Why Fall is the Best Time to Aerate Cool-Season Grasses

Fall is the best time to aerate cool-season grasses and prepare them for next spring.

Fall is the best time to address several lawn issues now that the heat of the summer is gone. During the summer, your lawn may have experienced drought, excess moisture, compaction, disease, or insect infestation. Any of these issues can impact the lawn throughout the following seasons. Fortunately, aeration can help alleviate some problems. Cool-season grasses like Kentucky Bluegrass and Tall Fescue are actively growing in the fall, so it’s a great time to aerate. After you aerate cool-season grasses, you can apply pre-emergent fertilizer to increase the health of your lawn. If you haven’t aerated your lawn in the past two years, consider the following ways this practice can positively impact your lawn. 

Aeration Regenerates Root Systems

The primary reason to aerate cool-season grasses is to regenerate the root system. The roots supply the necessary oxygen, water, and nutrients your turf needs. Aeration opens up channels allowing oxygen directly to the roots. These channels also work as a funnel that allows water and nutrients to reach the roots, and the aerated space creates an undisturbed area for the roots to grow. 

Aeration Oxygenates Microbes in the Root Zone 

Oxygen is needed by the microbes that live in the root zone. These microbes not only deliver nutrients but eliminate waste that the turf secretes and reduces thatch buildup. Without the microbes, you would not have a survivable landscape. 

It’s Easier to Change the Soil Chemistry 

When you aerate cool-season grasses, it creates a more direct way to add nutrients that positively affect the soil chemistry. For instance, if a soil sample shows that the soil is low in calcium, aeration can help you introduce calcium directly into the soil. It’s more effective than applying it on top because it allows the nutrients to reach the root zone faster and reduces runoff of fertilizers.  

Removes Thatch 

Aeration is a great way to reduce excessive thatch from your lawn. Thatch often results from excess watering and high amounts of water-soluble nitrogen. If your thatch is greater than 3/4” more than one aeration session a year may be required. 

Aeration Helps New Seed Take Root

When overseeding an existing lawn, core aeration helps create a good seedbed for that new seed. It can give the seedling uncompromised room to exist and take root.  

Aeration can significantly benefit your lawn. If you want to give your yard a boost before winter sets in, aerate your lawn this fall.
