How Long Does Weed Control Take To Work & How Long Will It Last?

We know the answers you’re hoping to hear: Weed killer works right away! It lasts forever! Weeds? What weeds?

Timing is Everything: Pre-Emergent Vs. Post-Emergent Weed Control

Pre-emergent weed control targets weed seeds before they sprout. What a great invention, right?

Post-emergent weed killers zap weeds once they already exist.

It’s important to know the difference, and to follow the product instructions when it comes to timing and application. You don’t want to waste your time and money using products that don’t work.

Crabgrass is a great example of the importance of pre-emergent weed killer.

It’s important to apply crabgrass pre-emergent in early spring to target those weed seeds as they germinate and take root in the soil — so they don’t become more seed-producing plants.Crabgrass

How Fast Does Weed Killer Work?

You need a bit of patience here. You’ll usually see weeds curl up and die 7 to 14 days after they’re treated.

But some weeds take longer to disappear than others. Some tough customers really hang in there — some for as long as a month or longer.

Some weeds take multiple applications of weed killer and a couple of months to go away.

One Size Doesn’t Fit All

Before you can start treating the weeds, you need to figure out what you’re up against.

One weed killer doesn’t kill all weeds.

Weeds can be either grassy or broadleaf, with each kind requiring a specific treatment plan. Once you know what type of weed is in your lawn, you can start taking action with a weed killer that targets the type of weed you have. Be sure to follow the label instructions exactly.

How Long Does Weed Control Last?

It depends.

Some weeds are kind of wimpy and one treatment will knock them down.

But tougher weeds like crabgrass keep coming back and need ongoing treatment.

Applying weed killer isn’t a one-time thing. It needs to happen multiple times a year. Different weeds grow at different times throughout the seasons.

That’s why a comprehensive lawn care program is important for real weed control. You don’t have to worry about questions like “how long does weed killer last?” because we stay ahead of them and treat them regularly from spring through fall.

The Best Defense Against Weeds? A Healthy Lawn

Healthy, nourished lawns are less likely to have weed problems, so make sure you keep your yard well maintained.Lawn mowing for healthy lawn

  • Don’t mow too short. Don’t mow more than 1/3 of the grass height at a time.
  • Leave your grass clippings. That will give your grass back some nitrogen and other nutrients — and who doesn’t love free, organic fertilizer?
  • Stick to a proper irrigation schedule. Using system add-ons like a smart controller or rain sensor can ensure you use the exact amount of water your lawn needs, without waste.

Leave It to the Pros

There’s more to efficiently killing weeds than just spraying them with chemicals you found at the store.

You need to know the type of weed you have, what will kill it, how much to spray, and when to apply the treatment.

If all this sounds like waaaay more than you have time for, we get it. That’s where the pros come in, with targeted treatments designed to zap the exact weeds that are driving you crazy.

Weeds can be a symptom of a deeper lawn problem, too, so having a professional diagnose the problem can help make your turf healthy and lush again.
