Thick, striped fescue lawn after aeration and overseeding in Florissant, Missouri

Aeration in Florissant

Florissant is about thirty to thirty-five minutes from our shop at 2743 Hwy P in O'Fallon. The lawns around Koch Park and Old Town and in Paddock Hills and Sacre Coeur have had decades to compact and decades of oak and sycamore shade to thin the fescue. The subdivisions toward New Halls Ferry are sunnier and thin from heat instead. Both come back with a September aeration and overseeding.

We core aerate the whole lawn, overseed with a turf-type tall fescue blend matched to the shade, and apply starter fertilizer in one visit. Zoysia lawns, which are common in some Florissant subdivisions, get aerated in early summer instead. Sprinkler heads and dog fences are flagged first, and you get watering instructions for the first few weeks.

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 Florissant 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.

Timing around Florissant's leaf season

The one thing that undoes a fall overseeding is a wet mat of leaves on the new grass, and Florissant's canopy drops for six weeks. We aerate in September or early October and recommend an early leaf cleanup in November so the seedlings get light through their first fall. Everything we clear is hauled away, since the city does not allow leaves on the sidewalk or street.

What aeration costs in Florissant

Aeration in Florissant 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 Florissant homeowners

Fall, from early September through mid October. Florissant 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. Louis 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 Florissant home.
