Types of Weed Killers
Not all herbicides work the same. This section details the differences between the different types so you can make a better decision as to what works for you. If you just want to quickly find out which herbicides work best for the type of grass you have, keep scrolling.
Weed Killer: Liquid vs Granular
Liquid Weed Killer
Liquid weed killers are mixed with water and applied to the lawn with various forms of spray equipment. Liquid herbicides are more effective at penetrating the plant structure as they are sprayed directly onto the plant and do not require the surrounding area to be wet at the time of application. Liquid weed killers can be applied using a variety of sprayers that fit the size of the area that needs to be treated. Smaller areas can be treated with a handheld pump sprayer, while larger areas may require a backpack or vehicle-mounted sprayer. Some users may find it more difficult to mix and spray liquid herbicides as spray equipment is needed.
Following the manufacturer’s instructions while mixing the concentrated liquid weed killer with water is crucial to ensure that you kill the weeds and do not damage your lawn or garden in the process. Diluting the mixture may render the herbicide useless, and concentrating it may burn or shock surrounding plants. Also, you will want to be mindful of overspray into neighboring areas while applying liquid herbicides as a mist of chemical can be carried by even the lightest of winds.
Granular Weed Killer
Granular weed killers are herbicide coated pellets that are spread throughout a lawn to kill a variety of weeds while not harming the grass. Granular herbicides are often applied with a handheld or push spreader allowing for more precise application rates and areas. It may be easier to cover large areas of land with granular products than liquid applications. Granular weed killers are often found in “weed and feed” products that are popular pre-emergent products and generally do not require any mixing or measuring prior to application. Many granular weed killers call for the lawn to be damp before application to allow for the granules to attach to the leaves of the weeds and apply the herbicide to the plant structure. Many users apply a granular weed killer in the morning while the lawn is wet with dew or after a rainstorm to eliminate having to water prior to application.
Choosing the best weed killer for your grass
Best Weed Killer for Centipede Grass
Having a high tolerance for heat and low maintenance requirements, Centipede lawns are popular in the southeastern United States. Low-maintenance doesn’t mean no maintenance, and weeds can still be a recurring problem for centipede lawns, especially in thinner areas of your lawn or in areas where disease or pests have caused problems.
The best Centipede-safe herbicide is Change Up. How good is Change Up? So good that they’ve outlawed it in California and a handful of other states. Expect it to begin affecting weeds in as little as two days. One week after application weeds will be burnt, curled, and obviously in decline. In two weeks, the weeds will be gone. Change Up is also easy to mix in a standard 2-gallon pump-sprayer and for larger lawns, it can be purchased in 2.5 gallon jugs.
Best Weed Killer for Zoysia Grass
A warm-weather but cold-resistant grass, Zoysia is slow to establish but forms a thick, dense lawn once it does. The grass is very popular in America’s midsection for these reasons and it is also relatively easy to maintain.
