Lawn treatments in Cottleville

Cottleville is about fifteen minutes from our shop at 2743 Hwy P in O'Fallon. Lawns in Cottleville Trails, Prairie Bluff, Ashford Knoll, and the other subdivisions off Highway N are tall fescue on clay, now partly shaded by trees that have grown up over twenty years. That mix needs crabgrass prevention in the sunny front, lighter feeding under the trees, and broadleaf control everywhere.

Our five-round program handles it: 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. The price is per application, based on your lawn's square footage, and every visit leaves a flag and a note on what was applied and when the lawn is ready to use.

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 Cottleville 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.

Keeping Cottleville lawns inside HOA lines

Many Cottleville subdivisions keep standards for how yards look, and a lawn full of dandelions in April is the first thing a board notices. The early spring and late spring rounds clear dandelion, clover, and henbit before they go to seed, and the summer round catches what breaks through. Nutsedge in the wet low spots along the Dardenne Creek corridor and violets under the maturing trees get their own products on the summer and fall rounds.

What fertilization costs in Cottleville

Fertilization and weed control in Cottleville 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 Cottleville homeowners

Before soil temperatures hold around 55 degrees, which in Cottleville 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. Charles 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 Cottleville and we coordinate both.
