GreenWorks offers competitive prices for core aeration and overseeding. Lawn aeration is an important part of regular lawn maintenance because it loosens soil and breaks up thatch. Aeration is a great way to prepare a lawn for overseeding. Aerated lawns are more drought tollerant and have better access to nutrients, these benefits often cause the lawn to thicken during the months after aeration.
Core Aeration vs Spike Aeration
GreenWorks offers core aeration because it is the most effective type of aeration. Cores of soil are brought to the surface and placed on top. This loosens soil and breaks up thatch. These cores of soil break down over the course of a week or 2 depending on rain and mowing schedule. This method of aeration exposes more of the soil to oxygen in the air which promotes beneficial soil microbes.
Spike aeration is another method of aeration where spikes or tines are pushed into the ground. This loosens soil, breaks up thatch and improves soil/air contact, but the holes quickly get filled in because the soil has just been pushed to the side. This is a good option where cores are not wanted on top of the lawn immediately after aeration.
Aeration and Overseeding
The holes that are created and the cores of soil that are brought to the top make a good foundation for overseeding. New seed will fall in the holes and make contact with the soil cores on the surface. See our article on overseeding for more information.
Breaking up Thatch
Thatch is a layer of organic matter that forms right at the soil surface. Thatch is often difficult to see without digging into the soil. A thin layer of thatch is beneficial to lawns, it helps to retain moisture and creates an environment for beneficial microbes to to exist. A thatch layer should be no more that a quarter of an inch thick.
Thatch layers that are too thick can promote insect and disease problems. Thick thatch layers also make it difficult for water and nutrients to thoroughly saturate the soil. Breaking up the thatch layer with an aerator is a good way to improve water and nutrient saturation and increase soil/air contact which will promote beneficial microbes that further assist in breaking down the thatch.
