Sometimes, a walk through your lawn leaves an orange-brown coating on your shoes. The coating looks like rust, and this may indicate that your lawn has a fungal infestation. If you have been asking what the rust-colored dust on your lawn is, this article is here to provide you with the answers you seek.

We will first explain what that rust is, the causes, and how to treat and prevent its reoccurrence.

What Shows the Presence of Lawn Rust on Your Lawn?

The first sign that shows that the grass on the lawn suffers from rust is when there is a tell-tale sign of rust-colored powder covering the blades of the grass. The rust-colored powder brushes off easily, and you will notice it on your shoes, clothes, and even your pets’ fur.

In the early stages, lawn rust is noticeable through the yellow dots on grass blades. Sometimes, it looks like sunlight is hitting the grass at an angle, but the yellow dots emerge strongly on closer inspection.

The final sign is that lawn rust weakens and thins the grass. Your lawn will obviously look unhealthy, and the grass blades will break easily.

Are There Specific Conditions That Influence the Spread of Lawn Rust?

There are specific conditions that hasten the spread of lawn rust. One of the causes of rust on grass is fungi, but other factors influence how it spreads from one end of the lawn to the other. Some of these factors include:

  • The Season of the Year: Lawn rust spreads faster when humidity and temperatures are high, and that is common during summer and early fall.
  • Moisture Levels: Lawn rust thrives when the ground is moist, which is common during heavy rains or in the morning when there is dew.
  • Weather: Humidity and indirect sun make for ideal conditions for the spread of lawn rust.
  • Grass Species: Certain grasses, such as tall fescue or Kentucky bluegrass, are very susceptible to lawn rust.

How to Get Rid of Lawn Grass

Contrary to popular opinion, Lawn Rust doesn’t use fungicides as the treatment of choice. If you are seeking answers on how to get rid of lawn rust, you should:

  • Reduce watering to eliminate the moisture that lawn rust needs to thrive.
  • Fertilize your lawn to add nitrogen to the soil and make it less suitable for lawn rust.
  • Prune other plants to eliminate the shade the lawn rust needs to spread.
  • Improve your lawn’s aeration to eliminate excess moisture from the soil.
