How To Plant Grass Seed In Bare Spots

How to treat for brown patch in the lawn

Perhaps you are already familiar with how to seed your lawn. However, reseeding dead spots in a lawn calls for added attention to detail. We have outlined the steps on how to plant grass seed in bare spots for your next lawn repair.

  • Remove Debris

Before you start seeding the brown patch, remove any leaves or debris from the area to avoid damage. This removes any obstacles in distributing the seeds evenly among the dead grass. If the brown patch in your lawn was caused by urine or chemical spills, thoroughly rinse the area several times before reseeding to dilute any harmful chemicals.

  • Break up the Soil

Refresh the soil of the brown patch by taking a rake or a garden cultivator to till the ground in your summer yard. This will help ensure that the soil is loose and ready to take in the new seed.

  • Add Compost

Using compost is a great way to add nutrients back into the soil. Add a 2 to 3-inch layer of compost or loamy soil and use the rake again to mix it with the existing soil.

  • Even out the Surface

Use the top of the rake to make a flat and even surface to start sprinkling the grass seed.

Evenly distribute a thin layer of grass seed over your brown patch.

  • Protect the Seeds

If you choose to sprinkle the seed on top without pre-mixing it in the soil, place a thin layer of straw over the area to prevent birds from eating the seeds. Once the grass starts to bud, remove the straw.

  • Keep the Area Lightly Watered
  • Lightly Fertilize
  • Wait to Mow
  • Monitor the Area

What Is The Mowing And Watering Frequency To Prevent Brown Patch On Lawn

Brown patch fungus is a common problem on lawns. It can be caused by a number of factors, but the main one is overwatering. Brown patch fungus grows best in moist, warm soil. Moisture and warmth are provided by frequent mowing and watering. To prevent brown patch fungus from growing, follow these guidelines:

  • Mow your lawn only once per week. Mowing is good for soil monitoring which is fine method to deal ith brown patches.
  • Only water your lawn when it is really dry. Spreading water around when it is wet will only Cause runoff that can carry pollutants and fertilizer into waterways and contaminate them with brown patch fungus.

What Is Brown Patch

Brown patch is a soil-living fungus which becomes active in humid months where temperatures reach the mid 80s during the day, and mid to upper 70s overnight.

Like the name would lead you to believe, brown patch causes a brownish discoloration of your turfgrass. More specifically, it starts out with lesions on the grass blades .

As brown patch develops, these lesions spread to cover the entire grass blade, causing thinning and matting of the turf. On shorter lawns, these patches may appear to have a “smoke ring” of dark gray around the outer edge.

Grubs cause brown patches in your yard where they munch on grass roots. This kills your grass in the process. To identify a grub issue, dig up a patch of grass and looking at the roots.

How To Spot The Fungus

Getting Brown Spots in your Lawn? Causes + How to Get Rid of Brown ...

The funny thing about brown patch is that it doesnt start out brown at all. In fact, the first signs of trouble are when a circular or oblong pattern of light-yellow discoloration appears in your grass. Eventually, the affected area will turn from orange to tan. It will continue to spread outward, sometimes leaving small green patches at the center. The discoloration is caused when the fungus infects each leaf, causing them to rot.

Brown patch fungus can affect all cool-season grasses, but it is especially harmful to ryegrass and tall fescue. Brown patch also affects a variety of warm-season grasses, including St. Augustine grass, Bermuda, and zoysiagrass.

One of the most frustrating aspects of brown patch is that once you spot it, the damage is already done and the fungus is thriving. The trick to successfully eradicating brown patch is understanding the fungus lives beyond where the eye can see, in your soil. When the conditions are right, the fungus strikes, making preventive measures all the more important.

When Should You Treat Brown Patch

So, based on how fungus tends to disappear on its own, you might be wondering when you should go ahead and treat it.

The truth is, if you see that its not going away on its own, then its best to move in for the kill before it starts to spread.

