Brown patches on a lawn can be caused by a variety of factors, including lack of water, overwatering, poor soil quality, disease, and pests.
To prevent brown patches, water your lawn deeply but infrequently, avoid overfertilizing, and keep an eye out for signs of disease or pests.
If you have brown patches, it’s important to identify the underlying cause in order to properly treat the issue.
Treatment for brown patches will depend on the cause, but may involve overseeding, aerating, applying fungicides, and adjusting your watering and fertilization schedule.
Restoring your lawn after brown patches have developed may involve a combination of treatments and is best done with the help of a lawn care professional.

Let’s explore these solutions and keep your lawn looking lush and green!

Fertilize Your Lawn

You may also want to fertilize your lawn to help it recover. This is a good idea if you live in an area where fertilizer is recommended, as the climate can make it difficult for grass to grow without some added nutrients. 

Fertilizer will help fill in the brown patches and make your lawn look healthy again.

There are two ways you can fertilize: liquid or granular fertilizer. You’ll need to follow instructions on the packaging of either option carefully

But they’re both relatively easy processes that involve spreading the substance over your yard and letting it absorb into the soil below before watering it in with water from a hose or sprinkler system so that everything has time to settle properly before continuing with other activities such as playing on or walking through your yard.

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

Water At The Right Time

In addition to not over-watering, you’ll want to avoid watering your lawn at night or in the early morning. Watering at these times can cause fungus in your lawn, which will lead to brown patches. 

Instead, make sure you water when it’s dry outside for about two hours after sunrise and about two hours before sunset. Once again, apply 1 inch of water when watering—but do so infrequently. 

You’ll actually want to let your grass go between watering sessions without any moisture at all!

Replace Or Repair Your Sprinkler System

If your sprinkler system is damaged, you might need to replace or repair it. 

The system can be damaged by freezing, and then the sprinkler heads may break off and not water properly. 

Your timer could also be set to run too long at one time, resulting in brown spots on your lawn. Or the controller might be broken and unable to turn off the water when it needs to.

Change Your Mowing Pattern

Mow more often in spring and fall. Depending on your grass type and climate, you may need to mow more frequently during these seasons (perhaps once a week) than you do during summer. This will help keep the blades of your lawn healthy.

Mow less often in summer. In warm weather, grass needs less water and fertilizer than it does in cooler temperatures; therefore, it’s best to cut back on your mowing schedule so that your lawn doesn’t get over-mowed while it’s still growing fast.

Aerate Your Lawn

Aerating your lawn is perhaps the easiest of all steps to take. In fact, it’s really as simple as renting an aerator from your local hardware store and running it over your lawn. 

The process itself takes only a few minutes to complete, though you may need to deduce where exactly you want to aerate based on how deep the soil needs to be turned over.

Once finished with this step, simply remove any chunks of dirt left behind by your aerator and replace them in their original locations after raking up any loose grass clippings or detritus on top of them (you don’t want those things getting stuck in your mower). 

You should also leave this area alone for several days until you’re ready for another pass at it; doing so will allow time for rainwater or irrigation systems (if present) to work through any loose areas or clumps that remain exposed after initial aeration efforts have been made. 

Finally: make sure not to overdo it! If only half an inch has been removed from beneath their surface level due diligence dictates that no further action should be taken until springtime when new growth begins again next year

Rake Up And Dispose Of Leaves

You should regularly rake up leaves and dispose of them in the trash or compost bin. Most importantly, do not leave them on your lawn because they can smother grass by preventing sunlight from reaching the ground (this can be especially detrimental for newly seeded areas). 

The decaying matter can also lead to fungal diseases and clog sprinkler heads. Additionally, leaves attract pests like ants and mice that could make mowing difficult. 

They may also change soil chemistry by adding acidity to it through decomposition.

Avoid Walking On The Lawn When It’s Wet

One of the best ways to avoid brown spots in your lawn is to avoid walking on it when it’s wet. If you must walk on the lawn, use a broom to remove excess water before stepping onto the grass. 

If you have to walk on the lawn and don’t want brown patches, try wearing shoes that are easy to clean and don’t hold water (like canvas sneakers).

Use A Fungicide, If Needed

There are several types of fungicides, and you’ll need to use the right one for your particular situation. 

You should also consider how much time you want to spend on this project. If there are only a few patches that need attention, it’s likely not worth spending hours mixing chemicals in spray bottles.

If you don’t know which type of fungicide is right for your lawn fungus problem and how much time you’d like to spend on this project (if any), consult with a local landscaper or pest control company.

Consider Dethatching And Overseeding

If you notice that your lawn is thin, you may want to consider dethatching and overseeding. Dethatching removes the thatch layer from your lawn and overseeding adds new grass seed. 

Dethatching and overseeding are best done in the fall when temperatures are cooler and there’s less chance of damage from mowing or other maintenance activities. 

To get started, use a lawn rake to dethatch any areas where grass has grown tall enough so that visible roots are showing through at the surface of the soil (these can be seen as dark spots on an otherwise green patch). 

You’ll want to remove as much of this dead matter as possible using a sharp blade on your rake before moving onto step 2: overseeding. In order for new seeds to germinate properly, they need good soil contact — so using a spreader will help ensure even distribution throughout your yard!

Be Aware Of Heat Stress

Lawns are most susceptible to heat stress during summer months when temperatures regularly exceed 90 degrees F (32 C). 

Heat stress can cause brown patches on your lawn, especially if you’re not keeping it well watered. 

In addition to watering properly, avoid applying fertilizer when the ground is too hot. If you do choose to fertilize, keep the soil moist but not soggy; overwatering can lead to root diseases or fungal infections that cause further damage.

Look For Signs Of Disease Or Pests

If you suspect that your brown patch is actually the result of a disease or pest infestation, you should look for signs of their presence. Most commonly, these include:

  • Small holes in the lawn
  • A soft, spongy texture
  • Yellowing and wilting blades of grass

Avoid Over-Fertilizing Or Excessive Water

This is a common problem, and the best way to deal with it is preventative.

If you have brown patches on your lawn, avoid over-fertilizing or excessive water. You should also use slow-release or granular fertilizer (a mix of nitrogen, phosphorus and potassium) in the fall while leaves are still on the trees. 

This helps prevent excess nitrogen from getting into the soil when new grass grows during springtime.
