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

Aeration in Hazelwood

Hazelwood is about thirty minutes from our shop at 2743 Hwy P in O'Fallon. Its subdivisions, like Flamingo Park, Pleasant Hollow, and Riverwood, were built in the 1950s through 1970s, and the trees planted then are now sixty feet tall. Fescue under that canopy loses ground every summer, and most Hazelwood front yards have thin, mossy patches where the shade is deepest.

The fix is a September visit: core aeration across the whole lawn, overseeding with a blend weighted toward shade-tolerant fescue, and starter fertilizer. Older zoysia lawns in some subdivisions get aerated in early summer instead, with no overseeding. We flag sprinkler heads and dog fences before the machine starts, and the cores break down on their own in a couple of 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 Hazelwood 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.

Giving shaded fescue a fighting chance

No amount of fertilizer makes fescue grow in deep shade, but the right seed, a tall cut, and open soil get it as close as it gets. We aerate the shaded sections with extra passes, go heavier on seed there, and recommend keeping leaves off the new grass. Hazelwood's free fall leaf collection makes that easier, and we can stage your leaves at the curb for your street's week.

What aeration costs in Hazelwood

Aeration in Hazelwood 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 Hazelwood homeowners

Fall, from early September through mid October. Hazelwood 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 Hazelwood home.
