Lawn Fertilization & Weed Control in Waco, TX

A seasonal feeding and weed-control program built around how warm-season grass actually grows on Blackland Prairie clay — right products, right timing, no guesswork. Serving Waco, Woodway, Hewitt and Robinson since 2004.

A Program Built for Central Texas Grass

Fertilizer bought off a shelf and spread whenever is how a lot of Waco lawns end up yellow in July or full of grassburs by August. Warm-season grasses — Bermuda, St. Augustine, Zoysia — only use nutrients when they're actively growing, and our alkaline clay soil changes what they can absorb. M&M Lawn Service runs a scheduled program tied to soil temperature and grass growth, not the calendar alone, so each application lands when the lawn can actually use it.

What the Program Covers

  • Seasonal fertilization — 3–4 feedings from green-up through early fall, matched to your grass type
  • Pre-emergent weed control — spring and fall barrier applications to stop weeds before they sprout
  • Post-emergent weed control — spot and blanket treatment of weeds already up, selective so it won't hurt the grass
  • Iron treatments — for the deep green color that alkaline soil otherwise robs from St. Augustine and Bermuda
  • Grub & chinch bug treatment — timed to the insect's life cycle, not just when damage shows
  • Fire ant control — mound treatment and broadcast bait options
  • Disease ID — spotting brown patch, large patch, take-all root rot and gray leaf spot early and adjusting watering and feeding before it spreads

The Waco Fertilization Calendar

  • Feb–early March: spring pre-emergent when soil hits the mid-50s — ahead of crabgrass and grassburs (sandburs)
  • March–April: light starter feeding as the grass greens up; post-emergent on winter weeds still hanging on
  • May–June: main feeding as growth peaks; iron for color
  • July–August: slow-release summer feeding only on irrigated lawns; grub and chinch bug watch
  • September–early October: fall pre-emergent for Poa annua and henbit; potassium-focused feeding to harden turf for winter
  • After first frost: nothing — dormant grass can't use fertilizer, and feeding it just feeds the weeds

Pre-emergent timing is the whole game. The spring barrier has to be down and watered in before soil temperatures hit the mid-50s. In a warm February that can be the third week of the month. A week or two late and crabgrass and grassburs are already germinating — then it's a season of post-emergent catch-up.

Why Waco Lawns Need This

Alkaline clay ties up nutrients

Blackland Prairie soil runs high pH. Iron and some micronutrients are present but "locked" — the grass goes yellow-green no matter how much nitrogen you throw at it. Targeted iron fixes the color; excess nitrogen just makes it grow faster and weaker.

Heat and drought stress

A properly fed root system goes deeper and rides out August and water restrictions far better than a lawn that's been starved or over-pushed with quick-release nitrogen.

Weed pressure is relentless

Grassburs, crabgrass, nutsedge, dallisgrass, clover, henbit, dandelion — Central Texas grows all of them well. A thick, fed lawn plus timed pre-emergent is the only thing that keeps ahead of it.

Chinch bugs and grubs

Chinch bugs can take out a sunny St. Augustine lawn in weeks of peak summer. Grubs hollow out roots in late summer. Both are predictable enough to treat on schedule.

Grass-Specific Feeding

  • Bermuda: the heaviest feeder — responds to regular nitrogen through the growing season, wants full sun, recovers fast from stress
  • St. Augustine: moderate nitrogen, and iron for color; do not overfeed — lush St. Augustine is more prone to brown patch and chinch bugs
  • Zoysia: light, steady feeding; slow to respond, easy to overdo
  • Buffalograss: minimal — it's a native adapted to lean soil, and heavy feeding invites weeds

Common Waco Weeds We Treat

  • Warm-season: crabgrass, grassburs / sandburs, dallisgrass, nutsedge (nutgrass), spurge, Virginia buttonweed
  • Cool-season: annual bluegrass (Poa annua), henbit, chickweed, clover, dandelion, thistle, rescuegrass

What Affects Your Price

  • Turf square footage treated
  • Full program vs. individual applications — a season program per visit costs less than one-off treatments
  • Add-on treatments — grub, chinch bug, fire ant and disease work priced separately when needed
  • Starting condition — a weed-heavy lawn needs extra post-emergent visits in year one

Fertilization & Weed Control FAQ

When does pre-emergent go down in Waco?

Twice a year — spring when soil hits the mid-50s (mid-Feb to early March, before crabgrass and grassburs) and fall in September–October for Poa annua and henbit. Miss the window and you're pulling weeds all season.

How many feedings a year?

Three to four between April and September: starter at green-up, main feeding in late spring, an optional slow-release summer feeding on watered lawns, and a fall potassium feeding. Nothing on dormant winter grass.

Why is my St. Augustine yellow after fertilizing?

Alkaline soil locks up iron. The fix is usually an iron treatment, not more nitrogen. It can also be chinch bugs in a hot dry spot or take-all root rot in a wet one — we check first.

Do you treat chinch bugs and grubs?

Yes. Chinch bugs hit sunny St. Augustine June–September; grubs damage roots in late summer. Both are treatable, and matching the timing to the insect's life cycle matters as much as the product.

Is it safe for kids and pets?

Stay off until liquids dry (1–2 hours) and water in granular products before reuse. We label-follow every product and tell you the re-entry time for that day's application.

Can it fix a lawn that's mostly weeds?

Partly — a program thickens thin turf and crowds out weeds over a season or two. But if it's more than about half weeds or bare dirt, or the thin spots are from shade or drainage, fertilizer alone won't do it and we'll say so.
