Lawn Aeration

Lawn Aeration is a process that perforates the soil with small holes that allow water, air, and fertilizer through to get closer to the roots. This enables the roots to grow deeply, producing a healthier more vigorous lawn. Your lawn shows signs of stress and the need for aeration if it doesn’t turn green after fertilizing, or there is a presence of many worn areas throughout your lawn. Lawns only need to be aerated about once a year, and some, if they are only receiving moderate maintenance, need aeration about every two years. If your lawn has a problem with thatch (the composting grass from past mowing), it may be necessary to aerate a couple times a year instead of once as required by most lawns.

Thatch eventually forms a layer that acts as a barrier over the soil. Using a lawn aeration device to break through the thatch is much easier and less drastic than dethatching the entire lawn. An aeration device consists of a special tool that removes plugs from the soil. They’re available in motorized or manual tools, however, unless you’re aerating a small area, the manual tool is not recommended. These can usually be rented from landscaping companies or a tool rental store at a reasonable rate. There are two types of tools that are marketed as lawn aerators. One will simply punch holes in the soil, but will not remove plugs. This will only compact the soil around the holes and the holes will probably fill back in quickly. It’s recommended that you use the type that will actually remove the soil plugs, instead of poking holes in the soil.

An effective tool should produce holes at least three quarters of an inch in diameter and penetrate three inches deep. Also, the plugs should be no more than three inches apart. Aerate on a day that the ground is moist, but not soppy. If you aerate soil that’s too wet, or too dry, the aerating device will not penetrate the soil fully. The plugs that are left behind with aerating can be disposed of a couple ways. The best is probably just leaving them on the surface to dry for a day, and then mowing them to provide a beneficial top layer to your lawn. Other ways of disposing are raking them to break them up after they’re fully dried, or leaving them in your lawn to break down naturally. However, leaving them can make your lawn unsightly for a couple weeks, while the plugs are breaking down.
