Kill Weeds and NOT Your Grass with this POTENT Combo
Top Takeaways
Safety is key when handling weed killers and fertilizers. Always read the product label, wear protective gear and keep children and pets away from treated areas.
Different types of weed killers are available on the market. They have different mechanisms of action and may be selective or non-selective, meaning they either kill only specific plants or all plants indiscriminately.
Organic weed killers are non-toxic and environmentally friendly, making them a great alternative for people who want to avoid the use of harsh chemicals on their lawn.
Lawn fertilization can help maintain healthy grass and prevent weed overgrowth, but it’s important to do it safely and strategically.
Regular lawn maintenance, such as mowing and watering, can help prevent weed growth and promote healthy grass.


A bucket of vinegar can be used to kill weeds. It’s an incredibly effective way to get rid of pesky grass and weeds in your yard. Vinegar is a mild acid that breaks down the cell structure of the plant, which kills it. 

The best part? Vinegar is inexpensive, easy to find at your local grocery store or hardware store and most importantly, safe for people and pets! 

You’ll need to grab some gloves, a pair of socks and goggles before you start applying this weed killer method because it will definitely burn if you get any on your skin!

Use 3 gallons of white vinegar per 1 gallon of water (1:3 ratio). Pour this mixture into a sprayer then apply it evenly over all affected areas where there are weeds growing or small patches where grass has died out due to lack of sunlight/watering from rain storms etc.

If using 5 gallons buckets fill halfway up with water then add 1 cup each time until reaching 5 gallons total volume; if using spray bottles mix together half full each time until reaching 1-gallon total volume such as 16oz cups x 8 = 128 ozs = 128 ozs x 2 = 256 ozs = 256 ozs x 0.5 = 512 fl oz (1 US fluid ounce)

Nail Polish

Nail polish can be a good option if you want to kill weeds and keep them from growing back. However, it’s important to know what type of nail polish works best for this purpose.

You’ll need the following supplies:

  • Nail polish remover (acetone)
  • Cotton balls or cotton pads
  • A plastic bag or container with a lid

Bleach is a highly effective weed killer and can be used in many areas of your yard. It’s also easy to apply, which makes it a great choice for amateur gardeners who want to make sure their weeds are gone for good. 

When using bleach as a weed killer, wear gloves and eye protection so that the bleach doesn’t ruin your skin or eyesight.

The first step in using bleach to kill grass and weeds is diluting it with water. Fill your spray bottle halfway with water and then add enough bleach solution (1 tablespoon per gallon) so that you get an even mix of the two liquids without creating too much foam on top of them when shaken together vigorously before spraying it onto any grasses or weeds you want dead in no time! 

When applying this mixture directly onto any unwanted plants, make sure not to aim at any nearby grasses because this could result in discoloration at best or death at worst due to overspray getting everywhere beyond just where intended!

After letting sit overnight under moist conditions (e.g., heavy dew), pull up dead patches using hand tools like rakes while wearing protective clothing such as long sleeves/pants/gloves plus rubber boots if possible; otherwise, just wear old clothes that won’t stain easily like jeans because they’ll still get dirty anyway despite precautions taken beforehand.”

Applying weed killers can be an effective way to remove weeds from your lawn, but it is important to know when it is safe to cut the grass afterward. Check out our guide on how long after weed killer can you cut grass to learn more about maintaining healthy lawns after using weed killers.


A vodka is a great option for killing weeds and grass. It’s cheap and has no side effects that might harm plants or people. 

The main drawback of vodka is that it can damage some types of soil, but most soils will be fine if you’re careful. If you’re worried about this, test the soil first before spraying it with vodka.

Vodka is also effective at killing weeds because it kills them by drying them out at their roots so they wither away quickly without leaving behind any residue on your lawn or garden beds like other chemicals do (which means no burning eyes!).

Vodka Brands for Killing Weeds

SmirnoffSmirnoff is a popular vodka brand known for its clean taste and affordable price. They offer a variety of flavors, including classic vodka, citrus, and berry flavors.
AbsolutAbsolut is a high-quality vodka brand that uses pure Swedish water and winter wheat. It’s a bit more expensive than other options, but the high alcohol content makes it an effective weed killer.
Grey GooseGrey Goose is a premium vodka brand that is made from fine French wheat and pure spring water. It has a smooth, well-balanced flavor and is more expensive than other options.
Tito’s Handmade VodkaTito’s is a gluten-free vodka that’s made from corn and distilled six times for maximum purity. It’s a bit pricier than other options, but it has a smooth taste and is great for making cocktails.
Ketel OneKetel One is a Dutch vodka that’s made from 100% wheat and distilled in copper pot stills. It has a crisp, clean flavor and is more expensive than other options.

