Dethatching is the process of removing excessive thatch-a dense layer of dead and living organic material such as dead grass, roots, and debris-that accumulates between the soil surface and the grass blades. While a small amount of thatch can benefit the lawn by providing nutrients and moisture retention, too much thatch creates a barrier that prevents air, water, nutrients, and sunlight from reaching the soil and grass roots

. What dethatching does:

• Removes the thick thatch layer that can make the ground spongy and unhealthy

• Improves airflow and water absorption to the soil and roots

• Enhances nutrient uptake, helping fertilizer reach roots more effectively

• Encourages deeper and stronger root growth, making grass more resilient to drought, pests, and disease

• Controls weed invasions by promoting healthier grass growth

• Improves soil health and reduces compaction, especially when combined with aeration

• Helps winterize the lawn and improves its overall appearance and vigor

Dethatching is typically done using specialized equipment or a powerful rake to physically remove the thatch layer. It is recommended to dethatch during the active growing season of your grass type-cool-season grasses in early spring or late summer/fall, and warm-season grasses in late spring to early summer

. In summary, dethatching revitalizes a lawn by clearing away excessive organic buildup that suffocates grass roots, thereby promoting a healthier, more vibrant, and resilient lawn
