How Much Does Lawn Care Cost in St. Louis? (2026 Numbers)

Revised August 13, 2026

Imagine it’s a Saturday in Affton. The grass got away from you during that rainy stretch in May, the mower is making a noise it did not used to make, and the yard across the street has already been cut, edged and blown twice while you were arguing with a pull cord. So you do what everybody does. You get three quotes.

The first company says $40 a cut and can start Thursday. The second says $65, and will not take the mowing unless you also buy the six-application treatment program. The third gives you one flat monthly number for the whole season and never mentions a per-cut price at all. Same yard, same street, three completely different shapes of answer.

That same thing happens in Kirkwood, in Maryland Heights, out past O’Fallon and down in Oakville, and it is not because two of the three are trying to take you. Lawn care in this metro gets priced four different ways — per visit, per month, per application and per square foot — and until you know which one you are holding, the quotes are not comparable at all. Here is what the work actually costs around St. Louis, and what makes one number nearly double another on identical grass.

The short answer

A standard residential mow in St. Louis averages about $69 per visit, with most homeowners paying somewhere between $40 and $118 depending on lot size and access. Plenty of local crews quote in a tighter $35 to $85 band for routine weekly work on an ordinary suburban lot.

Full-service lawn care — mowing plus a fertilization and weed program, billed monthly — commonly runs $100 to $410 a month during the growing season. A season of everything, mowing and treatments and aeration and the fall leaf mess, lands most St. Louis households somewhere around $2,000 to $3,400 a year.

Those are wide ranges on purpose. The rest of this is about which end of them you are on, and why.

What one cut actually costs here

Mowing is priced off square footage first and obstacles second. Around the metro the per-visit tiers look roughly like this:

• One-eighth acre (a typical older city lot in Dogtown or Bevo): about $34 to $46
• One-quarter acre (most of Affton, Ferguson, Overland): about $46 to $63
• Half acre: about $63 to $80
• Three-quarter acre: about $80 to $97
• Full acre (common out in Wildwood or unincorporated west county): about $97 to $114

Then the yard itself moves the number. A flat rectangle with a wide gate is the cheap version of any size. What pushes a quote up is everything that makes a crew get off the mower: a steep front bank, a retaining wall, swing sets, raised beds, a fence line with a gate too narrow for the commercial deck, trees the crew has to trim around by hand, and dogs.

Is $50 for lawn mowing good? In this market, on a quarter-acre lot with normal access, yes — that is squarely inside the fair band and probably a touch under the metro average. On an eighth-acre city lot it is a little rich. On a fenced half acre with three trees and a slope, $50 is a crew that has not walked the property yet and may revise after the first visit.

Per-cut pricing versus a seasonal contract

The St. Louis mowing season runs from roughly late March into November, which pencils out to about 26 to 30 weekly visits in a normal year. That number is the whole ballgame, because it is what turns a per-cut price into an annual price.

At $55 a cut, weekly service across a full season is somewhere near $1,500 before a single bag of fertilizer. That is why so many companies would rather quote you a flat monthly figure: it hides the visit count, smooths their cash flow, and it is genuinely easier for you to budget.

It is also where people get surprised. Ask two questions before you sign anything monthly:

• How many visits does that monthly number assume, and what happens to my bill in a month when you only come twice?
• Is the monthly price for the mowing season only, or is it spread across twelve months including winter?

Every-other-week service looks like the obvious way to cut the bill in half. It usually is not. Skipping a week in May means the crew is removing far more than a third of the blade at once, which shocks the grass and leaves the clippings in rows that have to be bagged or raked. Most companies price biweekly at a premium per visit for exactly that reason, and some will not do it at all during the spring flush.

How much should lawn treatment cost?

Separate from mowing entirely. Fertilization and weed control is quoted per application, and the honest national range is wide: roughly $77 to $395 per application, with big or badly neglected lawns anchoring the top. A typical residential St. Louis lawn on a bundled program is usually toward the bottom of that, in the neighborhood of $50 to $100 per round.

Bought as a program — and almost nobody sells it any other way — four to six applications a year averages about $289. For a quarter-acre property, annual fertilization commonly totals $260 to $510. Add real weed control to it and a full fertilization-plus-weed program lands most homeowners at $400 to $900 a year. Standalone weed treatments run about $49 to $200 each, and a broadcast herbicide visit is typically $50 to $150.

