12 best grass killers

Grass killers, often referred to as weed killers or herbicides, are products used to control or eliminate unwanted grass and weeds in gardens, lawns, and other outdoor areas. These products are essential tools for maintaining a healthy and weed-free garden or landscape.Here are some key points to consider when it comes to grass killers:

  1. Types of Grass Killers:

    • Selective Herbicides: These target specific types of plants, such as broadleaf weeds, without harming desirable grasses. They are commonly used in lawns to eliminate weeds while preserving the grass.
    • Non-Selective Herbicides: These kill a wide range of plants, both grasses and broadleaf weeds. They are often used to clear large areas of vegetation, like driveways or garden beds, before replanting.
  2. Mode of Action:

    • Contact Herbicides: These kill plants on contact, primarily affecting the parts of the plant they come into direct contact with, such as leaves.
    • Systemic Herbicides: These are absorbed by the plant and move throughout its system, ultimately killing the entire plant, including the roots.
  3. Application Methods:

    • Spray: Most grass killers come in liquid form and are applied using a sprayer. This method is suitable for both spot treatments and larger areas.
    • Granules: Some herbicides are available in granular form, which can be spread directly onto the target area.
  4. Safety Precautions:

    • Always follow the manufacturer's instructions and safety guidelines when using grass killers.
    • Wear appropriate protective gear, such as gloves and eye protection.
    • Keep children and pets away from treated areas until it's safe.
    • Properly store herbicides in a secure location away from food and drink.
  5. Timing:

    • Timing is crucial when applying grass killers. Some herbicides are more effective when applied during specific seasons or when weeds are at a certain stage of growth.
  6. Residual Effects:

    • Some grass killers have residual effects, which means they can remain active in the soil for an extended period. Be mindful of this when planning future plantings in treated areas.
  7. Environmental Impact:

    • Consider the environmental impact of the herbicide you choose. Some are less harmful to the environment than others, so choose one that aligns with your eco-friendly gardening goals.
  8. Brand and Product Selection:

    • There are various grass killer brands and products on the market. It's important to select a product that suits your specific needs and the types of weeds or grasses you want to eliminate.
  9. Weed Prevention:

    • While grass killers are effective at eliminating existing weeds, it's also essential to implement weed prevention strategies, such as proper lawn care, mulching, and regular maintenance, to minimize weed growth in the future.

Remember that effective weed control often involves a combination of strategies, including grass killers, to achieve the desired results. Integrated weed management practices can help you maintain a healthy and weed-free garden or lawn while minimizing the environmental impact of herbicide use.

User questions & answers

Question: Can it be used on new fescue grass? How long until after you seed can it be used
Answer: It can be used on fescue. It should be mowed several times before using any herbicide and never apply above temps of 90 degrees. Any new grass is rather weak, until it has a good root system. The longer you can wait, the better it will be for the new grass.
Question: IS IT SAFE ON MARATHON AND TALL FESCUES GRASS
Answer: I live in Southern California and use this on my Marathon to kill everything else in the grass (particularly Bermuda and clovers). It works great. I really recommend using a stronger concentration than recommended, about 2x. Be sure to turn off your sprinklers for 72 hours after spraying and don't spray on an overly hot day. I spray in the Spring and Summer. It isn't really necessary except spot treatment in the Fall and Winter. Good luck!
Question: does this product have an expiration date ? How long can you store the product and will remain effective
Answer: I took a look at the two bottles that I have. They do not have expiration dates on them. They do have lot numbers. Generally, herbicides and insecticides have a very long shelf life, but keep them sealed up so they do not change the dilution properties from evaporation.
Question: Will this kill nutsedge
Answer: I had a field 150’ x 100’ of random weeds and lots of burr clover with spike balls in my back yard. This killed all of the weeds - every type and left the few small patches if real grass still alive. No idea about nutsedge but I won’t purchase any other product. This was highly recommended from a gardener and it killed everything but the grass, and I had some big ugly weeds with thorns and the spike balls.

User questions & answers

Question: Does this product leave a disapating stain so you can see where you sprayed
Answer: Had never stained my concrete driveway nor the rock gardens around my home.
Question: Can you use this around shrubs and trees without killing the shrubs and trees
Answer: Roundup Extended Control Concentrate may be used for spot treatment to kill individual weeds around trees and shrubs, and in flower gardens. Do not allow spray to drift to desirable plants as it will harm them. This product should only be used around well-established plants. Do not use it around the root zone of plants that are less than 6 months old.
Question: The sprayer won't spray, any reason I can't put this in a spray bottle and use it that way? Widowed and appreciate your answers
Answer: yes you can do that.i got a bottle with a sprayer attached. it worked just great.i think round up puts them out too. you can use the bottle for almost anything. i hope this helps.
Question: Does Roundup kill or damage the beneficial microorganisms in soil that help make available important nutrients to food crops
Answer: No it does not kill microbes in the soil. In fact it helps farmers with no till and please let's not give IARC any credibility. It's not regulatory, and found sunlight, alcohol, bacon and salami was cancer causing. Follow the label and you will be fine.

Question: Does anyone know if this will work on bamboo? Yes, loose in the years. Ugh. Thanks
Answer: Ok there are two rates on the label. One is 6 ounces per gallon for spot treatments and the other is confusing and is more for spraying large areas. It says to use 7.4 ounces in 1 to 10 gallons of water and to spray that over 1000 square feet. Basically what that means is use whatever water between 1-10 gallons that it takes you to cover 1000 square feet at the pace you are working and the rate your sprayer is putting out spray. What is important is that you get 7.4 ounces of chemical over 1000 square feet. Call us at 800-264-5281 if you have any questions.

User questions & answers

Question: This is for two 24oz spray bottles, right
Answer: This stuff kills everything!
Question: Will this harm pacasyndra
Answer: I can says for sure that it is effective for common flower bed weeds, but I'm not sure of the types. This contains the same active ingredient as roundup - so if that product kills it, this one should too.
Question: kill ferns, moss, ground ivy
Answer: It is not effective when applied to the ground. It binds to the soil and decomposes before the roots can absorb it. You have to cut the tree down, drill holes in the stump, then pour this into the holes. You may need to repeat after 24 hours. But eventually it will die. I have successfully done this on 2 trees larger than yours.
Question: Can this be use on cactus without harming it
Answer: Cut whatever tree you want to kill to ground level, drill some nice fat holes in it (just don't drill through the wood and into dirt...obviously), and pour this undiluted into the holes. I also cover the holes with tape to prevent evaporation/dilution. The stump will soak it all up and die! :DI used this product in this manner to great effect on a Brazillian Pepper tree stump that was around a foot in diameter. I drilled about ten holes. Being the second time I cut the tree down to the ground, I wanted to be sure this time. One month later, there is no new growth like there was before.In short, yes, but don't be lazy about it and do it right ONE TIME. This stuff works!

Question: does it kill english ivy
Answer: Yes 2 bottles
Question: What product ratio do I use for driveway weeds
Answer: I do not know specifically about pacasyndra, but I do know that it did not harm vinca, lamium, or lysimachia.
Question: How long does it last
Answer: It does not kill ferns or ivy but I am not sure about moss
Question: Can I use it near a magnolia tree
Answer: This is formulated to only kill grass so a cactus should be ok. Having said that, I am careful when I use this around anything I care about. I use it mostly to kill grass that grows through my ground cover knowing that the cover will come back even if it dies. This has never harmed anything but grass in my experience and is a wonderful product.
