Why Aeration and Overseeding Should Be an Annual Part of Your Lawn Care

Seeding and aeration is the single most important thing that you can do for your fescue lawn. We put this blog post together to convince you why to overseed and aerate every year, and why you should let GroGreen do it. 


If you have a tall fescue lawn in the Chattanooga area, summer is tough on it. Heat, drought, disease, foot traffic, and normal wear can cause even a healthy lawn to thin out by the end of the season.


The problem is that tall fescue doesn't spread and repair itself the way grasses like Bermuda and Zoysia do. When individual fescue plants die, they leave behind thin or bare areas. That's why annual aeration and overseeding is one of the most important things you can do to maintain a thick, healthy fescue lawn.

Why Overseed Every Year?

Think of annual overseeding as youthful rejuvenation for your lawn.


Every summer, some fescue plants are lost because of our brutal heat. Overseeding introduces new grass plants to replace those losses, fill thin areas, and maintain a dense stand of turf. A thicker lawn also leaves less room for weeds to become established.


But there's another important benefit: grass seed keeps getting better, and GroGreen makes sure that only the best seed goes into our lawns.


Turf breeders continually develop improved tall fescue cultivars. By overseeding every year with high-quality seed, we can introduce newer varieties into your lawn that offer darker green color, improved drought tolerance, better disease resistance, and better overall performance than many older varieties.


Instead of allowing your lawn to slowly decline as older grass plants disappear, annual overseeding gives you an opportunity to continually improve it.


Why Aerate Every Year?

Over time, soil becomes compacted from foot traffic, mowing, rainfall, and everyday use. Compacted soil makes it harder for grass roots to get the water, oxygen, and nutrients they need.


Core aeration removes thousands of small plugs of soil from the lawn. This relieves compaction and opens the soil, allowing water, air, and nutrients to reach the root zone more easily.


Aeration also creates ideal conditions for overseeding. The holes and disturbed soil provide much better seed-to-soil contact than simply spreading seed over the surface.


Why Choose GroGreen for Aeration and Overseeding?


There are plenty of companies that own an aerator and can spread grass seed.


At GroGreen, grass is what we do. Lawn health is our specialty.


We spend every day working with Chattanooga and cleveland lawns. We understand turfgrass, soil, fertility, weeds, insects, disease, and the challenges our climate creates for tall fescue.


More importantly, we understand how grass needs to be planted.


Successful overseeding isn't just about putting seed on the ground. Seed selection, application rate, timing, aeration, seed-to-soil contact, watering, and what happens to the lawn before and after seeding all affect the final result. We also touch any thin spots in our late fall and early winter treatment visits.


Our goal isn't simply to complete an aeration and seeding service. Our goal is to grow grass. Better grass means fewer weeds.


We Want Your Neighbors


There's another reason we care so much about how your lawn turns out:


We really want your neighbors.


Your lawn is GroGreen’s best advertising. We’re a small, local, independent company with a limited marketing budget, and your lawn is our billboard, and our customers have always been our best salespeople. Our best lawns are the ones who let us aerate and overseed.


We want your lawn to be the one your neighbors notice. We want them asking you why your grass is thicker, greener, and healthier and who takes care of it.


That gives us a pretty strong incentive to do the job right.

Don't Wait Until Your Lawn Is Thin

Aeration and overseeding shouldn't be something you only consider once your fescue lawn starts looking bad. In the Chattanooga area, it's best viewed as annual maintenance for a healthy fescue lawn.


Each fall gives us an opportunity to repair summer damage, relieve compaction, introduce improved grass varieties, and prepare your lawn for another year.


Summer takes some of your fescue every year. Aeration and overseeding puts it back, and gives us the opportunity to make the lawn even better than it was before.


Let GroGreen take care of it, because it’s what we do best.
