What Is Core Aeration?

Core aeration is the process of removing plugs of soil and thatch from a lawn to allow air, water, and nutrients to penetrate the grass roots. This allows the grass roots to grow deeper thus producing a stronger and thicker lawn. This is done by using a machine with hollow tines. It is much more effective than using solid tines that simply make holes in the soil and cause more compaction. By removing plugs of soil you are also allowing the soil to become less compacted. The holes left from the plugs are about 3/4 inch in diameter and about 4 inches deep. These holes will allow more nutrients to get to the grass roots as well as separate the soil.

Common Questions About Aeration

Q: When should I aerate?

A: The best time to aerate is in the spring and fall when the soil is moist.

Q: How often should I aerate?

A: You should aerate your lawn at least once a year. If your soil drains poorly or is heavily compacted aerate twice a year.

Q: Can I overseed my lawn after aeration?

A: This is a great time to overseed. The seed will fall into the holes left from aeration which increases the seed to soil contact.

Q: Should I apply fertilizer after aeration?

A: Yes, fertilizer will give your lawn a big boost now that you have aerated and the grassroots have access to more nutrients.
