Can Grass Recover From Fungus
Grasses are remarkably resilient plants and, in most cases, will fully recover from a fungal infection. Its important to remember though, that there is no way to completely eliminate fungus from a lawn once its taken hold. Though they can be rendered dormant, fungal spores will persist. This, however, is not uncommon. Most lawns host multiple varieties of inactive fungus and are perfectly fine. The key is depriving it of the conditions that it needs to grow, which can be accomplished in many ways.
Fertilize Your Lawn Appropriately
Using too much fertilizer can make your grass prone to fungi. Too little fertilizer can do the same. If you are concerned about fungus on your lawn, it may be a good idea to try an organic, slow-release fertilizer.
Excess nitrogen in synthetic fertilizer quickly makes a lawn green but can also disturb the natural ecosystem of the lawn. If you want your grass to be less prone to disease, organic fertilizer may be the right solution.

How To Identify Lawn Fungus Diseases
Its not always easy to tell whether or not your lawn has a fungal disease or if theres some other issue. However, most fungal diseases have tell-tale signs that will tell you whats going on.
Some signs that your grass may be dealing with a fungal disease are:
- Patches of grass that are white, yellow, brown, or slightly gray in color that are growing in diameter. Or, patches of frayed, mangled, or dried out grass blades.
- Possible diseases: Brown patch disease, summer patch disease, rust lawn disease.
There are other fungal diseases that we havent listed that may be a little less common. Consult a lawn care professional for a diagnosis!
Causes Of Brown Patch Disease
Your lawn is more likely to suffer from fungal diseases under certain harsh weather conditions including high humidity and extreme precipitation. As such, homeowners in Coastal regions like Florida and California are more likely to experience brown patch disease on their lawns.
In general, the common causes of brown patch disease in St. Augustine lawns are:
- Prolonged periods of wetness especially in shaded areas .
- Overfertilizing and overwatering your lawn.
- Too much shade.
Mild daytime temperatures of between 70-90 degrees Fahrenheit and cool nights also provide perfect conditions for the spread of brown patch disease on St. Augustine lawns.
Poor lawn maintenance also provides the perfect conditions for brown patch fungi to invade your lawn. Lawns that are scarcely watered during spring-summer and lawns that experience high-foot traffic leading to soil compaction are, thus, more likely to be infected with brown patch fungal disease.

Simple Treatment And Prevention Strategy
Heres the deal for cool season lawns you should mostly be concerned about fungus in late spring/early summer. Thats when your lawn is most vulnerable and fungus can overtake your lawn and kill infected areas.
For prevention, apply Scotts DiseaseEx in late spring/early summer before the real heat kicks in. Apply at 2-3 lbs per 1000 s/f. to your entire lawn.
If youre already starting to see disease pop up then apply with the curative rate of 3-4lbs per 1000 s/f rate, and apply whenever you notice that your lawn is infected, even if its early spring. Diseases such as Red Thread and Leaf Spot can hit cool season lawns before the summer hits so always be on the lookout since early intervention is so key in combatting disease.
Also, for a curative treatment have the Propiconazole in a tank sprayer on hand just in case you see signs of disease. Some diseases are widespread, while others may appear as specific patches. If you notice specific problem areas, or patches, then spot treat those areas with Propiconazole mixed at the curative rate of 2 oz per 1 gallon of water. If you see a widespread fungus such as leaf spot throughout your lawn, then spray your entire lawn with the Propiconazole. Just note that you should wait a couple days after applying Scotts DiseaseEx before spraying Propiconazole. If disease problems continue I would do a follow up treatment with the Propiconazole about 20 days later.

