Aeration, also called coring or aerifying, is the best way to reduce thatch. Thatch is a tangled mat of organic matter that accumulates in your lawn. 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 90% moisture.
Some thatch is perfectly normal. However, excess thatch creates a host of problems that includes shallow root development, nutrient imbalances to 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 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. 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.
The problem with too much thatch:
- Prevents water from being absorbed
- Provides an ideal location for many pests
- Provides an ideal location for lawn diseases to incubate
- Interferes with seeding, feeding and pest control
