Top 10 Natural Weed Killers – Comparison Table

The Best Natural Weed Killers On The Market

While there are ways to get rid of weeds without resorting to any products, they tend to be very time-consuming and tiring—who would want to spend hours just pulling up weeds? The following products are meant to put an end to pesky weeds that without compromising your family’s (and pets!) health!

Green Gobbler Vinegar Weed and Grass Killer

When you’re looking at natural alternatives, one of the first things you should look at is the ingredients list! It turns out that chemical herbicides or weed killers have glyphosate in them, which has been in use since the 1970s! While Environmental Protection Agency says that it’s safe for use as long as the label directions are followed, the International Agency for Research on Cancer (an intergovernmental agency under the World Health Organization) says that it’s still a potential carcinogenic or a cancer-causing substance for humans.

Green Gobbler Vinegar Weed & Grass Killer

It’s always better to be safe than sorry, which is why one of our picks is Green Gobbler Vinegar Weed and Grass Killer! It’s free of glyphosate, so you can be sure that it’s safe for you and your pets. In addition, it’s also been certified by the Organic Materials Review Institute so you’re extra assured of it being all natural.

Vinegar is one of the products that’s been touted as an effective, natural weed killer, however, most vinegars that you can buy in most stores are traditionally just 5%. Green Gobbler is four times stronger at 20%, so you’re guaranteed that it’s much more effective than your typical vinegar. It’s so effective that some people actually choose to dilute it a bit, meaning they can stretch it out and use it for longer!

Because of its strength, you can expect full desiccation or drying out of weeds within 24 hours or less. But be careful when spraying: it doesn’t discriminate, so it can also wipe out plants you want to keep! To be safe, make sure that you cover your plants with cardboard so that they don’t get any stray sprays. Also, make sure to protect yourself: concentrated vinegar can sting and burn if it gets into contact with skin, and especially sensitive areas like eyes.

To use, you simply have to attach the supplied sprayer to the container and you can start spraying. If you find it difficult to lug around the gallon, you can simply transfer the vinegar to a smaller pump sprayer. Again, remember that this is a non-selective weed killer, so it can also affect plants that you don’t want to desiccate, so mind where you spray! Once you’re done, drain any remaining vinegar from the sprayer, rinse it thoroughly, and let it dry. Close the container’s lid tightly to avoid any leaking before storing it away.

Doctor Kirchner Natural Weed Killer

Way back in 2003, Rudy Kirchner, a certified arborist or “tree surgeon”,  owned a landscaping company. As part of his job, he had to use weed killers—but unfortunately, he used chemical products and he found himself getting sicker and sicker as time went on. Eventually, because of all his health issues, he sold the company.

Doctor Kirchner Natural Weed Killer

Within a week of not using the harsh chemical weed killers, Kirchner found himself getting better. This put him on the road to developing a natural but effective weed killer. He was able to perfect his formula, which we now know as Doctor Kirchner Natural Weed Killer! Doctor Kirchner’s, founded in 2015, is a small family business that’s still run out of a garage and sold locally, but due to popular demand, they now sell on Amazon!

Doctor Kirchner is based on the usual natural concoction for weed killers—what grandma used years ago— but supercharged. It’s not exactly a secret recipe: it’s basically vinegar, salt water, and soap! The secret is in Kirchner’s use of good quality ingredients. For one, the vinegar he uses isn’t the same as what you can buy in stores—it’s highly concentrated and is six times stronger! He also uses clean saltwater fresh from the ocean, which he collects by taking his jugs to an inlet during high tide!

Because it’s a mix of natural ingredients, Doctor Kirchner is safe for the environment. It’s biodegradable and phosphate-free! In 2017, it was even recognized by the non-profit Keep Indian River Beautiful as the Environmental Small Business of the Year for its contribution to preserving lagoons and rivers by providing a safe alternative to toxic weed killers. It’s also safe for pets—your dog can get right back to running around the garden as soon as the weed killer dries! And of course, you can be sure that it’s safe for you and your family as well.