Salt and Boiling Water

Salt and Boiling Water. Salt is a good way to kill weeds, but it can also kill your plants, so you need to be careful where you spray it. For this method, use a ratio of 1:1 salt to water (water should be at a rolling boil). Spray the solution on the weed and wait for it to die before replanting your grass seed or new plants.

Fertilizing a lawn can be a challenging task, but it doesn’t have to be. Check out our guide on how do I fertilize my lawn myself to learn more about the benefits of lawn fertilization and how to do it yourself.


Cornmeal is a great way to kill weeds, and it’s also a natural herbicide. Cornmeal can be applied in a variety of ways, but the most effective is mixing it with water and then spraying the mixture on your lawn or garden area. If you have hard surfaces that need treating, spread the cornmeal over them.

One thing to keep in mind when using cornmeal as an herbicide is that it takes time for the product to work its magic so if you want immediate results from this method, you might want to consider another option like Roundup or weed killer spray (see below).


Borax is a natural mineral that is mined from the ground. It can also be found in laundry detergents, as well as many other products that you would not expect to contain it! Borax is not toxic to humans, animals or plants. 

In fact, it helps keep your garden healthy by providing nutrients for lush plants and flowers with lots of lovely blooms.

Borax does have some negative side effects on certain types of insects, however: bees are particularly susceptible to death when exposed to borax because its alkaline nature burns their exoskeleton when ingested by bees.

Kawasaki lawn mowers are reliable and durable machines that can make lawn maintenance easy. However, learning how to turn on a Kawasaki lawn mower can be tricky for first-time owners. Check out our guide on how to turn on a Kawasaki lawn mower to learn more about getting your lawn mower started.

Rubbing Alcohol

Rubbing alcohol is a great tool for killing weeds on your lawn. It’s a type of alcohol, usually made with grain alcohol and water, that can be used to kill many types of plants. 

Rubbing alcohol is effective because it’s almost pure ethanol, which means it finds its way through the plant’s tissues and kills them from within.

Because rubbing alcohol is so effective at killing plants, you’ll want to use it sparingly. If you apply too much at once or too frequently, then you run the risk of damaging your grass as well as killing any potential weeds. 

To avoid this problem, we recommend using only about 1/4 cup per gallon when watering your yard!

White Vinegar and Epsom Salt

The following method is great for killing dandelions and crabgrass. Mix 1 cup of white vinegar with 2 cups of Epsom salt, then pour the mixture onto the weeds. The next day, sweep up any dead grass or weeds that have been affected by this mixture. Repeat if necessary.

Lawn rollers are a great tool for applying weed killers, but filling them correctly is key to effective lawn treatments. Check out our guide on how do you fill a lawn roller explained to learn more about properly filling and using lawn rollers for lawn care.

Vodka and Orange Oil

You can use vodka and orange oil to kill weeds.

To make this mixture, mix one-part of orange oil with three parts of vodka. Pour the mixture into a spray bottle and shake well. 

Spray the solution onto weeds that are actively growing or just coming back from winter dormancy, but wait until you see new growth before you mow again if your goal is to kill grasses as well as the weeds. 

The spray will be effective for 10 days after application if left on its own in sunlight; however, if you water down the area where you applied it during rainstorms or watering times (especially during hot weather), it’s going to be less effective over time because both rainwater and irrigation water dilute whatever concentration of active ingredients was put onto your lawn in an attempt to kill new growths underneath them.

Soap, Salt, and Vinegar Spray

Use equal parts of vinegar, salt, and soap. Mix together in a spray bottle and spray on grass and weeds. Wait 5 minutes, then wash off with water.

The vinegar will kill the weed’s roots, while the salt will cause it to shrivel up in no time! The soap acts as a surfactant so that everything sticks together well enough for you to rinse it away once you’re done applying your mixture.


The best way to deal with weeds and grass is by having a plan in place. Make sure you know what kind of plant you are dealing with before deciding on a method of removal so that you can be sure that it will work. If all else fails, just call a professional!
