Lawn Rust Disease: Ways to Identify, Cure, and Prevent

If you start talking about the most common and irritating lawn diseases, I am sure that you have to keep the lawn rust disease at the top of the list. In European and American provinces, this disease has become prevalent due to the weather that causes extra moisture on the lawn soil.

Basically, the rust on the grass leaves results from fungus infection and can spread rapidly if you don’t take care of it from the beginning. However, identifying the rust disease is another challenging task as well. It looks similar to the dry patches on the lawn, which many people consider sunburn.

If you are concerned about your lawn, I think you should spend a few minutes learning about this common lawn disease. If you agree with me, I am sure this content will come as a great help. From its nuts to the bolts, I will try to cover everything about the disease here in one place. So, skip it at your own risk.

What Is Lawn Rust Disease?


Lawn Rust DiseaseRust is a common problem that occurs mainly on turf grasses. Lawn owners find this lawn disease most often, especially when the growth of the grass is slowed. A fungus infection causes it, and it affects your lawn mostly in late summer or early Fall.

When the environment is hot and lacks enough moisture, the rust fungus can attack your lawn grass, but it is not the main reason. Also, many people find them at the time of dusty weather and when the grass lacks nitrogen. So, insufficient appropriate fertilizer for the lawn is a significant reason for this disease.

Though lawn rust spreads rapidly through its spores, generally, it is not always required to use fungicides on it. Also, extra moisture can be responsible for this disease, not just the dry season. Besides, not just your lawn grass; if you have a garden, you will find the same condition on the leaves of different plants.

How to Identify Lawn Rust Disease?


Identify Lawn Rust DiseaseYou must know that most lawn diseases share similarities with each other. So, many times it is difficult to identify specific lawn diseases. However, identifying lawn rust disease is easy though this fungal infection pretty much looks like the brown patches. But the best way to identify this disease is to check the grass leaves.

You can simply pull off a few blades from the turf if you see symptoms of this unpleasant disease on grass. In the beginning, it makes the yellowish brown affected area in the leaves. Gradually, it changes color and finally turns into an orange, red, or deep brown color. The entire leaf will change color and then die.

Generally, the spores of this fungus live on the tip of the grass. Consequently, they started to spread and finally affected the entire grass area. A finger can rub off the spores of this rust disease. But that is not the best way to kill it.

Commonly, this disease affects many different types of lawn grass. From ornamental plants to evergreens, all the green areas might be covered by rust problems. Eventually, it can cover the entire lawn and leave a dead lawn if you don’t take care of it from the beginning.

Causes of Lawn Rust Disease


Causes of Lawn Rust DiseaseMany people are concerned about rust disease as it is quite a deadly lawn disease. However, you should learn the cause of this disease so that you can find an easy cure for it. This fungal disease often appears because of heavy rainfall, cool nights, or fluent haze.

If the grasses don’t get enough sun exposure and can’t dry out in 6 to 8 hours, they can be susceptible to rust fungus. Damp or extra moisture allows the fungal infections to grow. Low lights, shades, or shorter days can be a trigger to this problem.

Even moist weather is another reason which encourages this problem. If the temperature is 70 degrees F with a high dew point, rust on the grass will come off easily. Excessive thatch is also a hindrance to getting rust-free grass. And also, it is rare, but the too much drier season can be a cause of this disease as well.

How to Prevent Grass Rust Diseases?


Many seasonal and fungal diseases can cause severe damage to your lawn. And rust disease typically attacks the weak grass after draught. You can prevent grass rust disease just by following some easy tasks. Check out and get acquainted with them in the following section.

1. Aerate Your Lawn Timely


Aerate It TimelyYour lawn needs proper aeration at certain times of each year. This process saves the lawn from unwanted problems like rust disease. Keep in mind that you don’t need to aerate in the winter; rather, you should do it in spring and autumn. Yes, just before the winter hits and after the cold has passed.

These holes in the soil give proper ventilation, nutrient management, moisture control, and much more. You can use special aeration tools or garden forks to make these holes which would help to hold water and air and penetrate the soil.

Unlike other fungal diseases, this rust disease takes place on the live grass, which is prevalent in and after draught season. Aeration can help remove the possibility of this grass disease and also improve the drainage system significantly.

Another way to prevent grass rust disease is to provide adequate sunlight and airflow. This may sound like easy work but not always, as this greatly depends on your place and the location of the lawn. Your nearby buildings, big trees, and other immovable structures can sometimes cast shade and even block positive airflow.

You can remove any structure that is providing unwanted shade on the lawn, such as hanging beaches of a tree. These type of low branches blocks light and air. The branches that are above 3 feet from the floor level are good. Brunches lower than that should be cut. Another proceed is pruning hedges and large thick bushes. By doing so, more air and light will pass through.

Additionally, you can replace the fencing system for optimal light and air passage to the lawn. It could be tiring but a must-do if removing share sources and eradicating bushes do not work. Replacement of the solid fence panel would lessen the moisture on the surface and promote the health condition of the weak lawn.

3. Mow the Lawn


Mow the LawnOne of the best ways to prevent grass rust disease is to mow the lawn on a regular basis. Not just random mowing; it has to be done correctly. You have to keep the grass size at a minimum level so that it will grow sideways rather than upwards. This will eventually create new roots, shoots, and more grass leaves in the same area. The denser the grass, the better.

The most important way to keep the lawn grass healthy is to cut them regularly. Keep in mind that grass leaves and roots trap the sunlight and utilize the energy to produce food and store them for long periods. So, it is better to have dense and keep the grass heigh short. This makes lawns more healthy and resistant to potential diseases like grass rust disease.

4. Water in the Hot Weather


You must regularly water the lawn in warm weather; it is a very simple task, yet most people do it wrong. Most lawn owners water their lawn in the evening using a garden hose which is vastly problematic on its own. First of all, this leaves the water on the grass, not the soil. But, grass or leaves does not utilize water; it requires the water to get into the soil and roots.

If you want to see your lawn healthy and avoid rust diseases, you should water the lawn as much as 1-2 inches of rain in a week. This is quite a lot if you have a large lawn area. You should water the lawn in the morning and let it soak in the sunlight for optimal results. This will help the lawn grass grow and prevent diseases like lawn rust, pink patch, and other ground-based fungal infections.

If you water at night or evening, the soil will remain damp, and surface moisture will stay in the ground the whole night. This is more than enough for fungus to breed and donate to the area.

So, you should water the lawn adequately at least once a day a week; it will take an hour or more. To measure the water, you can put a tray or bowl on the lawn while watering. If it goes over 2 inches, you should stop watering.

5. Apply Fertilizers


Apply FertilizersFertilization is among the top most part if you want to prevent potential grass rust disease. This is specifically needed more in the spring and autumn seasons. In spring, try to give a summer or spring-based slow-release type fertilizer in the soil; this will keep up the nitrogen levels for a long.

Then, you should apply a nitrogen-enriched autumn fertilizer as required in the autumn. Don’t apply too much and try to avoid liquid fertilizers in drought conditions, as they could scorch the grass and hamper the lawn’s growth. Keep in mind that you must keep the nitrogen levels of the lawn’s soil to the peak level to prevent grass rust disease. In low to moderately warm weather, you can use nitrogen-rich liquid fertilizers.
