Lawn treatments on Weldon Spring lots

Weldon Spring is about twenty to twenty-five minutes from our shop at 2743 Hwy P in O'Fallon. Its one- to three-acre lots and Whitmoor's golf-course homes have more turf than any other city we serve, much of it under mature oak and hickory. A lawn that size is priced by measured square footage, and a shaded lawn gets a lighter feeding schedule than a sunny one, so the first step is a measurement and a look at the canopy.

The 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. On shaded sections we reduce nitrogen and focus on broadleaf and moss control. Each visit leaves a flag and a note, and you do not need to be home.

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 Weldon Spring

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 Weldon Spring 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.

Feeding fescue under hardwood canopy

Fescue in deep shade cannot use heavy spring nitrogen; it just grows weak and gets disease. The fall rounds do the real work on a Weldon Spring lawn, building roots while the trees are losing leaves and the grass finally gets light. Violets and wild strawberry are the usual weeds under the trees, and they get their own product on the fall round. Whitmoor homes have HOA standards for lawn condition, and a clean program keeps yards inside them.

What fertilization costs in Weldon Spring

Fertilization and weed control in Weldon Spring 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 Weldon Spring homeowners

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