A healthy, green lawn enhances your home’s curb appeal, but yellow patches can be frustrating. Identifying the causes of yellowing grass and implementing effective solutions can restore your lawn’s vibrancy.

Common Causes of Yellow Grass

1. Lawn Grubs

Lawn grubs feed on grass roots, leading to yellow patches. Common culprits include billbugs and white grubs. Control these pests with appropriate insecticides.

2. Lawn Fungi

Fungal infections like Ascochyta and Necrotic Ring can cause yellowing. Ascochyta appears after hot weather following rain, while Necrotic Ring causes yellow rings. Aerate, mow properly, and overseed with resistant grass varieties.

3. Watering Issues

Both overwatering and underwatering can result in yellow grass. Water deeply but infrequently to promote deep root growth.

4. Compact Soil

Compacted soil hinders root growth, causing weak, yellow grass. Aerate the soil and dethatch to improve its condition.

5. Animal Urine

Pet urine can burn grass due to high nitrogen content. Train pets to use specific areas or dilute the urine with water. Overseed damaged areas.

6. Nitrogen Fertilizer Overload

Excess fertilizer burns grass, turning it yellow. Water thoroughly to dilute the fertilizer. If recovery is slow, rake and overseed.

7. Nutrient Deficiency

A lack of essential nutrients can cause yellowing. Regular fertilization maintains nutrient levels, but avoid over-fertilizing.

8. Mowing Problems

Mowing too short or with dull blades can damage grass. Keep mower blades sharp and avoid cutting grass too short, especially in hot weather. Maintain a height of about 3 inches.

9. Dry Weather

Hot, dry weather can yellow grass. Cultivate a deeply rooted lawn and follow proper watering guidelines to withstand dry conditions.
