How To Fix Brown Patch In Lawn
- To prevent spots caused by the nitrogen in dog urine, create a mulch or gravel area in your yard for your dog.
- If your brown spots appear after you mow, check your mower blade. Dull blades shred the grass, which damages the ends that then turn brown.
- In midsummer, check for grubs. And if you find them, apply a grub control product to your lawn.
- Brown patch fungus grows in circular patterns sometimes several feet wide and is generally found during hot, sticky weather. Treat your lawn every other week for 6 weeks with a lawn fungus control product. And water just once a week, since a wet lawn encourages the fungus.
- If you have broad patches of brown, you could have overfed your lawn. Water the burned area every 3 days with at least one-half inch of water for about 4 weeks. And dont fertilize again until the area perks back up.

What Is Red Thread Lawn Disease
Red thread lawn disease is a fungal infection caused by Laetisaria fuciformis. The earliest signs of red thread are often brown patches in the grass, followed by thin, red or pink strands of fungus. These threads may be hard to notice at first, but as the infection progresses, they become difficult to miss.
Red thread is most prevalent in perennial ryegrass, but it can affect most common lawn grasses. It thrives in damp conditions, especially in lawns with poor soil drainage. Soil with low organic matter is also more prone to developing red thread. Grass thats already weak, sick, or malnourished has more difficulty fighting off infections, leading to more severe cases.
Its not uncommon for lawns to see a small patch of red thread, particularly during rainy seasons. Lawns can often recover from these on their own, with minimal intervention. However, more severe or frequently recurring cases need treatment.

This means mowing it weekly during the growing season and removing no more than one-third of the grass blades during any single cut.

What Causes Red Thread
Red thread is a disease of turfgrass that is often associated with under-fertilized turf and one of the simplest recommendations to alleviate disease pressure is to fertilize. But it goes deeper than that.
Red thread loves Michigan summers. The days get very warm and the nights are cooler. These temperature changes often create a moist environment that fungi love, and its a perfect opportunity for them to invade your lawn. The red thread also favors cool-season grasses, such as Kentucky bluegrass, tall fescue, fine fescue, and perennial ryegrass.
Options For Chemical Control
Because improving your lawns health is typically enough to get rid of lawn rust, applying fungicide isnt generally recommended. Lawn rust wont kill your grass, and even if you cant get rid of it this season, your lawn will still be able to produce healthy grass by next summer.
Whats more, the fungicides that work best on lawn rust, DMI and QoI , are usually available only to landscaping professionals.
If you decide to go the chemical route, though, fungicide should be used only on a well established lawn and only after your other lawn care efforts have failed. Apply the fungicide before the lawn goes dormant for the winter. Most lawn rust infections clear up with just one treatment.
Newly seeded lawns are an exception. For these, apply fungicide at the first sign of lawn rust to prevent the fungus from taking hold.
When the conditions for it are just right, lawn rust can make frequent appearances. If you live in a climate with cool springs and warm, bright early summers or you have a shady lawn in heavy clay, you might find this orange blight showing up every year.
In this situation, its reasonable to apply a fungicide to keep the fungus under control. A professional gardener or landscaper can advise you on the best type for your lawn.
However, the success of fungi control using natural methods depends on the severity of the infestation, grass type, and your routine lawn care practices.

- How to Identify and Treat Red Thread Lawn Disease
A red thread is just one of many lawn diseases that can quickly get out of control if left untreated. At Earth Development, we work with businesses across the Midwest to maintain healthy lawns, and our deep knowledge of red thread lawn disease means our clients enjoy healthier greener lawns.
Letâs take a look at how you can spot this disease, how to prevent it, and how to treat it.
How To Prevent Red Thread In Your Lawn
The best course of action to prevent red thread from appearing in your lawn is regular maintenance and garden hygiene.
Over time your lawn can become compacted due to heavy rains, overwatering and constant foot traffic, making it harder for water to go through. Lawns with poor water retention levels are more vulnerable to fungal attacks. The increased humidity in the turf, in combination with high temperatures, creates a perfect ground for fungi to strike. Aerating your lawn can help with water transmission and air penetration.
Heavy layers of cut grass create ideal conditions for fungi to thrive. After mowing, always dispose of the cuttings that you dont plan to compost. Grass cuttings from a diseased lawn should not be used in compost, as it can once again spread the disease. Moreover, if your lawn had a red thread outbreak, make sure to remove and clean your lawnmower brushes to reduce the chances of re-infecting the lawn.
Ensure that the soil has sufficient levels of nitrogen by regularly feeding your lawn with nitrogen-rich fertiliser.

The Development Of Different Fungi
The characteristic arrangement of the fungus in the form of charcoal circles results from the fact that the mycelium grows circularly. Its gradually enlarging the area covered. The hat fungi always grows on the edges of the mycelium formed on the enlarging circle.
During the first period of development, the circles may be invisible. They can also reveal themselves as a clump of grasses with an intense green color or a clump of hat fungi. In the later period, the circles of different sizes are observed. They can reach up to several feet in diameter.
This circle of fungus can grow on the lawn for years. It does so until it encounters an architectural barrier such as the wall of a building or environmental factors unfavorable to the further development of mycelium. Sometimes the fungus on the lawn disappears, only to reappear after a year or two.
Hat fungi most often appear on perennial lawns that have not been regularly or properly maintained. Their appearance is favored by the presence of rotting, slowly decomposing organic matter. These can be the remains of uncut mown grass. They are forming the so-called felt and limiting the access of air to the grassroots.
Very often these are also plant residues and pieces of branches that have not been removed from the ground before the lawn is established.

Other forms lie dormant until autumn when conditions become wetter than normal.
When you notice the first signs of rust disease, it is important to act immediately. Lawns are most susceptible when they experience inconsistent watering or become over-wateredthis can lead them into more serious problems like stunting roots and lowering nutrient reserves which may cause a lack in nutrients such as iron . If Rust Is Currently Uncheckedor if symptoms have started appearing on your lawn but dont yet look severe enough to indicate an emergency situation has begun), begin watching out near shady areas with compacted soil newly seeded patches that havent been established properly due to heavy traffic before planting time.