Signs And Causes Of Bermuda Grass Fungus
In general, bermuda grass should only be grown in locations that get full sunlight, or direct sun for at least four hours or more daily. Otherwise, it will grow weak and become susceptible to bermuda grass diseases, including fungi and others.
Sun gives bermuda grass the energy it needs to grow into a full and thick turf, which is the goal of every yard owner. In less than optimal conditions, bermuda grass wont look as great or last as long as one that gets all-day sun.
Too much thatch or grass clippings left from a recent mowing and too much watering can also lead to the development of fungal diseases in bermuda grass. Aside from that, you will have to make sure your lawn is getting enough nutrients so it wont likely get sick.
The most common problems that affect bermuda grass include anthracnose, dollar spot disease, and lawn rust.
Anthracnose often afflicts Bermuda grass in warm weather, with brown spots and irregular shapes on young Bermuda leaves. Upon closer inspection, youll likely find orange or brown blisters, as well as yellow spots in the blades of grass. Shoots can also be pulled from the ground easily.
Dollar spot disease can affect bermuda grass starting spring through fall, with cool nights and humid weather allowing the growth of fungus. Signs include circular brown spots, cobweb-like growth at the surface, and reddish-brown margins.

What Else Might Be Wrong With My Grass
There are several other reasons your grass might be dying or yellow. A pest infestation, underwatering, iron chlorosis and too much shade also cause your yard to die.
When it comes to lawn pests, chinch bugs are the most common culprit to eat away at your grass. These insects typically start near concrete areas such as driveways, sidewalks or curbs. To test for chinch bugs, cut the hole out of the bottom of a metal can . Push the can into the yard about one inch deep near the dead patch. Fill the can with water. If you have chinch bugs, these pesky pests will float to the top of the water.
Grubs can also damage your lawn by feeding on the roots. These creatures can cause damage to your grassespecially after you resodwhich can result in your being able to lift turf like a carpet, especially if you have St. Augustine. To determine if you have a grub problem, cut a one-foot square piece of sod in your yard where you believe you have a problem. Lift the section up and visibly inspect it to see if you see the grubs in the soil.
If your grass needs more water, the blades will typically curl in. When you walk across a lawn that is water-deficient, you will be typically be able to see your footprints. To avoid lawn damage from insufficient water, try to water deeply and less frequently instead of watering every day.
If your grass has yellow stripes or is completely yellow, you may have iron chlorosis. This condition occurs when you have too much phosphorus in your soil.

Use A Totally Clean Aerator
When aerating, do it with a clean machine. The aerator teeth need to be 100 percent clean before and after use as fungus spores transfer easily from lawn to lawn with aerators and mowers. We recommend spraying the coring teeth with one part rubbing alcohol to 10 parts water to sterilize your aerator after cleaning.
Improve Soil Air Circulation
Improving the air circulation around your yard and soil will reduce humidity and reduce the time it takes for the turf to dry out, which further negates the conditions needed by brown patch fungus to spread. Air circulation can be improved by aerating the lawn and dethatching to reduce the thatch layer at the soils surface, as well as pruning back any large trees, shrubs, or other foliage that may be blocking the flow of air around your yard.

How To Prevent Lawn Fungus In The First Place
Unfortunately, a lot of times turf disease is beginning to fester before homeowners realize it and they make the problem worse. Watering habits and mowing habits are two practices that can ultimately have a pretty big impact on disease.
For one, it is recommended that you water early in the morning which gives the sun time to dry your lawn out. When you water in the evening hours, that water sits on the lawn and creates a habitat that can breed fungal growth.
Mowing habits also make a difference. You should keep your mower blades sharp and clean in order to prevent spreading disease. If you are utilizing a professional lawn mowing service and they are not cleaning their mower deck after each lawn , they could be spreading disease from one lawn to another.
In addition to certain cultural practices, you can also invest in preventative care. At Master Lawn, our Gold Program includes preventive turf disease treatments already built-in, allowing you to put disease worries out of your mind.
Given the severity of some of these diseases, a proactive approach is ideal so that you never even give these menaces the chance to wreak havoc.
Avoid Nitrogen Heavy Fertilizers
Lastly, avoid nitrogen heavy fertilizers. Lawn fungi love nitrogen so adding nitrogen to a lawn at risk for a fungal infection isnt a great idea. You can avoid a lawn fungus explosion by using a slow-release nitrogen fertilizer during the spring and summer. This way your lawn gets the benefits of the fertilizer over a longer period of time and you avoid feeding the fungus.
