What Is Dethatching? Mechanical Dethatching vs. Natural Dethatching

Dethatching is a necessary step in the lawncare and landscape maintenance process. This service removes the dead layer of grass blocking water from soaking into the soil. There are different types of dethatching services, and some are more effective than others. Let’s take a closer look at what dethatching is.

What Is Thatch? What Does Dethatching Do?

Thatch is a layer of dead grass right above the soil. This develops when the lawn produces debris faster than it can break down. Grass natural feeds itself, to a degree, and the debris created puts nutrients back into the soil. However, if the dead layer builds up too thick, it can prevent water and other nutrients from properly penetrating the ground.

Dethatching reduces the thickness of the thatch to revitalize the turf. This gets rid of that tough barrier that’s blocking your soil from getting ‘the good stuff.’ Think of dethatching as an exfoliation process, preparing your lawn for a healthy growing season.

Types of Dethatching: Mechanical vs. Natural

The two most common forms of dethatching are mechanical and natural. Mechanical dethatching uses a machine to rake the lawn and remove the thatch. Natural dethatching involves an organic spray that covers the entire lawn. The spray breaks down the thatch naturally, releasing the nutrients back into the ground.

At Berns Landscaping, we use natural dethatching in our landscaping services. Mechanical dethatching may seem more effective at first glance, but it only removes about 10% of the thatch layer. It damages the lawn, creates more debris to clean, and it costs more to do! Why pay more for a less effective service? You can have thick turf, nutrient-rich soil, and superior plant health, as long as you take the right steps with lawn care.

How Often Should You Dethatch Your Lawn?

For most properties, dethatching happens once a year. However, dethatching is not always necessary, or it may be required more often in certain areas. This is one of the reasons we conduct a soil test once every three years. It allows us to evaluate the thatch layer and determine how thick it is. Once the thatch is thicker than 1/8th of an inch, we will recommend natural dethatching.
