What Causes Rust-Colored Dust On Lawns?

If you’re walking around your neighborhood and notice rust-colored dust on lawns (including your own), don’t fret. Lawn rust (also called grass rust) is a common problem many homeowners experience at one point or another. But understanding what it is and how it develops will help you keep those small yellow patches from developing around your home.

What Is Lawn Rust?

Lawn rust does not develop like the rust you find on your car or an old swing set. In this case, the rust is caused by a common lawn fungus.

Rust-colored lawn dust is also known as lawn rust.

Lawn rust typically starts showing up in the late summer or early fall. It is a fungal lawn disease that is often triggered by the stress of shorter days and periods of cool, wet weather.  

What Causes Lawn Rust?

In conjunction with these conditions, lawn rust is often a result of several additional factors. They include:

  • Overwatering your lawn
  • Thatch build-up 
  • Deficient nutrient levels 

Watering your lawn is important to keep it thriving, but too much water can lead to trouble because warm, moist, humid weather creates the perfect environment for rust fungus to develop.

Thatch is a common and quite unsightly lawn problem. Thatch occurs when a layer of partially decomposed grass parts (roots and stems) build up into what looks like a thick mat on the surface of the ground. Gra

An important part of lawn care is fertilizing. Lawn fertilization ensures that your grass and soil are getting all of the nutrients they need to thrive. In the case of lawn rust, your lawn will most likely need nitrogen added.

What Types of Grass Are Affected?

Lawn rust infections can occur with almost any type of grass, including: 

  • Kentucky Bluegrass
  • Perennial Ryegrass
  • Tall Fescue

If you’re not sure what type of lawn you have, you’ll find that treatments are generally the same for all types, but it is best to check with a local lawn care company to ensure you are using the right product for your lawn.
