How Do I Know I Have Lawn Disease?

A common question we get is how to know whether you have lawn disease!

Many common lawn issues can be treated with water, seeds, and basic maintenance. However, if you see brown patches around your lawn, even though you’ve been watering, mowing, and doing all the normal maintenance, you may have lawn disease. 

Other signs may include slimy patches of grass, a thin film covering your grass, powdery mildew on individual blades of grass, or irregular patches of non-green grass. Basically, if there is anything funky-looking in your lawn that cannot be attributed to your pets, then there is a strong likelihood that you have some sort of lawn disease. 

It is important to pay close attention when you first start to notice any lawn disease symptoms or signs, as you want to catch any issues early and proactively address the issue. Lawn diseases can spread very quickly to more of the lawn! If you see the beginning stages of browning or random patches of dead grass, you should give us a call immediately. We can help to treat the lawn disease before it spreads to the rest of your lawn and get you lawn disease under control.

Full Communication

A common misconception about plant health specialists is that we come into your lawn, treat the problem, then leave. 

That may be the case with the big franchises, but that is not the case with us! We make sure to leave instructions on how to care for the lawn now that you have gotten the lawn diseases under control. We will leave clear instructions on how and how often to water the lawn, how you should mow the lawn, and anything else we think you need to know. We ensure high-quality and consistent communication because our vast experience has demonstrated that that is what our customers need most from us.

Basically, we want to avoid you saying, “Nobody said anything to me!” We want to make sure that after we do the lawn treatment, you are armed with all of the information you need to make sure that your lawn stays healthy for a long time. Each time we come out to your lawn, we will pay detailed attention and make note of anything in your lawn that needs special attention. Lawn disease maintenance is a team project.

Trusted St. Louis Lawn Disease Control Services

There are a lot of lawn disease experts out there. However, nobody knows St. Louis climate and lawns like we do. Our 40 years of experience in the area have shown us what patterns and behaviors lawns in St. Louis demonstrate. 

The reality is that not all grass seeds are the same. Not all turf is the same. Not all lawn disease treatments are the same. Not all fescues are the same. We know what works well for St. Louis lawns, and we want to continue to share that acquired knowledge with our customers.

We know that bluegrasses and ryes have the most problems, as they don’t like the St. Louis climate. Low-quality fescues, Kentucky 31 tall fescues, and falcon tall fescues also do not perform well in St. Louis. They are not very resistant to brown patch fungus, for example. High-quality fescues fare the best in the St. Louis climate and ecosystem. We, at Pure Lawn, tend to recommend Winning colors fescue.

You can also consider turf. There are four different varieties of turf, each with their own pros and cons. Each fare differently in the St. Louis climate, as well. That is why you need an expert in this specific geography and ecosystem, not just someone who uses a blanket method across various climates in the United States.

Brown Patch Disease

We mentioned brown patch disease earlier, but we didn’t really talk about it! Brown patch disease is often the hardest lawn diseases to notice, as it looks like patches of dead grass. 

The main way that you can determine whether you have brown patch disease or just dying grass is to water and maintain your lawn regularly. If you find that regular watering and seeding isn’t making the patches go away, then there is a high chance you have brown patch disease. If that is the case, then you should call us immediately!

Brown patch disease is a fungal disease caused by the fungus Rhizoctonia that causes grass thinning and wilting. It is very common, and thrives in hot, humid environments. 

Brown patch disease in a non-sporulating fungi, meaning that it does not spread by spores. The fungus spreads by moving on individual blades of grass, resulting in large patches of fungus-infested grass. Once treated, the recovery from brown patch disease may take a while, as the fungal-infested grass will need to regrow.

Dollar Spot Disease

If you are seeing small, circular spots in your lawn, then you probably have dollar spot disease. Grass that is infected by dollar spots look like they have been soaked in water, and they tend to have yellowish-red spots on the blades of grass. “Dollar-sized” spots tend to show up around your lawn, and you may see cobwebs growing between blades of grass. Dollar spot thrives in humid environments, so you may get a growth of dollar spot if you overwater your grass, and the water does not sink into the root. Therefore, the best way to prevent dollar spot is to not overwater your grass and to apply adequate nitrogen fertilization. 

Dollar spot typically shows up in circles of 2-3”, but if left untreated, can spread to various areas in your lawn. Dollar spot can be incredibly damaging to other turfgrass areas and other lawns. Dollar spot tends to be active from May to October, so that is the time to keep an eye out for it. This is also when people tend to be most active on a lawn, and dollar spot is spread by shows, carts, wind, and water. Pretty much anything that can carry the fungal spores will, allowing dollar spot to easily spread in high-traffic areas. It is important to get your lawn disease under control as soon as possible.

Red Thread Disease

Red thread disease is not very dangerous in and of itself, but it facilitates an environment where other diseases can infect and spread in your lawn. Red thread disease is caused by the fungus Laetisaria fuciformis, and is common in the north. Red thread disease likes perennial ryegrass and Kentucky bluegrass lawns. 

Red thread disease is probably the easiest to notice because of the conspicuous coloring. Consistent with the name, red thread disease shows up as patches of red or pink in your grass. Over time, if left untreated, red thread disease will cause the grass to take on a bleached straw color.

Red thread disease also prefers hot, humid environments. It tends to co-occur with pink patch disease. To prevent red thread disease, do not overwater your plants and ensure adequate nitrogen fertilization. A lot of people will not treat red thread disease because it is not as dangerous as some other lawn disease, but we don’t want red thread disease to spread throughout the lawn, so we will treat it properly.

Leaf Spots

Lastly, leaf spots is another common type of lawn disease in St. Louis. Leaf spots are easy to notice because they show up as dark spots on leaves. While most leaf spots happen because of fungi, they can also be caused by bacteria as well. Leaf spots can be deadly to your plants because they disrupt the photosynthesis cycle. Photosynthesis is how plants create energy, so although leaf spots are not immediately hazardous to plants, over the span of a few years, you may begin to see reduced growth and incredible damage to your plants. 

To prevent the spread of leaf spots, immediately dispose of the leaves in order to prevent the bacteria or fungus from spreading across the leaves in the tree. You will see most of the impacted leaves toward the lower and inner branches of a tree. This area is where the humidity is the highest, so the disease is able to develop and spread quicker. The colors of the spots can be highly variable, depending on the exact fungus or bacteria causing the disease.

Don’t Let Lawn Diseases Spread

It is important to treat lawn diseases early because they can spread to your entire lawn, which can kill your entire lawn. At that point, you will need to re-seed and re-grow your entire lawn, which is costly and time-consuming. By treating your lawn disease early, you can get ahead of it, keeping costs low and making sure that your lawn always looks good. 

Furthermore, if you have small children or pets that play in the yard, you do not want fungal spores to be inhaled. While there may not be significant health effects, you may begin to see cold symptoms that are painful to treat. For your family’s safety, it is also best to treat lawn disease early.

The best way to treat lawn diseases early is to give us a call! At Pure Lawn, we offer free soft soil treatments with each lawn care package and work hard to eradicate lawn diseases wherever we find them.
