Lawn treatments in Chesterfield

Chesterfield is about thirty minutes from our shop at 2743 Hwy P in O'Fallon. The upland subdivisions off Clarkson and Olive have big fescue lawns under forty-year-old oaks, and the Valley sits on rich floodplain soil that stays wet in spring. Shaded lawns need lighter spring feeding and more attention to moss and violets. Valley lawns need nutsedge control and care about application timing around rain.

The program runs five rounds: early spring fertilizer with crabgrass pre-emergent, late spring feeding with broadleaf control, a summer treatment with spot-spraying, early fall fertilizer, and a late fall winterizer. Larger lots are priced by measured turf area. Every visit leaves a flag and a note, and you do not need to be home.

What the program includes

Early spring fertilizer with crabgrass pre-emergent

Late spring feeding with broadleaf weed control for dandelions, clover, henbit, and plantain

Summer treatment timed for heat, with spot-spraying of weeds that break through

Early fall fertilizer to rebuild roots after summer stress

Late fall winterizer so the lawn greens up early next spring

A note after each visit on what was applied and what to watch for

We measure and quote the lawn

The price is based on your Chesterfield lawn's square footage. You get a per-application price and the full season schedule up front.

Applications on schedule

Each round goes down in its window, timed to soil temperature rather than a calendar date. You do not need to be home.

A thicker lawn each year

Dense turf crowds out weeds on its own. By the second season most lawns need far less spot treatment.

Feeding fescue under Chesterfield's oaks

In Village Green, Fairmount, and Claymont the lawn under the canopy cannot use heavy spring nitrogen, so the fall rounds carry the program, building roots when the trees drop their leaves and the grass finally gets light. Violets and wild strawberry under the trees get their own product on the fall round. Pairing the program with September aeration and a shade-tolerant overseeding is what keeps those lawns from going bare.

What fertilization costs in Chesterfield

Fertilization and weed control in Chesterfield is priced per application, quoted for free from a measurement of your turf. The price depends on:

Lawn square footage. Product is applied by area, so a larger lawn costs more per round.

Number of rounds. The standard program is five applications. Lawns coming off a rough year sometimes add a sixth.

Current condition. A lawn that is mostly weeds needs heavier broadleaf treatment the first season.

Add-ons. Grub control, fall aeration, overseeding, and lime for acidic soil can be added to the program.

Fertilization & Weed Control questions from Chesterfield homeowners

Before soil temperatures hold around 55 degrees, which in Chesterfield is usually late March to early April, about when forsythia blooms. Miss that window and the pre-emergent cannot stop seed that has already sprouted.
Five is the standard for tall fescue in St. Louis County: early spring, late spring, summer, early fall, and late fall. Zoysia lawns get a different schedule weighted toward summer.
Once the application has dried, usually within an hour or two, the lawn can be used normally. We leave a flag and a note after each visit so you know when it went down.
Yes. Both need a different product than ordinary broadleaf killer, and we treat them on the summer and fall rounds. Violets take a couple of seasons to fully knock back.
Yes. Fertilizer does its best work on a lawn that is mowed high and watered deeply about once a week in summer. Pair the program with our mowing in Chesterfield and we coordinate both.