We recommend simply buying the larger gallons instead of getting the small ones with a spray bottle, because Doctor Kirchner doesn’t expire! Simply invest in your own sprayer so that you won’t lug around the huge gallon around all the time. No need to do any mixing or other preparations for this, just spray at the weeds you want to get rid of and wait for the magic to happen! Store in a cool, dry place away from sunlight to avoid any potential mishaps.

Natural Armor All-Natural Weed and Grass Killer

Natural Armor is another small, family-owned and run company that offers yet another non-toxic weed killing solution. However, this company has been around for a longer time and has quite different beginnings: Natural Armor’s first product was actually animal repellent. Having been successful with that, they’ve now branched into different natural alternatives to chemical products.

Natural Armor All-Natural Weed and Grass Killer

The main ingredient in Natural Armor is good old vinegar, but like with the others on this list, it uses a more concentrated version of the ones you’d find on the grocery store shelves. But don’t get confused: the formula of Natural Armor is described as concentrated, but it isn’t a concentrate. A concentrate would need to be diluted with water at a certain ratio before it should be used, but Natural Armor is ready-to-use as is!

In addition the vinegar, Natural Armor also counts citric acid and clove oil among its ingredients. The company prides itself on being the first to make use of essential oils in their products. They started using them when they realized that there are certain herbs that without any extra effort already have the effect that they wanted, whether it was repelling pests or preventing the growth of weeds. Clove oil has proven to be great, natural way to suppress weeds and at the same time keep away any possible pests like mites!

My favorite thing about Natural Armor is how quickly it works: I spray it on generously, and after a couple of hours (usually around four),  the weeds are dead! From bright green, the weeds are now yellow and brown and wilted, which is exactly what we’re looking for in the best natural weed killer! Lots of other people have also compared it to chemical weed killers, reporting that it actually works much faster.

Our only issue with Natural Armor is something that can very easily be addressed: the sprayer! There’s a tendency for the product to clog up the sprayer, so you may want to get a replacement instead. Otherwise, Natural Armor’s website and several other reviews mention that shaking the bottle well before use will get rid of this issue. You also simply run it under tap water to get rid of the build up if it’s already there.

As we mentioned earlier, simply take Natural Armor and spray directly. It also comes in several gallon sizes, so go get the bigger sizes if you’ve got quite a big weed problem to tackle!

TradeKing All-Natural 30% Vinegar

If you’re looking for more bang for your buck, you probably want something that’s multipurpose. After all, weeds are not the only things that can wreak havoc on your home and garden! If that’s the case, you may want to go with something a bit more basic than the others on this list: concentrated vinegar!

TradeKing All-Natural 30% Vinegar

By now, you might have noticed that all our recommendations for the best natural weed control have a particular ingredient that’s prominent. Vinegar is the classic natural weed killer, and it’s been used by our grandparents to make sure that those pesky weeds don’t take over the garden. Of course, like we’ve mentioned before, the vinegar that you can buy in the grocery won’t cut it—it’s too weak, so it won’t do much unless it’s in copious amounts.

TradeKing focuses on the main weed-killing ingredient and makes it great: it’s pure vinegar. It’s the highest strength available on the market at 30% concentration. It is quite powerful, so if you’re lucky enough to not have too many of those hard-to-kill weeds, you can dilute it to a weaker strength so that it can last longer. But if you have to deal with larger weeds, it’s better to leave it at full strength for best results.

Since it’s pure vinegar, it can be used in a variety of ways. Not only is it helpful in the garden, but it’s also helpful in other parts of your home! Vinegar has been known to be incredibly effective for deep cleaning various surfaces, and it can even be used to brighten up your laundry!

Because TradeKing is just vinegar, it can be a bit overpowering. Make sure that you’re well-protected before applying on your garden, and as previously mentioned, you can choose to dilute it if you don’t need it at full strength. The smell is also a bit overwhelming, so I suggest that you put a mask on to help. But overall, it isn’t poisonous and won’t cause harm the way chemical herbicides would. Plus, you get the bonus of having some heavy-duty cleaner on hand in case you need it!

