Step 1 – DethatchOver time decomposed stems, roots and other organic matter build up between the grass and the soil surface. Some thatch is good but too much can act as an impervious layer which can cause some of the following problems:
- Block water, nutrients and disease controlling insects from reaching the soil.
- Block sunlight from reaching lower grass blades.
- Holding moisture against the grass which can promote disease.
- Cause roots to grow into thatch causing a shallow-rooted lawn
- Create an uneven lawn.
