How to Aerate a Lawn with a Core Aerator
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.
What is Lawn Aeration?
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
your yard.
Helps air, water and nutrients get into the root zone
Increases/stimulates grass root growth
Opens up the soil so amendments can be added
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.
How to Aerate Your Lawn
You can rent a lawn aerator at most equipment rental shops.
Water your lawn the night before to ensure good soil moisture. You will want the soil to be moist not wet!
Mark Sprinkler Heads
Mark all irrigation heads, valve boxes (and anything else that you don't want to poke holes in) with flags.
Core Aerator
Try to run the aerator over your lawn in at least three directions. Poke a lot of holes for best results.
Pull lots of plugs to get the most benefit
Now's the perfect time to overseed and compost topdress.
The plugs will disappear in a couple weeks. Leave them on your
lawn, the soil that you bring to the surface will help break down
thatch.
The cores will be gone in a couple weeks
If you aerate in the spring and you plan on using a preemergent crabgrass preventer -- aerate before
you apply your preemergence or you will reduce its effectiveness.
Remember, crabgrass preventer also works on grass seed - don't use it if
you overseed!
