Lawn treatments in St. Peters

St. Peters is about fifteen minutes from our shop at 2743 Hwy P in O'Fallon. The 1970s neighborhoods like Country Hill and Spencer Creek have fescue thinned by mature shade, and shade lawns need lighter feeding and more attention to moss and broadleaf weeds. The 1990s and 2000s subdivisions have full-sun fescue on clay that needs crabgrass prevention and summer stress care more than anything.

Our five-round program covers both: crabgrass pre-emergent with the early spring feeding, broadleaf control in late spring, a summer round with spot treatment, an early fall feeding, and a late fall winterizer. We measure your turf for a per-application price and adjust the summer and fall rounds for shade or sun. Each visit leaves a flag and a note.

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. Peters

From the first call to a finished yard, here is what to expect.

Tell us about your yard

Call (636) 293-9306 or send the form with your St. Peters address and what you need. We reply the same business day.

We measure and quote the lawn

The price is based on your St. Peters 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.

Fescue and zoysia on the same street

Older St. Peters lawns are often zoysia, which wants a completely different program: feeding only from May through August and nothing in spring or fall, when it is dormant. If your yard has a zoysia front and a fescue back, we run both schedules and keep them separate. Nutsedge in the low spots near Spencer Creek and violets under the big trees get their own products on the summer and fall rounds.

What fertilization costs in St. Peters

Fertilization and weed control in St. Peters 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 St. Peters homeowners

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