Lawn Aeration in St. Charles, MO
Fall core aeration and overseeding for St. Charles lawns, from shaded Old Town lots to sunny subdivisions off Highway 94. About twenty minutes from our shop.

Aeration in St. Charles
St. Charles is about twenty minutes from our shop at 2743 Hwy P in O'Fallon. The old river-town neighborhoods have fescue that has fought shade for decades, New Town has small lawns with heavy foot traffic, and the subdivisions south of I-70 have fescue on clay in full sun. All of them benefit from the same September visit: core aeration across the whole lawn, fescue seed into the holes, and starter fertilizer.
On small Frenchtown and New Town lots we use a walk-behind aerator that fits through gates and turns without tearing the turf. On the larger 63303 and 63304 lots we run a wider machine and make two passes where the clay is hardest. Sprinkler heads and dog fences are flagged first, and you get watering instructions before we leave.
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 St. Charles 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.
Shade seed for St. Charles' old neighborhoods
Under the sycamores and oaks near Frontier Park and Blanchette Park, regular fescue struggles no matter how well it is fed. For those lawns we overseed with a blend that leans on shade-tolerant fescue varieties and we cut it tall afterward. In the sunny subdivisions the goal is density: a thick fescue stand in fall is the best crabgrass control you can buy for the following summer.
What aeration costs in St. Charles
Aeration in St. Charles 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.
