Thick, striped fescue lawn after aeration and overseeding in O'Fallon, Missouri

Aeration in our home city

Our shop is at 2743 Hwy P in O'Fallon, so when the aeration window opens in September we can get to O'Fallon lawns quickly and in the right order. Nearly every lawn in the city, from the older streets near Fort Zumwalt Park to WingHaven and the subdivisions along Highway K, is tall fescue growing on clay that was compacted by construction and has been packed harder by every mower pass and summer since.

Core aeration pulls plugs out of that clay so water, air, and fertilizer reach the roots, and it is the only practical way to get new fescue seed into real contact with soil. We aerate the whole lawn in two directions on hard ground, spread a turf-type tall fescue blend into the open holes, and put down starter fertilizer in the same visit.

What our aeration service includes

Core aeration with a machine that pulls plugs of soil two to three inches deep

Two passes in different directions on compacted lawns

Overseeding with a turf-type tall fescue blend right after aeration

Starter fertilizer to push the new seed along

Flagging sprinkler heads and invisible fence lines before we start

Watering and mowing instructions for the first few weeks

Get on the fall list

September and early October are the window for O'Fallon lawns. We schedule aeration in that stretch and confirm the date by text.

Aerate, seed, and feed

The crew pulls cores across the whole lawn, spreads seed into the open holes, and applies starter fertilizer in one visit.

Watch it fill in

Keep the seed damp for two to three weeks, and the thin spots thicken up before the first frost. Cores break down on their own.

Why O'Fallon lawns thin out every August

Fescue is a cool-season grass, and an O'Fallon summer is hard on it. Shallow roots in compacted clay dry out in July, the lawn goes dormant or thins, and by Labor Day there are bare spots in every full-sun yard in WingHaven. Fall aeration and overseeding is how those spots fill back in before winter, and a lawn that gets it every year or two stays thick enough to crowd out crabgrass the following spring.

What aeration costs in O'Fallon

Aeration in O'Fallon is priced by lawn size and quoted for free from a satellite measurement or a quick visit. What changes the price:

Square footage of turf. The base price comes from the lawn area alone. Beds, driveways, patios, and the house footprint do not count.

Aeration alone or with overseeding. Seed and starter fertilizer add to the price, and almost every Missouri fescue lawn benefits from adding them.

Soil condition. Hard, dry clay sometimes needs a second pass to pull a full core.

Bundling. Customers on a mowing or fertilization program get a bundled price on fall aeration.

Lawn Aeration questions from O'Fallon homeowners

Fall, from early September through mid October. O'Fallon lawns are mostly tall fescue, a cool-season grass that grows roots fastest in cool weather, so seed put down in that window establishes before winter. Spring aeration is possible but competes with crabgrass pre-emergent timing.
St. Charles County soil is heavy clay that packs down under foot traffic, mowers, rain, and summer heat. Pulling cores opens the soil so water, air, and fertilizer reach the roots, and it is the only practical way to get new seed into solid contact with soil.
Yes, if the lawn has thin or bare areas. The aeration holes are the ideal place for seed to land, and fescue does not spread on its own, so overseeding every fall or two is how a fescue lawn stays thick.
Wait until the new grass is about three inches tall, usually two to three weeks, then mow high with a sharp blade. Water lightly every day until the seed is up, then taper off.
Yes, in late spring or early summer when zoysia is actively growing, since it is dormant in fall. If you are not sure what grass you have, we can tell you during the estimate at your O'Fallon home.
