Fertilization & Weed Control in St. Charles, MO
A five-round fertilization and weed control program for St. Charles lawns, from shaded Old Town lots to full-sun subdivisions off Highway 94. About twenty minutes from our shop.

Lawn treatments in St. Charles
St. Charles is about twenty minutes from our shop at 2743 Hwy P in O'Fallon. The lawns near Frontier Park and in Frenchtown sit in deep shade and fight moss and violets. New Town's small lawns take heavy foot traffic. The subdivisions south of I-70 are sunny fescue on clay with crabgrass and clover pressure. One program with the right adjustments handles all three.
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 feeding on shaded lawns, and leave a flag and a note after every visit so you know 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

How fertilization & weed control works in St. Charles
From the first call to a finished yard, here is what to expect.

We measure and quote the lawn
The price is based on your St. Charles 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.
Pre-emergent timing in St. Charles
Crabgrass germinates once daily highs settle around seventy degrees, which in St. Charles usually means late March to early April, about when the forsythia along the older streets blooms. The pre-emergent has to be down before that, so the first round goes out early and we do not wait for a nice-looking lawn to start. A thick fall overseeding makes the following spring's pre-emergent far more effective by leaving less open soil.
What fertilization costs in St. Charles
Fertilization and weed control in St. Charles 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.
