Aeration Services for Better Thatch Control


eration, also called coring or aerifying, is the best way to reduce thatch buildup. Thatch is a tangled mat of organic matter that accumulates on the top of the soil's surface and the lawn's root system. It is actually a tightly intermingled mat of dead and living stems, leaves, crowns and roots that forms between the soil surface and grass blades. Contrary to popular opinion, thatch is not caused by cut grass stems which are about 90% moisture and decompose quickly.

Aeration improves clay soils and reduces soil compaction.

Some thatch is normal and expected. However, in some instances, excess thatch increases to a level that creates a variety of problems including shallow root development, nutrient imbalances, plus it increases the possibility of having insect and disease infestations.

Aerating is one of the best things you can do for your lawn. It improves drainage, stimulates growth, helps relieve soil compaction and increases the effectiveness of fertilizers.

Aeration should be considered at least once a year, and twice if you lawn has a heavy thatch layer or is compacted due to heavy use.

We offer aerating in spring and/or fall based on your lawn's condition. Aeration service can be performed every year on lawns with a heavy thatch layer until the condition improves. Most lawns only need a periodic aeration every couple of years.

Power Seeding

Many times a lawn that has excess thatch, also exhibits thinning. When we aerate the lawn, we can also perform our special Power Seeding application that forces seed into the ground at the right depth for optimum germination. This helps fill in those thin spots you may have noticed in your lawn, especially after a stressful summer.

Note: Aeration services and power seeding are optional services and billed separately from our regular lawn fertilization program.

Aeration explanation

Aeration is the process of removing small plugs or cores, from a lawn. These plugs are about 2 - 3" deep and leave holes about 4" apart. The plugs are deposited on the soils surface where they will disappear in about 2 weeks. It is important not to remove the plugs from the yard as they contain microbes that help break down the remaining thatch.
