Thatch is a layer of living and dead organic matter that occurs between the green matter and the soil surface. Excessive thatch (over 1/2 inch thick) creates a favorable environment for pests and disease, an unfavorable growing environment for grass roots, and can interfere with some lawn care practices. This material doesn’t break down satisfactorily over time and contribute to a thatch layer that can affect the absorption of vital nutrients to support your lawn. Further, when new grass cannot reach the soil, it sends its roots into the thatch, which has very little nutritive value.  Thatch prevents the grasses root system from receiving the proper amount of nutrients to help maintain a healthy lawn.

What Causes Thatch?

Thatch problems are due to a combination of biological, cultural, and environmental factors. Cultural practices can have a big impact on thatch. For example, heavy nitrogen fertilizer applications or overwatering frequently contribute to thatch, because they cause the lawn to grow excessively fast. Avoid overfertilizing and overwatering

Signs Of Concern

If your lawn shows any of the following signs - you could be at higher risk of thatch related problems.

• Lawn showing considerable foot wear
• Drains slowly
• Browns up quickly when dry

Is A Little Thatch OK?

Absolutely! A desirable amount of thatch is under half an inch – this amount is sufficient to protect your root system from nature’s element extremes without causing a lack of breathing room for the root system; further this amount of thatch allows for a cushioning on the lawn to help stand up to traffic
