Lawn treatments in our home city
Our shop is at 2743 Hwy P in O'Fallon, and the lawns we treat here are the ones we drive past every day. Nearly all of them are tall fescue on clay, from the older streets near Fort Zumwalt Park to WingHaven, Hutchings Farm, and the subdivisions along Highway K. Fescue on clay needs feeding in fall more than spring, crabgrass prevention before the forsythia finishes blooming, and broadleaf control through the growing season.
Our 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. Each application is timed to soil temperature rather than a calendar date, and you get a note after every visit with what went down.
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

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.
Weeds we see most in O'Fallon
Dandelion, clover, and henbit show up in every O'Fallon lawn by April, crabgrass fills thin spots by June, and nutsedge pops in the low, wet corners of WingHaven and the newer subdivisions where drainage is poor. Violets are the stubborn one in the older neighborhoods. The spring and summer rounds handle the first group, and nutsedge and violets get their own product on the summer and fall visits. A thick fall overseeding finishes the job by leaving weeds nowhere to start.
What fertilization costs in O'Fallon
Fertilization and weed control in O'Fallon 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.
