Turning yellow grass green involves addressing the underlying cause of the discoloration. Often, this is a nutrient deficiency, particularly nitrogen and iron. However, other factors like pests, disease, or improper lawn care can also contribute.
Diagnosing the Problem
Before applying any treatment, determine why your grass is yellow. Common causes include:
- Nutrient Deficiencies: Lack of nitrogen is a primary culprit, resulting in pale or yellow blades. Iron deficiency also causes yellowing, especially in the newer growth. (Sources: LawnStarter, Hunker, PropertyClub)
- Pests and Diseases: Grubs, armyworms, and various fungal diseases can damage grass, leading to yellowing. (Source: Scientific Plant Service)
- Improper Watering: Both underwatering and overwatering can stress grass, causing it to yellow. Deep, infrequent watering is best. (Source: Hartney)
- Incorrect Mowing Height: Mowing too short can stress the grass, making it more susceptible to yellowing. (Source: Reddit r/lawncare)
