We see the same thing every spring in McKinney. A lawn looks fine one week, then weeds pop up like they paid rent. Most of that trouble starts months earlier, which is why many homeowners turn to lawn service in McKinney for pre-emergent care that stops weeds before you ever see them. When it’s done right, it saves time, money, and a lot of frustration.
At Stonebridge Lawn and Garden, this is something we do every season. We just finished pre-emergent applications for several homes near Eldorado and Ridge Road, and the timing could not have been better. North Texas weather moves fast, so the plan matters.
Below are the best practices we follow and why they work in McKinney, TX.
What does pre-emergent really do for lawns in McKinney?
Pre-emergent does not kill weeds you already see. It stops weed seeds from sprouting in the first place. That makes it perfect for crabgrass, foxtail, and other warm-season weeds we deal with here.
Why McKinney lawns need a local plan
Our soil is heavy clay. Water sits longer, and products behave differently than they do in sandy soil. Add fast spring warm-ups, and timing becomes everything.
Weed seeds wake up early. Once soil temperatures hit the mid-50s, seeds start growing even if the air still feels cool.
Clay soil holds moisture. That helps pre-emergent last, but only if it’s applied evenly.
When should pre-emergent be applied in McKinney, TX?
This is the question we hear most.
For spring weeds, we aim for late February to early March. For fall weeds, September is the usual window. Waiting too long means the weeds already won.
Watching soil, not the calendar
We don’t guess. We track soil temps and weather swings. We just adjusted a schedule last year after a warm February, and it kept crabgrass out of a lawn near Adriatica all summer.
Early timing blocks growth. Pre-emergent forms a barrier before weeds can break through.
How should pre-emergent be applied for even coverage?
Coverage matters more than most people think. Missed spots turn into weed patches.
Professional spread patterns make a difference.
We apply in two crossing passes. That helps avoid light streaks and heavy lines.
Even spread prevents gaps. Gaps are where weeds sneak through first.
Correct rate protects turf. Too much stress grass roots, especially in the heat.
Should lawns be watered after the pre-emergent is applied?
Pre-emergent needs water to move into the soil. Without it, the product just sits on top.
Getting water right in McKinney
We usually water within 24 hours unless rain is coming. A light, steady soak works best.
Water activates the barrier. It locks the product into the top layer of soil.
Short cycles reduce runoff. This helps with clay soil and city watering rules.
What mistakes do homeowners make with pre-emergent?
We see the same issues every year.
Common problems we fix
Applying too late lets weeds win. Once weeds sprout, pre-emergent can’t stop them.
Skipping fall treatments invites winter weeds. Poa annua loves missed fall apps.
Mowing too low weakens grass. Thin turf leaves space for weeds.
We recently helped a homeowner near Craig Ranch who skipped fall treatment. By spring, weeds were everywhere. A full plan got it back on track, but prevention would have been easier.
How does pre-emergent fit into a full lawn plan?
Pre-emergent works best as part of a full care routine. It pairs well with proper mowing, feeding, and smart watering.
Building strong turf
Healthy grass crowds out weeds. Thick turf leaves no room for seeds.
Seasonal timing keeps lawns steady. Each step supports the next.
This is how we handle lawns across McKinney, not just one visit at a time.
Frequently Asked Questions About Lawn Service
Can pre-emergent stop weeds you already see?
No. It only stops seeds before they sprout. Existing weeds need a different approach.
Is pre-emergent safe for established lawns?
Yes. When applied at the right rate, it protects grass while blocking weeds.
Do I need pre-emergent every year?
Yes. Weed seeds arrive each season, so yearly applications help keep lawns clean.
Want weeds stopped before they start?
Pre-emergent is one of the smartest moves for McKinney lawns, but only when timing, coverage, and watering line up. We apply it with local weather, soil, and grass types in mind because that’s what works here.