Brown patch can cause damage to grass types such as perennial ryegrass and tall fescue.

It makes the grass grow in an unhealthy way because of how the fungus is consuming it.

In addition to the damage it can cause, the brown fungus can be a sore thumb when you look at your otherwise beautiful garden, which is why you dont have to wait for it to go away on its own.

However, since it will tend to disappear in the same way that it came, you dont have to resort to products such as chemical fungicides to send it packing.

Its actually better to avoid these products altogether, as they can be damaging to your health as well as the environment.

As the U.S. Fish and Wildlife Service reports, these chemicals can actually stay active in the environment for long periods of time during which they harm the water and soil.

What Are Brown Patches In Lawns

How to Control and Treat Brown Patch l Expert Lawn Care Tips

Brown patch is actually caused by a fungus called Rhizoctonia. This tough fungus will lay dormant over the Summer, then spring into action once temperatures start to reach around 70°F, and is at its most potent when temperatures range from 8085°F. It often pops up right after heavy rain events and cloudy days.

In the very early stages of fungal development, the grass will look wilted and wet, and the grass edges may look wavy. This stage doesnt last long, though, and soon it will turn into a brown patch that gets matted and sunken into the ground. Brown patch spreads outward quite fast from a central point, so as soon as you start to see brown circular patches popping up in your grass, its time to get to work. You may often notice a rusty orange ring around the patches, or spots where two patches meet and form an irregular shape.

What Fungus Causes These Brown Patches In Grass

Before we can start treating the brown patches caused by a fungus, we need to know what type of fungus is actually the culprit.

There are millions of fungi species, after all!

But, a fungus thats known as Rhizoctonia is whats causing those brown patches to occur on your lawn.

This type of fungus tends to strike when the temperatures are really hot and humid.

This fungus is quite sneaky because it manages to survive in the thatch of grass during the colder temperatures in winter, and then it penetrates the grasss leaf tissues through cuts that are caused to the grass, such as when it gets mowed.

Your grass might not immediately show signs of fungal infection until the temperature gets hot and then youll be able to see the symptoms start to appear.

Rhizoctonia is said to target lawns, but it can also affect plants.

If you see any black or brown spots at the base of the plant stems near the soil line, then it has been infected with this fungus.

If left untreated, these marks can grow and the fungus will end up obstructing the plants uptake of nutrients and water from the soil, leaving it to die.

You can also spot Rhizoctonia on fruit plants, and if their leaves or fruit are close to the soil where they often get splashed with water, such as during watering sessions, this can cause the fungus to form and spread, Greenhouse Grower explains.

The problem with these brown fungal patches in your grass is that they spread really quickly.

Here are some ways to do so.

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.

Lawn Fungus Cure – Brown Patch and Dollar Spot

In addition to those conditions that cause brown patch lawn disease to appear, there are also some areas that tend to be more sensitive to its spread. Poor air flow will exacerbate high temperatures and humidity. For instance, if your property is surrounded by woods or if you have a fenced-in yard — any areas where there is a break in air circulation — youll likely find more brown patch in these spots. Periods of rainy weather during humid days can also promote the appearance of brown patch. Things that accelerate this include poor soil drainage, compact soils, excessive thatch, and poorly maintained lawns.

Can My Lawn Grow Back After Brown Patch Pythium Blight Or Dollar Spot

The only way the grass can recover from dollar spot and brown patch damage is for the grass to grow enough that the damaged blades are pushed up and mowed off, revealing new and undamaged blades below. Tall fescue and Kentucky bluegrass grass types grow more slowly as temperatures rise so it would take weeks or months for the grass to recover. And, it may require fall seeding to get the lawn back into shape. Thats why preventing damage before disease development is so important.

The best products for preventing and controlling lawn fungus are very expensive. Understanding turf diseases, their control, and when and how to apply them is very important. To get help with your lawn and protect it from fungus, request an estimate for disease control from a professional lawn care service.
