Lawn Aeration Basics Knowing More on Lawn Care
In general, the greater the clay content of your soil, the greater the need to aerate. Clay soil tends to bond very tightly, causing less air space. The act of aerating breaks down those bonds.
Another consideration when deciding whether to aerate is the amount of soil compaction due to traffic. Areas with a lot of foot traffic, such as ball fields, often require more frequent aeration. New construction sites often are compacted due to trucks having driven over the ground numerous times. If your lawn has a low area that tends to hold water, that area should be aerated regularly.
I am often asked how often aeration should be done. The answer depends on the degree of compaction. The average lawn should be aerated once a year. Problem areas can be aerated more often, and as often as once every two months.
There are three basic methods of aeration: tine, core, and liquid. Tine aeration is simply poking holes in the ground with a solid spike. Tine aeration is the least desirable method and many lawn experts feel this method may actually increase compaction.
Core aeration is the actual removal of plugs of soil from the ground. The cores, about the size of your finger, break down and become a part of the soil again. Core aeration is the most used method and is effective.
The last method of aeration is liquid aeration. This method is that the least known, but in my opinion, the simplest method. Liquid aeration is accomplished by spraying a liquid solution over the bottom, then watering it in. the advantages of using this method over core aeration are many. there’s less mess, no cores within the awn. The liquid, when water in, works to a depth of up to 12″, versus 3″ for core aeration. Another benefit is that the liquid is often used everywhere, whereas the coring is restricted around sprinkler systems, tree roots, etc. the merchandise I prefer to use to try to liquid aerations is Aerify Plus.
Aeration can be done anytime the lawn is not frozen. I recommend aerating in the spring or fall so that the grass can recover.
