How To Fix Brown Patches In Lawn

Brown or dead spots on your lawn are not fun to deal with and can be caused by a number of factors. One cause is if the pH balance in soil becomes too high, meaning it’s alkaline rather than acidic like most grass prefers – this will lead browning from occurring as well as other problems such as negative effects when walking through certain areas because they’re contaminated with urine . To fix these issues you could add lime which helps balance out those ranges again but sometimes more drastic measures may need to be taken: replacing both topsoil/compost AND plant material entirely.

A lawn thats starting to turn brown means a deep watering is needed, but not always. It can also mean the opposite – if some types of grass are experiencing more rainfall than others and they start drying out before their counterparts in other parts of your property or yard do so effectively enough because soil quality varies from place-to-place depending on what kind it is how much naturally occurring sunlight reaches each individual blade whether fertilizers have been used at all times over many years without interruption by waypoints along this journey towards sustainability–it takes time!

You can apply fungicide and fertilizer simultaneously if you are applying a fungicide that needs to be watered into your lawn.

All too often turf managers spray a fungicide when disease develops and think the product does not work when they do not observe recovery within a few days. Rapid recovery could occur when fungicides are applied immediately after disease develops and the disease is not severe. However, how long would it take for turf to recover once severe disease develops? Recovery is only partially dictated by the fungicide application. Most of the recovery process is governed by environment, fertility, and cultivation.

What To Do Before Installing Your Lawn

The fight against fungus on the lawn in fact starts as early as the stage of establishing a new lawn. This is done by thoroughly clearing the soil under the lawn of any plant residues that may rot and decay in the future. These might be promoting the development of fungus.

If the soil is sandy, it may be useful to fertilize it and improve its physical properties. This is done by utilizing appropriate organic and mineral fertilizers before the lawn is laid. It may also be beneficial to install an irrigation system. Doing so will eliminate the exposure of the lawn to long periods of drought.

How to get rid of the fungi on an existing lawn?

First of all, regular lawn care is necessary. After each mowing, the remaining cuttings of grass must be removed. As a result of removal, they wont form a layer of felt when drying. Existing old felt will be removed by raking, scarifying and aeration.

Scarifying is a flat, vertical notch of turf, while aeration is a deeper puncture with spikes. These treatments loosen up the soil and aerate it. Scarifying should be done at the beginning of the growing season. it can be repeated 2-3 times per season.

If you decide to spray the fungus on the lawn, scarifying it beforehand will make it easier for the best fungicide to reach the grass roots deeper. A good lawn owner always ads nitrogen-rich fertilizers.

Mow Regularly At The Right Height

Mowing too short weakens the grass plant, making it more susceptible to infection. Most grass types should be mowed using a high mowing setting. Bermudagrass grass in the south should be mowed using a lower mower setting and zoysiagrass should be mowed using a middle setting. Mow often enough so that no more than the height of the grass blade is removed at one time.

How Often To Apply Fungicide For Prevention

We’ve had trouble with our tall fescue/bluegrass and fungus/disease in past years, and this year will be applying fungicide as a preventative measure. Wondering how often it needs to be re-applied?

Should we wait till nights remain in the 70s to begin applications? I have a bag of Lebanon Eagle ready to go… In past years, disease/fungus seemed to start in mid to late June and worsen thru July and August.

BTW, please don’t tell me that I should be growing warm-season grass…I know TTF/KBG is out of it’s preferred climate here, but I want to make the cool-season grass work if at all possible and am up for the challenge. 🙂

Any other tips from people growing fescue/bluegrass in warm zone appreciated!

    I usually put down fungicides may – august every 30 days here in the Charlotte area…make sure to get 2 good ones that last for 30 day and alternate.

    How To Treat Your Yard For Lawn Fungus

    Once you have determined what type of fungus or disease is present, its time to treat. Its best to treat a diseased lawn as soon as you spot the problem, as some diseases can spread and kill the whole lawn.

    The type of disease or fungus you have will determine the best treatment option. In some cases, the issue is weather or seasonally dependent and will clear up on its own once the weather changes. Other problems need immediate mitigation, such as fairy ring, powdery mildew, or smut, as they can kill the plants or cause permanent damage to the lawn.

    To treat your issues, first identify whether it can be eradicated via changing your practices. Powdery mildew, for example, may be able to be taken care of by rinsing the plants and getting rid of leaves or any other nearby debris that is causing it to spread. Avoiding overwatering, letting the grass grow a bit longer between mowing and not over fertilizing can also help clear up the problem.

    Some homeowners prefer to try to treat lawn diseases organically, rather than using fungicide. If your areas of fungus are small, using treatments like neem oil, cornmeal or baking soda solutions can be effective. Before you opt for an organic approach, though, do your research and be aware of the potential drawbacks. In some cases, using home remedies can only make the problem worse, or introduce new, unexpected issues.
