Idaho Falls Weed Control: How to Prevent & Treat Common Weeds in Your Lawn

Nothing can wreck your blissful backyard vibe like weeds.

Crabgrass. Dandelions. White clover.

Time for some basic Idaho falls weed control.

Let’s get to it. Weeds spread fast.

How to Prevent Weeds with Proper Maintenance

The best way to beat these weeds is to establish healthy turf, including proper fertilizing, watering, and mowing.

Follow these tips for Idaho Falls weed control:

  • Don’t cut your grass too short. We know, it’s tempting to mow short so you don’t have to mow as often. But if you cut your grass too short, it can suffer from shock — leaving it prone to weeds and making it less capable of dealing with drought stress. Don’t mow more than 1/3 of the grass’s height at a time.
  • When mowing, mulch the grass clippings and leave them in your yard. That will give your grass back some nitrogen and other nutrients — and who doesn’t love free, organic fertilizer?
  • Stay on top of fertilizer treatments. They keep your lawn strong, healthy, and better able to resist weeds. And don’t forget that important fall fertilizer application. It gives your lawn’s roots nutrients to grow nice and deep, with some left over for a healthy start the next spring.
  • Stick to an irrigation schedule to keep your lawn healthy, especially during warmer months. Using system add-ons like a smart controller or rain sensor can ensure you use the exact amount of water your lawn needs, no more and no less.

How to Prevent Weeds with Timing of Weed Killer

Beyond maintenance, the best way to have a weed-free lawn is to prevent them from growing in the first place.

The trick to keeping weeds from popping up throughout your lawn is well-timed treatments. By applying pre-emergent herbicides during the winter or early spring (before growth begins), you can prevent weeds from growing.

It’s important to apply the pre-emergent herbicides early enough because if you wait too late, they won’t be effective.

How to Get Rid of Weeds Once They Show Up

Once the weeds have broken ground, you can use post-emergent herbicides to control them.

But there’s a trick to this — you need to know what you’re up against.

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 take action with a weed killer that targets the type of weed you have. Be sure to follow the label instructions exactly.

If I Did Everything Right, Why Do I Still Have Weeds in My Lawn?

It doesn’t seem fair, does it? You dutifully follow the “how to prevent weeds” rules. But despite your best efforts, or the efforts of your lawn care service, weeds happen.


  • Weeds are shifty. They love to lurk in your lawn as seeds, sometimes for years, just waiting for the right conditions to come along.
  • Some resistant perennial weeds can take multiple herbicide applications over several seasons to control — even with the best weed control tactics.
  • Seeds, seeds, seeds. If your neighbor didn’t tend to his weeds, the seeds from his are happily blowing into your yard, and settling in to sprout. Birds drop them in your yard. They nestle in your dog’s fur when you’re out for a walk. You even track them into your yard on your shoes.
  • No herbicide kills every weed. No single herbicide, weeding technique, or lawn care strategy works against all weeds. They come in too many varieties. Some succumb quickly to a treatment. Others hang on. And on. And on.
