead grass, so it’s most common in warm, humid climates. 

Brown patch can be treated with fungicides or organic products that prevent the spread of fungi such as copper sulfate.

Brown patch is not contagious; you do not need to remove infected areas before treating other areas of your lawn or garden with fungicide because it will not spread through your whole yard (or garden).

How Do You Know If Your Lawn Has Brown Patch?

The first step in diagnosing brown patch is to look for circular, brown patches of grass that are usually between a quarter and a basketball in size.

If you see this symptom on your lawn, it’s possible that you have brown patch disease. Be sure to get it checked out by a professional as quickly as possible!

What Causes Brown Patch?

Brown patch is caused by a fungus called Rhizoctonia solani. This fungus lives on the roots of grass plants, and it causes brown patches to form on your lawn. 

Rhizoctonia solani can be found in many areas where turf grass grows, but some species are more aggressive than others. 

When conditions are right for them to infect your lawn, they spread quickly and cause damage throughout your entire yard as well as any neighboring properties.

How to Get Rid of Brown Patch (4 Easy Steps)

What Are The Symptoms Of Brown Patch?

  • The most obvious symptom of brown patch is a brown patch in the lawn. If you notice an irregularly shaped, light-colored area on your grass (or any other type of turf), it could be that this is brown patch disease.
  • Brown patches also can appear as small circular spots or rings with dark green borders, which are usually not more than 1/2 inch in diameter.
  • When the weather gets above 80 degrees F (26 degrees C), these patches will start to turn reddish-brown and eventually die off completely if left untreated!

How Do You Treat Brown Patch?

Aerate your lawn. This will help remove the thatch layer and allow water to reach the roots of your grass.

Remove dead grass with a rake or shovel, being careful not to disturb healthy grass in the process.

What Is The Cause Of Brown Patch?

To treat brown patch, you must first identify the cause of the problem. Brown patch is caused by a fungus called Rhizoctonia solani, which thrives on dry soil and abundant sunlight. 

This can happen if you don’t water your lawn enough during the summer months or if you have too much shade in an area of your yard that should receive more sun. 

You may also experience brown patch if you overseed your lawn with grasses that have weak roots or are not suitable for your region (such as tall fescue).

If you suspect brown patch, look for circular patches that start out light green and turn brown as they continue to grow throughout spring into summer. 

These patches will often be surrounded by lush green grass and appear lighter than surrounding areas they may even seem greener at first glance but upon closer inspection will appear discolored compared to healthy parts of your lawn.

Is Brown Patch A Disease?

Brown patch is caused by a fungus called Rhizoctonia leguminicola, which thrives in high-moisture environments. Brown patch is most prevalent during the spring and fall when grass tends to be growing more rapidly than normal because of seasonal changes in temperature and humidity levels.

The symptoms of brown patch are quite easy to identify: large dead circular patches appear on your lawn, sometimes with the borders being slightly raised or depressed. 

The dead patches do not have any discoloration or other visible signs of disease; they just appear as dark spots on lighter green grass blades. These areas can sometimes be as big as 10 inches (25 cm) across!

While brown patch does not pose any threat to humans or pets like some plant diseases do, it can lead to weakened turf if left untreated which will make it susceptible to other types of damage such as foot traffic from pets or children playing outside.

How Do You Prevent Brown Patch?

To prevent brown patch, you should:

  • Mow high, at least 3 inches. This helps the grass to develop deep roots and strong stems.
  • Keep the lawn well-watered throughout the summer. Brown patch needs dry conditions to thrive, so keep watering until early September when most of the grass has died back naturally.
  • Avoid walking on the lawn in wet conditions; don’t sit or stand on it either! This allows fungus spores to remain active and easily spread from one area of turfgrass to another nearby area during wet weather (which is exactly what causes this disease).

When Should I Fertilize My Lawn?

When should you fertilize your lawn? The best time to fertilize your lawn depends on the type of grass that is growing in it. 

Lawns with cool-season grasses like Kentucky bluegrass need to be fertilized in spring and fall, while warm-season grasses such as Bermuda need to be fertilized during the summer months. 

In general, it’s recommended that homeowners fertilize their turf every three months from spring through fall and once or twice a year in winter. If you have an established healthy lawn that’s properly watered and mowed, then weekly applications are not necessary unless you’re trying to improve your lawn’s appearance.

When Should I Aerate My Lawn?

If you suspect your lawn may have brown patch, the first thing you should do is aerate your lawn. Aeration helps to remove compacted soil, which improves drainage and allows air, water, and nutrients to reach the roots of your grass. This improves a number of factors that contribute to healthy lawn growth:

  • You can reduce thatch build-up by allowing soil in between grass blades for better root development
  • You’ll be able to achieve a uniform depth of watering with less runoff or ponding due to improved water absorption
  • Your grass will grow faster because it gets more sunlight exposure

When Should I Water My Lawn?

You should water your lawn once a week in the spring and summer, and once every two weeks during the winter. 

The amount of water that your lawn needs depends on how much time you spend outside, as well as how much sun it gets. 

If you’re spending most of your time indoors, then watering more often is recommended since there won’t be as much evaporation from the ground (which means less water will be lost). 

Additionally, if it’s not sunny out for long periods of time without rainfall, then this could mean that your grass isn’t getting enough moisture from rainwater alone!

How Do I Know If My Lawn Has Brown Patch?

If you hear about a disease called brown patch, it’s probably not the one that affects your lawn. Brown patch is a fungus that causes dark-colored spots to appear in your grass, causing it to die and turn brown. 

The cause of brown patch is Phaeosphaeria nodorum (Pn), which lives on the roots of turfgrass plants and gets its name from the black spore sacs (sclerotia) it forms inside affected areas. 

Pn infects most cool season turfgrasses including Kentucky bluegrass, perennial ryegrass and bentgrass.

There are two types of brown patch: primary and secondary. Primary refers to those cases where an area of damaged turf has been present for at least three weeks but no other symptoms such as yellowing or wilting have appeared yet; secondary refers to severe cases where patches are surrounded by dead grass blades that may also be wilted or tinged with purple coloration along their edges (see below).

Is Brown Patch Contagious?

While Brown Patch is not considered a disease, it is caused by a fungus and can be treated with fungicides. It can be identified by patches of brown or dead grass that are surrounded by green or yellow-green grass. 

If you notice these symptoms on your lawn, you should contact a local lawn care service such as Lawn Love and schedule an appointment to have them diagnose the problem and provide treatment options for Brown Patch.

“Weed control is an essential aspect of lawn care and requires regular attention. Our article on can lawn kill weeds landscape advice can help you determine the best approach to control and eliminate weeds from your lawn.”


Brown Patch is an easy-to-recognize disease that can be treated with a few simple steps. Brown Patch symptoms include brown or dead patches on the lawn and dying grass. 

To prevent brown patch, it’s important to keep your lawn healthy by watering during dry spells, adding fertilizer once or twice per year and mowing regularly at two inches tall or less. 

If you do notice signs of brown patch in your yard, call your local garden center for advice on treatment options.