Eco Garden Pro Organic Weed Killer

With this brand name, you can be sure that this weed killer is environmentally-friendly! Eco Garden Pro Organic Weed Killer makes use of two classic natural weed killers: vinegar and salt! Of course, only the best ingredients are used, namely organic white vinegar and Himalayan rock salt. These two ingredients, which are pharmaceutical grade, are mixed together in a ready to use concentrate, so there’s no messy mixing needed!

Eco Garden Pro Organic Weed Killer

What I appreciate about Eco Garden Pro is their focus on quality assurance, so that you’re sure to get a quality product every time. On the odd case that it doesn’t seem to be working (which would be an incredibly rare case!), you can simply get in touch with them and they’ll give a full refund. It’s a 100% satisfaction guarantee!  They also put a lot of emphasis on sustainable sourcing and green manufacturing practices, which is definitely a big plus when you want to do your part in preserving the environment for future generations.

This is a non-selective natural herbicide, so take care when it comes to spraying your garden. Don’t spray this on plants you want to keep! So long as you don’t end up spraying on your good plants, there’s no danger to them that Eco Garden Pro will pose to them. It’s 100% biodegradable and is phosphate-free, making it safe for groundwater. After applying, once dry, your kids and pets can start playing in the yard again without fear of any nasty effects from typical chemical weed killers. It’s made of ingredients that are Generally Recognized As Safe by the US Food and Drug Administration, so you can rest easy.

Since it’s ready to use, all you need to do is spray it on the weeds you want to get rid of, then let it work its magic. You’ll see results within 24 hours. The best time to spray this on would be on sunny days, since sunlight will help activate the acetic acid and boost the weed-killing along. But the sun isn’t necessary, since it will still work even on cloudy days—simply spray a bit more than usual.

Epsoma Organic Weed Preventer

This product is a little different from all the other products on this list: instead of being a weed-killer, it’s a weed-preventer. This means that it will keep those pesky weeds from sprouting up again! Unfortunately, this also means that it won’t do much for weeds that are already growing in your garden.

Epsoma Organic Weed Preventer

Since this is a pre-emergent product (aka to be used before the weeds emerge or sprout), it should only be used on lawns that are already established. An established lawn is basically a lawn that already has a good growth of grass, which is the good plant you want to keep. Again, the Epsoma Organic Weed Preventer won’t harm plants that have already been established.

One of my favorite things about Epsoma Organic Weed Preventer is that it doesn’t just prevent weeds from growing, but it actually feeds my lawn! Epsoma started out as a fertilizer company way back in 1929, and they’ve been working at improving their products ever since. They’ve been organic from the beginning, so they’ve definitely done a lot in keeping the environment safe from harsh chemicals. Their weed preventer is made out of 100% pure corn gluten meal, so it also serves as an excellent way to green lawns. Not only will you have a weed-free lawn, but it will also be a gorgeous green hue that will also have your neighbors green with envy!

Because of its nature, this is a product that needs a bit more care in applying in order to get the best results. Before applying, make sure that your lawn or garden is already weed-free. We’ve already listed down several products here that you can use to kill weeds that have already grown. Make sure also that your grass or good plants have already started growing, since this product will keep any others from germinating. Epsoma advises two generous applications a year: once during early spring, and once during early fall. It’s also ideal to apply the product when your lawn is freshly mowed, and if rain isn’t in the forecast soon, water it slightly for best results.

Nature’s Avenger Organic Weed Killer Concentrate

We know what you’re all thinking…no, this is not made by Marvel. But its history does make for a good origin story though. Over 10 years ago, a landscaping business owner discovered what would be known as this weed killer’s unique superpower: citrus oil! Once he knew that his product had been the perfect ‘avenger’ against gardeners’ enemies, he got it patented and now owns a new company called ‘Cutting Edge Formulations’ that uses the Avenger brand.

