Dethatching Vs Aerating Lawn

Aerating with a core aerator as opposed to dethatching may seem a preferable option to solving your thatch problems on paper, but theyre two completely different lawn care processes. Both procedures are geared towards creating healthy lawns and enhancing the breathability of the soil and the ability of the grass to soak up the essential nutrients, and promote root growth, but the two processes help your lawn in different ways.

Dethatching, as the name suggests, is the process of removing thatch from the soil surface. Thatch however does offer certain key benefits for your soil such as retaining soil moisture by acting as a mulch, providing a constant infusion of nutrients, as well as insulating the soil from temperature extremes.

Thatch only becomes a problem when the tightly intermingled layer is too thick, causing the grass roots to suffocate, thereby killing the healthy grass. Thatch that is too thick should be dethatched leaving only a healthy thin layer on the soil surface.

Lawn aeration is similar to dethatching in that it helps the soil under your lawn to breathe, but it is a procedure that helps control thatch rather than actually get rid of an excessive build up.
