Lawn aeration improves growing conditions resulting in a healthy, vigorous lawn. It is the best way to cultivate and improve the soil without harming your lawn.
I highly recommend aerating at least once a year, besides mowing, watering and fertilizing, it is the best thing you can do for your lawn.
The best time for this chore is when your grass is actively growing.
This is in the fall or early spring for cool-season grasses, however fall is the preferred time to core aerate if you do only once.
Early summer is when warm season
grasses start to grow and is the best time to aerate southern lawns.
Supplying the soil with air or exposing to the circulation of air.
Healthy soils need to "breathe". The process of aerating a lawn is
accomplished by removing small soil plugs (or cores) with a machine.
Coring improves the soil (or cultivates the soil) without destroying
Tip: aerating before overseeding will yield great results. The grass seeds find their way into the holes where they find very favorable conditions and germinate quickly. The seeds are protected, stay moist and make good contact with the soil. In a week, you will see grass seedlings growing in all the holes!
QUESTION: Why is coring - or removing plugs - better than spiking?
The holes made by spikes close up quickly while the holes from coring a last long time.

Pull lots of plugs to get the most benefit
The cores will be gone in a couple weeks
