Aeration improves the soil contact and ensures the success of over-seeding. It also combats thatch buildup, poor drainage and soil compaction. Like all living things, your grass requires air, food and water. Aeration opens up the surface of the soil and helps the oxygen, nutrients and water reach the roots. In any case, aerating before fertilizing, seeding or applying crabgrass preventive helps to maximize the treatment’s effectiveness.
Excessive thatch build up is usually the biggest threat to a homeowner's lawn. Thatch is composed of intermingled layers of living and dead stems, leaves and roots between the green vegetation and the soil surface. Practically speaking, thatch is an organic material that does not decompose. A thin layer of thatch is normal, even healthy, since it retains some moisture in the soil and increases wear tolerance. However, a thatch layer of ½ inch or more, prevents air, light, and water from reaching the turf's root zone. As thatch accumulates, there is a tendency for root growth to occur primarily in thatch layer rather than the soil. This results in a weakened, poorly rooted turf that is prone to stress injury. Thatch also makes an excellent breeding ground for harmful insects and disease organisms.
Dethatch the turf so that all the nutrients and water your grass needs can get down into the soil. It will make the grass lush, healthy, and beautiful. This service is recommended once to every three years. After this extreme winter it will be common to have a thatch layer over a 1/2 inch.
We use a professional power rake to comb out the right amount of dead materials. Our machine has a six wheels with over 52 revolving vertical blades per wheel that slice down through the grass and thatch evenly to the soil.The thatch is raked off the turf and hauled away. After thatching, it’s also a good time to aerate the turf, apply fertilizer, and or over-seed.