What you should be getting for that, on a St. Louis calendar, looks something like:

• Early spring: pre-emergent for crabgrass, which has to go down before the soil warms, not after you see it
• Late spring: broadleaf control for the clover, henbit and violets that clay soil grows beautifully
• Early summer: a grub preventive
• Midsummer: a light feed and spot treatment, not a heavy nitrogen push
• Early fall: the most important feeding of the year for fescue
• Late fall: the winterizer that builds root reserves

The grub timing is worth knowing, because it is the one application where being a month late means you paid for nothing. Preventive products built on imidacloprid, thiamethoxam or clothianidin reliably knock down 75 to 100 percent of grubs when they go out between June 1 and July 15 and get watered in with a half inch to an inch of irrigation right after. Chlorantraniliprole products can go down as early as April and actually perform better before June. If a company sells you grub control in September, they are selling you a rescue treatment for damage already done, which is a different and less effective product.

Aeration and overseeding: the line item St. Louis actually needs

This is the service most homeowners skip and the one that does the most for a lawn in this region. St. Louis sits on heavy clay. Clay compacts, compaction chokes roots, and choked roots are why the thin patch by the driveway never fills in no matter how much fertilizer goes on it.

Core aeration in the St. Louis area books at an average of about $191, with most jobs falling between $130 and $250. Across St. Louis County the broader range runs roughly $99 to $300. Nationally the math works out near $15 to $18 per 1,000 square feet.

Aeration bundled with overseeding — which is how it should be bought if you have fescue — runs about $160 to $425 for 10,000 square feet, with the grass seed itself driving most of the spread. Turf-type tall fescue seed is cheaper than a premium bluegrass blend, and the difference shows up in the quote.

Two things to check before you pay for it. First, that it is core aeration pulling actual plugs, not a spike machine poking holes, because spiking compacts clay further. Second, that it is scheduled for late summer or fall rather than spring, since a spring aeration on a fescue lawn mostly opens the soil for crabgrass right when the pre-emergent barrier you already paid for gets broken.

Fescue, zoysia, and why your neighbor pays less

St. Louis sits in the transition zone, the strip of the country where it gets too hot for northern grasses and too cold for southern ones. That is why two houses on the same block can have completely different lawn bills.

A tall fescue lawn is the common default here. It stays green longer into the shoulder seasons, which means more cuts, and it thins out every summer, which means it needs overseeding most falls. Fescue is a higher-maintenance, higher-annual-cost lawn.

A zoysia lawn is the other half of the neighborhood. It greens up late, goes tan and dormant from about mid-October until May, grows slowly enough that late-season mowing frequency drops, and it does not get overseeded. Fewer cuts, no annual seed bill. The tradeoff is a lawn that is brown for a long St. Louis winter and a lot harder to repair when something goes wrong in it.

None of that is a reason to switch. It is a reason to make sure the company quoting you knows which grass you have, because a fescue program applied to zoysia is money set on fire, and vice versa.

The August problem

Every year, some time in late July or August, the metro gets a hot dry stretch and unirrigated fescue goes dormant. The lawn browns, growth stops, and the mowing crew has nothing to cut.

This is the single most common billing dispute in local lawn care, and you can head it off with one sentence in the first conversation: what happens to my bill when the grass stops growing? Reasonable answers are that they skip the visit and do not charge, or that they come anyway to blow the drive and trim the edges at a reduced rate. An unreasonable answer is a full mowing charge for running a deck over dormant grass, which stresses it further.

It also matters for treatments. Heavy nitrogen on drought-stressed fescue in August does damage, not good. A program that is honest about the calendar shifts that feeding to September.

Leaves: the fall number nobody budgets for

Older St. Louis neighborhoods came with mature oaks, sycamores and sweetgums, and the bill arrives in November. Yard cleanup in St. Louis averages about $342, with most projects between $190 and $571, and fall cleanups specifically run $180 to $560 because leaf volume here is genuinely heavy.

Priced hourly, leaf work runs about $15 to $45 an hour for blowing, $25 to $50 for raking and $40 to $60 for vacuuming, usually plus $5 to $10 per bag for disposal. That per-bag line is where a cleanup quote quietly doubles under a big pin oak.

The lever you control is the number of passes. One cleanup after everything is down is cheapest. Three passes through October and November keeps the lawn from smothering but costs close to three times as much. Mulching the early drop into the turf with the mower — free, and good for the soil — and paying for one thorough pass at the end is usually the best value in the whole season.

If the leaf problem is really a tree problem, that is a different budget. Our breakdown of what tree removal costs in St. Louis covers where that number lands and what drives it.

