Weed Control

Targeted lawn weed control across the Springfield area. Pre-emergent stops crabgrass before it starts and post-emergent clears the weeds already there.

Lawn Weed Control in Springfield

Weeds are opportunists. They don’t beat healthy grass in a fair fight; they sneak into the bare, thin, and compacted spots where the turf has already given up ground. So real weed control is two jobs at once: clear what’s there now, and build a lawn dense enough that new weeds can’t find a foothold. Summit Lawn Care has handled both across the Springfield area since 1985, and as a licensed pesticide applicator we put every product down at label rate.

Pre-Emergent: Stop Crabgrass Before It Starts

Crabgrass is the classic example of why timing beats effort. It comes up from seed every spring, and once it is up, it is tough to kill without beating up the lawn around it. The smart move is to stop it before it germinates.

A pre-emergent application lays a barrier in the top layer of soil in early spring. Crabgrass seed sprouts into that barrier and never makes it to the surface. The catch is the window: it has to go down before the soil warms into the mid-50s, which is why we track soil temperature instead of guessing by the date. Put it down too late and the seed is already past it.

Post-Emergent: Clear What’s Already Growing

For the weeds already in the lawn, dandelions, clover, plantain, ground ivy, we use post-emergent products sprayed onto the actively growing weed. These are most effective when the weed is young and growing, which is why we treat through the season rather than once.

Where weeds are clustered, we spot-treat the patches and leave the rest of the lawn alone. Where they are spread across the whole yard, a broadcast application makes more sense. Matching the method to the problem means less product on your lawn and a better result.

Density Is the Real Weed Control

Here is the part the product label won’t tell you: the best weed control is grass. A thick, well-fed lawn shades the soil so weed seed can’t get the light it needs to sprout, and it leaves no bare ground for weeds to claim.

That is why we never sell weed control as a standalone fix for a thin lawn. We pair it with a fertilization program to build density, with aeration and overseeding to close bare spots and relieve the compaction weeds love, and with a proper mowing height that shades out crabgrass on its own. We stand behind the program and adjust it as the lawn fills in.

Serving the Whole Springfield Area

We treat lawns in Springfield, Riverton, Lakeside, and Cedar Grove, plus Maplewood and Fairview. Most homeowners bundle weed control into our annual lawn program so the timing is handled for them.

Frequently Asked Questions

What is the difference between pre-emergent and post-emergent weed control?
Pre-emergent stops weed seeds from growing, and post-emergent kills weeds that are already up. Pre-emergent lays a barrier in the soil in early spring that crabgrass seed can't push through, while post-emergent is sprayed on actively growing weeds like dandelions and clover to take them out. A good program uses both, timed to the season.
When should crabgrass pre-emergent go down?
In early spring, before the soil warms enough for crabgrass seed to germinate, which in our area is usually when the soil hits the mid-50s and the forsythia blooms. Miss that window and the seed sprouts past the barrier, so timing is everything. We watch soil temperatures rather than the calendar to put it down at the right moment.
Why does my lawn keep getting weeds?
Weeds move into the gaps a thin lawn leaves open, so chronic weeds usually mean a turf problem underneath. Bare spots, compacted soil, mowing too short, and underfeeding all hand weeds an opening. We clear the weeds you have, then work on the density that keeps new ones from finding room, which is the only lasting fix.
Is weed control safe around kids and pets?
Yes, when it is applied correctly by a licensed applicator following the label, which is how we treat every lawn. We use targeted products at label rate and ask that people and pets stay off the treated area until it has dried, usually a couple of hours. We will tell you the re-entry time for each visit before we leave.
Can you get rid of weeds without treating the whole lawn?
Often, yes. When weeds are clustered in a few areas rather than spread across the lawn, we spot-treat just those patches instead of blanketing everything, which uses less product and leaves the healthy turf alone. Widespread weeds across the whole lawn make a broadcast application the better call. We match the method to what the lawn actually has.