Nature's Avenger Organic Weed Killer Concentrate

Labeled as ‘d-limonene’, this oil is described to dehydrate and kill unwanted weeds, grasses and broadleaves by naturally stripping away its waxy cuticle. Nature’s Avenger is environmentally-friendly, biodegradable, and the best part? It smells like a freshly squeezed orange!

The list of places where this can be used is quite extensive, but to name a few, it can be used in shrubs, flower beds, driveways, sidewalks, and even in golf courses! It is also known to be faster and just as effective as other and more common alternatives – dilute, spray, and see the effects in just two hours!

As it is with other weed killer products, it is easy for spray products to accidentally touch plants you’d like to save. Bottles are also designed in such a way that you can see wherever you are spraying. But because this weed killer’s spray nozzle is not the best one out there, we recommend that using an old box with open ends to limit your spray zone and secure unwanted weeds. Also watch out for drippings of this weed killer as one drop could kill your favorite vegetation.

And if you’re not just a plant lover, but also an animal lover, we’ve got some good news for you: This weed killer can be used around pets as well! No need to worry about invasive smells affecting your 2- or 4-legged friends.

There are three sizes of Nature’s Avenger Organic Weed Killer Concentrate that you could choose from: A 24-ounce spray bottle, a 32-ounce bottle, and a 1-gallon tub which includes a spray nozzle. Though whichever one you buy, you will be feeling like Iron Man defeating the Thanos that is your weeds.

Weed Slayer Organic Herbicide Natural Grass and Weed Control

This next product not only kills—it slays (pun intended). Produced by Agro Research International, CEO Marc Lajeunesse began his journey of this product’s development by helping Colombian farmers turn their coca harvest used for illicit drugs into something that can be sold legally and for profit. The most famous outcome of what happened was ‘Stevia’, the sweetener that people have come to know and love.

Weed Slayer Organic Herbicide Natural Grass and Weed Control

Over the course of Stevia production, Lajeunesse experienced many challenges in growing the crops: Harvests were inconsistent and many crops died before they could even be harvested. To combat this, he expanded his company to accommodate crop protection products like the Thyme Guard, the Stim Guard, and the Weed Slayer.

What makes the Weed Slayer special? This natural and plant-based herbicide contains eugenol, which is an essential oil extracted from clove and molasses. It comes in two 2.5-gallon containers, one being the Weed Slayer and another the Agro Gold WS, a biological amendment.

To finally control your grass and weed problem, all you have to do is to mix 20 to 25 gallons of water and one to two quarts of the Weed Slayer and the Agro Gold WS per acre (as always, don’t forget to protect the plants you want to keep!). Mix the water and the solution by shaking both jugs and pour contents into a tank.

We do warn you though: Compared to the previous weed killer, results will take a little longer; about 10 to 14 days for its full effect, to be exact. But the reason for why it takes this long is because it gives the user more control by killing the root ball and not just what can be seen above ground.

It is also necessary for us to discuss the importance of water pH levels in using the Weed Slayer. For best results, pH level three to four would be ideal. If your water does not have this pH level, we recommend you use a little citric acid from oranges, lemons, and the like. Feel free to use a pH meter or litmus papers till you reach the ideal level. Once reached, mix with the product, and apply away.

EarthSafe All Natural Organic Weed Killer Salt-Free

“Relentless on weeds, respectful of the planet.”

As the name and its tagline suggests, this weed killer is one of the most environmentally-friendly ones on Earth. Created by the company MillCro, the EarthSafe Weed Killer is all organic, natural, and offers the safe control of unwanted weeds and plants minus the risks posed by chemical-based products! Talk about doing your part in the world!

EarthSafe All Natural Organic Weed Killer Salt-Free

MillCro produces water and vinegar-based weed killers, with EarthSafe being a vinegar-based one. What this means for you green thumbs out there is that you don’t have to be concerned about having your pets roam around the front or backyard, or having your kids play outside, or even your friends and family being exposed to the scent of the weed killer—because, rest assured, they will be safe and sound.

