Brought to America in the 1500s by the Spanish, Bermuda grass is a cold-weather tolerant, warm-season grass. Bermuda grass will stay green all year long in warm tropical climates. In areas where temperatures drop below 60 degrees F. (15 C.), the grass will turn brown as it has gone dormant.

While there are a lot of positives to having drought-tolerant grass like Bermuda surrounding your home, it is prone to common weeds that can quickly become a problem like many other lawn varieties.

When choosing a Bermuda grass weed killer, it’s essential to remember that you need to select a blend that won’t harm or kill the grass. To do this, you’ll want to make sure you choose a selective weed killer.

Selective weed killers will find and destroy the weeds without harming your lawn. A nonselective weed killer does precisely what it sounds like. It’s going to destroy anything it comes in contact with.

To help you battle the weeds growing in your Bermuda grass, I’ve tested some of the top herbicides to help you choose the right products to keep your grass green and free of pesky weeds.

In a rush? These are the ones I recommend. But keep reading if you want more info on each.

Image Kills Nuts Sudge Concentrate

If you have ever had Nutsedge invade your lawn, you know how frustrating it can be. Customers generally rave about this product’s ability to eliminate Nutsedge efficiently. While you can apply to your entire lawn or use it in spots, I recommend applying it in spots to avoid the potential of applying too much at one time.

Pros

  • This post-emergent herbicide comes in either a 24oz concentrate bottle for homeowners with more square feet to cover or a convenient premixed 32oz formula that attaches to your hose.
  • Kills most Nutsedge in less than 48 hours

Cons

  • While this product will eliminate more than just Nutsedge, there are many weeds it will not affect, making this product a poor choice if you have a variety of unidentified weeds in your grass.

Selecting a Pre-emergent, Post-emergent….or Both

best post emergent weed killer

Technically, all herbicide weed killers are, in fact, post-emergent. This means that active ingredients in either a granular or liquid formula kill unwanted weeds vegetation after they have emerged from the weed seeds.

That said, pre-emergent weed killers will create a barrier at the soil level that prevents the seeds of unwanted weeds from ever sprouting. Post-emergent weed killers are applied after weeds have taken root in your lawn.

  • If you have a small patch of weeds or larger weeds growing in an otherwise healthy lawn, you may consider spraying the patch of weeds with a selective herbicide instead of treating the entire lawn. Not only will this save you time, but it also allows you to preserve unused portions of the product to be applied if more weeds pop up later.
  • One thing to consider when choosing a pre-or post-emergent is that most pre-emergent killers will not only prevent unwanted weeds from sprouting but also keep any new Bermuda grass seed from sprouting as well. You don’t want to apply a pre-emergent until your Bermuda grass has taken root.

Tips for Applying Bermuda Grass Weed Killers

herbicide that kills everything but bermuda grass
  • Be proactive. As the first sign of seeing weeds on your lawn, try to spray it with a selective lawn weed killer. Catching the weed growth early in the growing cycle allows you to use a selective weed killer to kill whatever may be lurking in your grass. Using a selective killer to treat broadleaf weeds and other unwanted plants minimizes the damage you can do to your lawn, keeps the unwanted weeds from spreading, and will cut down the applications you need to make-saving you money.
  • Read the product label! All weed killers are not the same. Make sure you use a weed killer where the label says it is safe for Bermuda grass. You will also want to make sure you are applying it correctly, or if you ha e purchased a concentrate, you are mixing it with water correctly.
  • Take time applying liquid or granular pre-emergent herbicides to your soil and lawn. You do not want to accidentally spray or spread the formula that is intended for your lawn and lawn soil to your neighboring flower gardens. The active ingredients in these formulas will almost certainly kill any of these types of plants it comes into contact with.
  • The square feet that a herbicide will cover varies from product to product. For some, this can be a significant factor in choosing a product. Reading the product description is essential to ensure your lawn has enough herbicide.
  • Some products need to be applied when there is no rain in the extended forecast, while others require some moisture to kickstart the herbicide into action. Make sure you read the product label for application instructions for the best results.

Summary

All the products I reviewed will kill the weeds in your Bermuda lawn if applied correctly. Southern Ag weed Killer for Bermuda grass stood out to use as the top choice because of its ability to kill weeds quickly, after only one application.

Our best price pick, BioAdvanced Bermudagrass control for the lawn, will eradicate broadleaf weeds while not harming your lawn and can be purchased relatively cheaply.

Supplementing your fertilizer routine with a pre-or post-emergent herbicide to eliminate lawn weeds will help you achieve the lush, green Bermuda grass lawn your neighbors will envy.