What a full year actually adds up to

Put the pieces together for an ordinary quarter-acre St. Louis lawn with weekly mowing:

• Mowing, about 28 visits at roughly $55: near $1,540
• Fertilization and weed program: $400 to $900
• Fall aeration with overseeding: $190 to $425
• One thorough fall cleanup: $190 to $560

That is roughly $2,300 to $3,400 for the year, which is the arithmetic behind those $100-to-$410 monthly full-service quotes. Nothing in there is exotic. It is just that the mowing is two-thirds of the total, and the mowing is the part people negotiate least.

What is the average cost of lawn care per month? For most St. Louis households paying for everything, roughly $190 to $285 a month spread across the mowing season. If you are only buying mowing, cut that to the $150 to $220 range. If you are only buying the treatment program and cutting your own grass, it drops to about $35 to $75 a month.

Making three quotes comparable

Almost every pricing complaint traces back to comparing two numbers that were never measuring the same work. Ask all three companies the same short list:

• Is this per visit or per month, and how many visits does a month include?
• Does mowing include trimming, edging and blowing the hard surfaces, or are those extra?
• Are clippings mulched or bagged, and is there a disposal charge for bagging?
• What is the square footage you measured, and did you measure it or estimate from the street?
• Is the treatment program separate, and can I buy mowing without it?
• What happens in August when growth stops?
• Do you carry liability insurance, and are the people on my property employees or subcontractors?

The measurement question is the sneaky one. A quote built off a satellite estimate of a lot includes the house footprint, the driveway and the patio in the square footage. A crew that walked the yard is quoting the turf you actually have.

Where the money is genuinely negotiable

Some of this bill moves and some of it does not. The parts that move:

• Prepaying the season. Discounts in the range of a free cut or two are common, because it solves a cash flow problem for a small crew.
• Route density. If you and two neighbors sign together, you are worth more per stop and less drive time. This is the biggest lever most people never pull.
• Bagging. Dropping bagging in favor of mulching removes labor and dump fees from every visit.
• Doing the edges yourself. Trimming and blowing is a real share of the crew’s time on site.

The parts that do not move much are fuel, insurance and the applicator’s licensing. If a treatment quote is dramatically under everyone else’s, ask who is holding the license for the application, because in Missouri applying restricted products commercially on someone else’s property is a licensed activity.

Frequently asked questions

What is the average cost of lawn care per month?

In the St. Louis metro, full service — weekly mowing plus a fertilization and weed program — commonly runs $100 to $410 a month during the growing season, with most households near $190 to $285. Mowing alone on a typical quarter-acre lot is closer to $150 to $220 a month at weekly service, and a treatment program by itself averages about $35 to $75 a month spread over the year.

How much should you pay somebody to mow your lawn?

About $69 per visit is the St. Louis average, with the normal range running $40 to $118. By lot size, expect roughly $34 to $46 for an eighth of an acre, $46 to $63 for a quarter acre, $63 to $80 for a half acre and $97 to $114 for a full acre. Slopes, narrow gates, heavy tree cover and bagged clippings all push you toward the top of the band.

Is $50 for lawn mowing good?

For a quarter-acre St. Louis lot with straightforward access, yes — that is a fair price and slightly under the metro average. For a small city lot it is a bit high. For anything approaching a half acre, fenced, sloped or heavily treed, $50 is low enough that you should confirm what is included, because trimming, edging and hauling clippings are often quoted as extras at that price.

How much should lawn treatment cost?

Per application, the range is roughly $77 to $395, though a standard residential lawn on a bundled program usually falls around $50 to $100 per round. As a program, four to six applications a year averages about $289, a quarter-acre property typically totals $260 to $510 for fertilization, and a full fertilization-plus-weed-control program runs $400 to $900 annually.

Are lawn treatment services worth it?

In St. Louis, the value is in timing more than product. Two applications genuinely pay for themselves — the early spring pre-emergent that has to go down before soil temperatures rise, and the fall feeding that builds fescue roots before winter. The grub preventive is worth it only if it goes out between June 1 and mid-July and gets watered in. If a program is selling you six visits but missing those windows, you are buying a schedule rather than results.

Is $100 an hour too much for landscape work?

For one person with a mower and a trimmer, yes, that is high for routine maintenance in this market. For a two-person crew with commercial equipment, insurance and hauling, $100 an hour is normal and often a bargain compared to per-job pricing. Hourly rates make sense for cleanups, bed work and one-off projects. For recurring mowing, insist on a per-visit or per-month price instead, because hourly billing on routine work gives nobody an incentive to move quickly.
