What is lawn aeration?  Lawn aeration involves perforating the soil with small holes to allow air, water and nutrients to penetrate the grass roots. This helps the roots grow deeply and produce a stronger, more vigorous lawn.


The main reason for aerating is to alleviate soil compaction. Compacted soils have too many solid particles in a certain volume or space, which prevents proper circulation of air, water and nutrients within the soil. Excess lawn thatch or heavy organic debris buried under the grass surface can also starve the roots from these essential elements.

To understand what dethatching is, you must know what thatch is first.  Thatch is a tightly intermingled layer of living and dead stems, leaves, and roots which accumulates between the layer of actively growing grass and the soil underneath. Thatch is a normal component of an actively growing turfgrass, and as long as it is not too thick, it can increase the resilience of the turf to heavy traffic. Thatch develops more readily on high-maintenance lawns than on low-maintenance lawns.

An excessive thatch layer (typically more than 1/2 to 3/4 inch, depending on the situation) can restrict the movement of air, water, fertilizer and other materials to the roots, all of which are necessary for healthy, vigorous turf growth. Since thatch greatly restricts the permeability of air and water, the grass plants tend to to root within the thatch in an attempt to obtain these resources.  Thatch is a poor growing medium and this process reduces the overall drought resistance of the turf. Furthermore, if the thatch dries out, it cannot be rewetted easily. Even if the thatch stays moist, it can harbor fungi that cause turf diseases. When certain temperature and moisture conditions arise, a disease infestation can kill the already weakened turf.

Thatch that has accumulated to an excessive level is best reduced by mechanical means. Dethatching machines known as vertical mowers, verticutters, dethatchers, or power rakes have vertically spinning blades which pull some of the material to the surface as they slice the thatch layer.  Bluemel's has the necessary machinery to perform this  time consuming task.
