What Causes Light Yellow Spots in My Yard?

Why Yellow Spots Show Up in Lawns

Light yellow patches in your lawn are one of the most common problems homeowners in Rochester Hills deal with. These spots usually start small and spread over time if the underlying issue is not addressed.

The challenge is that yellow grass is not caused by just one thing. It can come from soil problems, watering mistakes, pets, fertilizer burn, disease, or even underground lawn pests.

Most Common Causes of Yellow Grass

• Overwatering or poor drainage
• Underwatering during heat waves
• Nitrogen deficiency
• Pet urine burn spots
• Compacted soil
• Grub damage beneath the surface

Why Rochester Hills Lawns Are Especially Affected

Michigan weather swings create turf stress and expose weak root systems quickly during summer heat.

Could Grubs Be Causing Yellow Spots?

If your grass pulls up easily like carpet, grub damage may be the real issue.