There are two options for those interested in buying, you can either get the EarthSafe in a 1- or 2.5-gallon container. To use this weed killer, pour the contents into a spray of your choice (ideally, it should be properly-pressurized for better aim). Once sealed, apply generously to the unwanted weed grasses in your yard and see immediate results after an hour and a half! This weed killer can actually work against multiple types of broad-leaf weeds and weed grasses. It is best used in patios, swimming pools, driveways, and essentially anywhere.

Here’s a free tip from us: Since the product contains no chemicals, it may not be as effective for those who have really bad weed problems. You can also check out their water-based weed killer called the ‘OceanSalt Organic Weed Killer’—both are safe for your furry friends. But unlike EarthSafe which is salt-free, OceanSalt contains ocean water, sea salt, and vinegar.

On the bright side, MillCro believes in their products so much that it has a “no questions asked” lifetime warranty policy for both! So in the slight possibility that the EarthSafe weed killer doesn’t work, just get in touch with the number on their website and someone from their team will get back to you to address your questions and concerns.

OrganicMatters Natural Weed Killer

Most people are skeptical when it comes to natural products, but OrganicMatters Natural Weed Killer is a product that turns them into believers. It’s one of the fastest acting products in the market, but it’s still safe for the environment, including pets and people.

OrganicMatters Natural Weed Killer

OrganicMatters Natural Weed Killer’s main ingredient is good old vinegar. Of course, as with the other similar products on this list, it isn’t the same vinegar as the ones you can buy in a grocery store. The product is true to its name by being fully organic, containing no glysophate that’s potentially dangerous to you and the environment.

OrganicMatters has also found a way to make their product more effective and efficient by making it quick-drying, which means that your kids and pets can play in the yard sooner rather than later! It also means that there’s less chance of it being washed off due to a sudden rain shower soon after you apply it. No need to double-check the weather forecast before applying this product!

This product is no doubt impressive—but, you don’t even have to take my word for it with all the positive reviews that it’s gotten from so many people! It’s quick-dry formula really does make a difference. It’s quick to kill unwanted weeds that after just a few hours, the weeds are brown and by the next day will definitely be dead. This is just after just one application! This is definitely some powerful, effective stuff.

As with all vinegar-based products, even though it’s all-natural, take care in applying it. Concentrated vinegar products tend to have a powerful smell that can sting both eyes and nose, so if you’re particularly sensitive, it’s better to wear a mask and goggles in addition to the usual gloves. OrganicMatters Natural Weed Killer also comes with a heavy-duty spray trigger that’s great for targeting just the weeds you want gone, though you may want to transfer it to a smaller container if you chose to go with the gallon-sized one to make it easier to carry around.

Things To Consider When Choosing The Best Natural Weed Killer

We’ve given you a lot of options for natural weed killers, all of which are good places to start. If you’re still unsure of which one to choose, here are some things to consider so that you can choose the best natural weed killer for you:

  • What Kinds Of Weeds Do You Have?

It helps to know more about your yard and the stuff that tends to grow there. If you don’t know what the different weeds are, you can do a quick Google search for images of different weeds so you can see which ones are growing in your garden. Most weed killers will have a list of weeds that it targets best, and you can also look through the reviews to see which weeds its most effective against as per actual users!

  • How Big Is Your Garden?

This is more about how much product you’ll need rather than what product you need. Still, it’s something to consider, especially since different weed killers can come in different quantities. For example, if you have a small lawn and garden, you might be fine with getting a quart instead of a gallon. If you have a much bigger area to cover, such both a front yard and a backyard, it might be better to go with a bigger quantity.

  • What Kind Of Weed Control Do You Need?

