Aerating your lawns is one of the most beneficial things you can do to create and maintain a lush, healthy, green, weed free lawn. Deep Core Aeration is performed by a roto-tiller type machine that uses hollow tines to remove "plugs" or cores of soil. These plugs should ideally be ¾ of an inch in diameter and 3 inches in length. The plugs are left on the lawn and break down after time, mowing, and rainfall. The plugs return valuable nutrients and microorganisms to the soil, and should be left on the lawn, not raked up and thrown out.

Benefits

Aeration creates many benefits for your lawn. Aeration opens up the root zone by creating more spaces of air in the soil. Because roots grow in the spaces of the soil, rather than in soil itself, it encourages a deeper, more extensive root system. The deeper the root system, the healthier your lawn will be. Aeration also allows for better transfer of air, water and nutrients to the root zone. Deep Core Aeration pulls thatch-eating microorganisms from deep in the soil to the surface. If your soil is compacted, Deep Core Aeration is an excellent method of relieving soil compaction. Applying PH adjustments after aeration enables the lime or sulphur to penetrate deeper into the soil. This in turn allows nutrients to get deeper into the root zone. If your lawn requires over-seeding, aerating will greatly enhance seed-to-soil contact. The holes left behind by the plugs provide a protected environment essential for germination and growth.

When is the Best Time to Aerate

Spring or fall is the best time to aerate your lawn, however a lawn can be aerated anytime during the growing season. Traditionally, people like to aerate in the spring so the lawn will benefit during the upcoming season. However, more and more people are switching to a fall aeration for cosmetic reasons. Aerating just before snowfall means you don't have to look at the plugs on your lawn, and they will be gone when spring arrives.

If your thatch layer is more than ¾ of an inch but less than 2 inches, you should consider aerating twice in one year. If your thatch layer is over 2 inches thick, alternative methods must be used to reduce the thatch layer. Quite simply put, deep core aeration is one of the homeowner's greatest assets in creating a beautiful, lush lawn.
