Lawn Dethatching

Dethatching also known as power raking is nothing more than removing the matted layer of dead grass that accumulates between the soil surface and the good green grass blades. Over time, it forms a thick layer, limiting water, nutrients, and air from reaching the root system. A thick thatch layer is known to provide the perfect environment that can encourage pests and diseases. The process of dethatching is hard on turf, so the ideal time to tackle this chore is during the spring and fall due to the cooler temperatures.

How do I know if i need dethatching?

Thatch build up is most of the times easily visible at close inspection, if your lawn feels spongy or bouncy underfoot, your lawn needs dethatching. To make sure, run a garden rake through the grass, if you are able to rake dead grass blades, debris or thatch build up, its time to dethatch your lawn.

What causes thatch build up?

The primary reasons for thatch to accumulate are applying heavy nitrogen fertilizer applications and excessive watering which causes  lawns to grow excessively fast. Turfgrass stems and roots accumulates faster than they breakdown. Another reason thatch starts to build up is poor quality soils, and soil compaction.