There’s a huge difference between pre-emergent and post-emergent weed control! Pre-emergent is about weed prevention, while post-emergent is about weed destruction. If you already have lots of weeds growing in your yard, or even if they’ve just sprouted, you will need the latter. These are usually the vinegar-based ones, since they target grown plants. If you have a weed-free yard and want to keep it that way, go with pre-emergent weed control. These will stop plants from germinating, so don’t use these on a freshly planted garden.

  • Do You Need To Protect Your Other Plants?

Of course, the answer to the above will probably be a resounding yes. Unfortunately, we haven’t found a natural weed killer that is selective, meaning that it will only kill weeds but not other plants around it. To make sure that your good plants are safe, spray weed killers only on windless days. This will prevent the unnecessary and unwanted transfer from weeds to your plants. It’s also good to choose products that dry quickly so that they don’t transfer! If you’re using weed killers to control weeds that sprout between pave stones, a non-selective one will work just fine and you have nothing to worry about.

  • Do You Already Have Other Equipment For Weed Killing?

If it’s your first time dealing with a garden, you may not yet have certain things that you’ll need to make good use of your weed killer. For example, a good sprayer. Some weed killers don’t come with a sprayer, as they’re meant to be refills or transferred to smaller containers. If you’re torn between two brands, consider what other extras they have to offer—read up on reviews to figure out which has a better quality sprayer, for example.

  • What Do You Already Have On Hand?

Natural weed killers can be made with household objects, and you can strengthen the weed killer you buy by making use of what you already have at home. Of course, different products will have different price points, so it may be smarter for you to simply choose a cheaper product that you can bolster with the stuff you already have lying around. Reviews will give you a better idea of what the product might possibly need help with, such as surfactants (getting the product to stick on the weeds they need to kill) or maybe adding more salt.

  • Are You Sensitive To Particular Ingredients?

You might not be outright allergic to any of the main ingredients in natural weed killers, but they do tend to be quite powerful—vinegar, in particular, smells quite strongly and can irritate your eyes and nose. If so, go with those that don’t just depend on vinegar, like those with essential oils. Certain essential oils are very helpful in preventing unwanted weed growth as well, and it’s well worth the extra price if it’s easier for you to use!

How To Make Natural Weed Killer At Home

If you’re the DIY type, you might want to try your hand at making your own natural weed killer at home! You can probably do it right now too, since it’s very likely that you already have the needed ingredients lying around.

To make your own natural weed killer, gather the following: vinegar, salt, and dishwashing liquid. That’s it! You’d also need a spray bottle so that you can get to those weeds already.

Now, don’t just go mixing the ingredients willy-nilly. What do you want your weed killer to do, other than just simply kill those pesky weeds? It will make a difference in your concoction if you want to replant in the area in the near future, or if you just want to keep the area plant and weed-free forever (well, a very long time at least).

If you want to get rid of weeds in a potential flowerbed, simply mix a bottleful of vinegar with about a spoonful of dishwashing liquid. Spray these copiously on weeds on a hot, sunny day—make sure to really soak them! The sun will help bake in the vinegar and get the weed killer going.

For places that you don’t want anything to grow in, like in between paving stones or gravel walkways, you’ll need the salt. You’ll need a good amount of salt, about two cups for every gallon of vinegar! Dissolve the salt in the vinegar, then add the dishwashing liquid—just a small amount will do, such as a spoonful. Saturate the area with the weed killer and you’re done! The salt will help sterilize the soil in those areas so that nothing will grow back.

Conclusion

Most people think that going natural also means going for the less effective products, which simply isn’t true. Scientific advancements have also made these natural concoctions incredibly effective, but at the same time also friendlier to the environment. After all, what’s the point of taking care of our garden if we’re slowly making ourselves sick with all the toxic chemicals?

Hopefully, more and more people become aware of these products which are helpful in keeping weeds at bay while not harming any other creatures and not having any long-term negative effects. Simply choosing to go with a friendlier product is a great step towards a more sustainable world so that our kids can keep enjoying it.

Let’s start saving the world by going natural!
