Lawn treatments in Florissant

Florissant is about thirty to thirty-five minutes from our shop at 2743 Hwy P in O'Fallon. Lawns around Koch Park and Old Town and in Paddock Hills and Sacre Coeur have decades of oak and sycamore shade, while the subdivisions toward New Halls Ferry are sunnier and fight crabgrass instead of moss. Zoysia is common in some neighborhoods and gets its own summer-only schedule.

Fescue lawns get 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. We measure the turf for a per-application price, lighten the spring feeding on shaded lawns, and leave a flag and a note after every visit.

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 Florissant 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.

Matching the program to the shade

Under Florissant's big trees the fall rounds carry the program, building roots when the canopy opens up and the grass gets light. Violets and wild strawberry are the usual weeds there. In the sunny subdivisions the spring pre-emergent is the round that matters most, and it has to be down by early April. Pairing either program with September aeration and overseeding is what turns a thin lawn thick within a couple of seasons.

What fertilization costs in Florissant

Fertilization and weed control in Florissant 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 Florissant homeowners

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