Intro: Yellow grass looks worrying, but the cause is usually simple and easy to fix.
1. Check watering
Too much or too little water causes yellowing. Aim for deep watering once or twice a week.
2. Look for pet urine spots
Dog wee creates small yellow patches. Water the area immediately to dilute it.
3. Check for compaction
Hard soil stops roots breathing. Use a garden fork to aerate.
4. Feed the lawn
Lack of nutrients causes pale grass. Use a general lawn feed.
5. When to get help
If large areas yellow suddenly, it may be a fungal issue.
Summary: Most yellow lawns are caused by watering issues, compaction, or lack of nutrients.
