Lawn turning yellow is a common issue for UK homeowners, especially during warm or dry weather. While it looks worrying, most causes are easy to fix once identified.
This guide explains the most common reasons grass turns yellow and what you can do to restore a healthy green lawn.
Is a yellow lawn always a problem?
Not always. Temporary yellowing can happen during drought or cold spells. However, widespread discolouration usually signals stress.
Common causes of yellow grass
1. Lack of water
Dry soil causes grass to go dormant and turn yellow.
2. Overwatering
Waterlogged roots suffocate and weaken grass.
3. Nutrient deficiency
Lack of nitrogen causes pale yellow blades.
4. Dog urine
High nitrogen patches burn grass.
5. Lawn disease
Fungal infections cause yellow patches.
6. Compacted soil
Roots struggle to access air and nutrients.
