Rust
Also called Lawn rust, turf rust
A fungus that puts orange to reddish-brown powder on grass blades. It tends to hit lawns that are stressed.
How to spot it
- Small orange to reddish-brown flecks on the blades
- Flecks grow into raised, oval or elongated pustules
- The orange to brown powder rubs off easily
- Older pustules turn brown to black
- Bad cases leave thin, yellow-orange to reddish-brown turf
Why it shows up
Rust likes warm, humid weather. It hits grass that's stressed by drought, low nitrogen or shade the hardest.
How we treat it
We'll identify it on a visit and recommend the right fix. It's mostly a lawn-care fix: keep the grass fed so it keeps growing, avoid drought stress and overwatering, and mow at the right height. If it keeps coming back, a treatment might make sense, and we'll talk through it with you.
What you can do
- Keep up with feedings. Low nitrogen invites rust.
- Water deep when the lawn needs it. Don't let it dry out too far.
- Mow at the right height for your grass.
