Regular stripe
A straight band more often follows a spreader, mower wheel or uneven irrigation.
Lawn problems
Yellow patches in a lawn
Yellow patches can follow drought, fertilizer burn, pet urine, disease or damage below the surface.
Circle with a green edge
This pattern can fit a dog urine spot.
Dry raised area
A section of soil that dries quickly yellows before nearby turf.
More useful detail
How to narrow down the cause
Compare after rain
Drought-stressed turf may change after watering, while dead fertilizer-burned tissue stays dry.
Review recent work
Dates of feeding, spraying and irrigation failures can link the symptom to a specific event.
Problem
What to do step by step
- 1
Take a wider photograph that preserves the shape of the patch.
- 2
Check soil moisture and review work completed over the previous few days.
- 3
Correct the confirmed cause, then plan repair for active growing conditions.
Observation
What to watch next
- The yellow area stops expanding.
- Fresh grass emerges evenly.
- Fertilizer and water reach the turf at even rates.
Important
Do not add fertilizer to yellow turf until fertilizer burn and drought have been ruled out.
