Lawn Aeration in Cottleville, MO
Fall core aeration and overseeding for Cottleville lawns on clay, from Cottleville Trails to Ashford Knoll. About fifteen minutes from our O'Fallon shop.

Aeration in Cottleville
Cottleville is about fifteen minutes from our shop at 2743 Hwy P in O'Fallon. The subdivisions off Highway N were built on compacted clay in the 1990s and 2000s, and the trees planted then are now big enough to shade the fescue underneath. That combination, hard soil plus growing shade, is why Cottleville lawns come out of summer thinner every year unless they are aerated and overseeded in fall.
We core aerate the whole lawn, overseed with a turf-type tall fescue blend, and apply starter fertilizer in a single September or early October visit. Where the clay is hardest we make a second pass in the other direction. Sprinkler heads and invisible fence lines are flagged before we start, and the cores break down on their own in a couple of weeks.

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

Get on the fall list
September and early October are the window for Cottleville 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.
Maturing shade in Cottleville yards
The maples and oaks in Cottleville Trails and Prairie Bluff cast far more shade now than they did ten years ago, and the fescue under them needs a shade-tolerant blend and a taller cut. We adjust the seed mix by what the yard actually looks like, go heavier under the trees, and tell you what to expect. Many Cottleville subdivisions are HOA-maintained on the common ground, and a thick lawn keeps your yard in line with it.
What aeration costs in Cottleville
Aeration in Cottleville 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.
