We’ve blogged extensively about centipede grass. With a beautiful green color, heat tolerance, and a need for sunlight, it is easy to see why it is a popular choice for many homeowners. If you have chosen centipede grass for your lawn, there are a few steps that you can take to make your neighbors green with envy: mowing, fertilizing, and weed maintenance.
Selecting the best weed killer for centipede grass will allow you to take your lawn to the next level. Below, we will look at several options that you can use throughout the year on your centipede grass.
Best Pre-emergent Weed Killer for Centipede
In the colder months of the year, your centipede will grow very slowly and require very little maintenance. Therefore, the best weed killer for centipede during winter will not be the same thing you use during the summer.
During winter, you should apply a pre-emergent herbicide to your lawn. This is because it will help to prevent weeds from ever taking root in your yard. Getting a head-start on weeds in the winter can save you a ton of hassle in the summer.
Finally, apply a pure pre-emergent to your centipede grass and not a weed and feed. This is because you shouldn’t fertilize centipede in the winter when it isn’t growing.
Best Granular Pre-emergent Weed Killer for Centipede
Anderson’s granular product is a superior herbicide that will stop 35+ of the most common weeds from taking root in your yard. Barricade pre-emergent herbicide should be applied in March or April with a push or hand spreader. It has an expected life of 60-90 days.
Prodiamine, the active ingredient in Barricade, is safe for use in your centipede lawn if applied to the manufacturer’s specifications. Favored by many golf course superintendents and turfgrass managers, it is regarded as one of the best weed killers for centipede grass.
Best Liquid Pre-emergent Weed Killer for Centipede
Tenacity is a liquid broadleaf weed herbicide that is safe for centipede. Tanacity requires mixing with water before you spray it on your lawn. It makes contact with the soil in your yard and waits for pesky weeds to begin growing. When they do, they are stopped dead in their tracks. The weed killer lasts 45 – 60 days. When applied at the appropriate time, it will last until the beginning of the heavy growing season.
Mesotrione is the active ingredient in Tenacity and is an excellent weed killer. It is important to note that some more specialized equipment may be required when applying a liquid herbicide to your yard. This may include a backpack or ATV sprayer, gloves, and a mask. Always follow the manufacturer’s application rates and safety instructions when applying an herbicide.
Best Post-emergent Weed Killer for Centipede
After the pre-emergent herbicide has done its job and has begun to break down, your lawn will have entered into its growing season. Once in the warmer months and growing season, it is time to apply a post-emergent herbicide. Most pre-emergents only hold back weeds 45-60 days. Therefore, a post-emergent is needed to kill any late bloomers that pop through.
Unlike a pre-emergent herbicide, post-emergent products kill weeds after they have begun to grow. You may need to apply a post-emergent product several times in the warmer months to keep weeds at bay.
Best Granular Post-emergent Herbicide for Centipede
Gordon’s Trimec herbicide is one of the best weed killers for centipede grass. This is because of its ability to kill 75+ broadleaf weeds without harming turf grasses. With such a broad range, Gordon’s product is one of the most versatile turfgrass herbicides on the market.
To use, mix with water and apply to the yard with a sprayer. Results should be seen in a few days.
Trimec is potent! Therefore, don’t use more than twice a year. Also, don’t reapply sooner than 45 days.
