In the UK, gardeners often have to tackle the everyday task of disposing of weeds in their gardens. While commercial herbicides offer quick fixes, they come with environmental concerns. This article delves into how to make homemade weed killer, providing eco-friendly solutions that are both effective and easy to prepare. Using everyday household items, we’ll explore methods that are not only kind to the environment but also gentler on your pocket if sticking to a tight garden budget. In this article: [
Hey there, fellow garden warriors! If you’ve been battling unwanted grass or pesky weeds in your yard and you’re lookin’ for a natural fix, you mighta stumbled across apple cider vinegar (ACV) as a possible solution. So, let’s get straight to the big question: Will apple cider vinegar kill grass? Yup, it can, but it ain’t a magic bullet. ACV’s got some punch thanks to its acidity, which can mess with grass by drying it out and disruptin’ its growth. But, hold up—it’s not gonna wipe out your whole lawn overnight, and it works best on small patches or young grass. Stick with me as we dive deep into how this kitchen staple works in the garden, the good, the bad, and whether it’s worth a shot for your green space.
Why Even Consider Apple Cider Vinegar for Grass Control?
Let’s be real—nobody wants to dump a bunch of harsh chemicals on their lawn if they can help it. Maybe you’ve got pets runnin’ around kids playin’ in the yard or you just wanna keep things eco-friendly. That’s where ACV comes in. It’s a natural option, sittin’ right in your pantry, and folks have been buzzin’ about it as a weed and grass killer for ages. But before you go pourin’ it all over your driveway cracks or flower beds, let’s break down what it actually does.
- It’s Acidic, Baby! ACV contains acetic acid, which is the main player here. This stuff can mess with a plant’s cell walls, suckin’ out moisture and basically makin’ the grass or weed shrivel up.
- Non-Selective Killer: Here’s the catch—it don’t care if it’s grass, weeds, or your prized roses. If it touches a plant, it might harm it.
- Spot Treatment Vibes: It’s best for targetin’ small areas, like grass poppin’ up in sidewalks or tiny weed patches, not for big ol’ lawns.
How Does Apple Cider Vinegar Work on Grass?
Alright, let’s get into the nitty-gritty. When I first tried usin’ ACV on some stubborn grass in my garden path, I was curious how a simple vinegar could do the job. Turns out the acetic acid in ACV messes with the plant on a cellular level. It breaks down the protective barriers of the grass, causin’ it to lose water fast. Imagine it like givin’ the grass a bad sunburn—it just can’t recover if the damage is bad enough.
Here’s the deal though: household ACV usually has about 5% acetic acid, which ain’t super strong. Compare that to industrial vinegar solutions with 20% or even 30% acetic acid, and you see why the stuff from your kitchen might take a few tries to work. It’s more effective on young grass or weeds that ain’t fully established yet. Older, tougher grass? It might just laugh at your ACV spray.
Factors That Make or Break ACV’s Grass-Killin’ Power
Not all grass is gonna keel over the same way when you hit it with ACV. There’s a buncha things that decide if it’s gonna work or flop. Here’s what I’ve noticed after messin’ around with it in my own yard:
- Concentration Matters: The higher the acetic acid level, the better the results. Your regular ACV might need to be used straight up or only slightly diluted to pack a punch.
- How You Apply It: Pourin’ or sprayin’ it directly on the grass blades works better than just splashin’ it on the soil. Get it right on the green stuff.
- Type of Grass: Some grasses are tougher than others. Broadleaf weeds often die easier than grassy types, which can be more stubborn.
- Weather Playin’ a Role: Hot, dry days are your friend here. The heat helps the acid do its thing faster. If it’s rainy or cool, the effect might be weaker.
- Soil Situation: If you’ve got sandy soil, the ACV can sink in and hit the roots better. Clay soil, though? It holds water and might dilute the vinegar, makin’ it less effective.
Does Apple Cider Vinegar Kill Grass Better Than White Vinegar?
Now, I’ve had folks ask me if there’s a big difference between usin’ apple cider vinegar and plain ol’ white vinegar for grass control. Honestly, they’re pretty dang similar when it comes to the active ingredient—acetic acid. Both usually sit around 5% acidity in the stuff you buy at the store. White vinegar might edge out a tiny bit since it’s often purer, without the extra flavors or bits in ACV, but we’re talkin’ small potatoes here. I’ve used both, and I ain’t seen a huge gap in results. Pick whichever you’ve got handy, or whichever smells less funky to ya while you’re sprayin’!
Step-by-Step: How to Use Apple Cider Vinegar to Kill Grass
If you’re itchin’ to try this out let me walk ya through how I do it. It’s pretty straightforward, but you gotta be careful not to mess up other plants nearby. Here’s my go-to method
- Grab Your Gear: Get some ACV (straight from the bottle works best for small spots), a spray bottle or a small watering can, and maybe some gloves if you don’t wanna smell like vinegar all day.
- Mix It Up (Or Not): For tougher grass, I use it undiluted. If I’m worried about nearby plants, I’ll mix 1 part ACV with 1 or 2 parts water to tone it down a bit.
- Pick the Right Day: Aim for a sunny, hot day with no rain in the forecast. Windy days are a no-go ‘cause the spray might drift to stuff you don’t wanna kill.
- Target the Grass: Spray or pour the ACV right on the grass you wanna zap. Focus on the leaves and avoid soakin’ the soil too much if you’ve got other plants around.
- Wait and Watch: It ain’t instant. Give it a day or two. You might see the grass startin’ to brown and wilt. If it’s still kickin’, hit it again with another round.
- Clean Up Dead Stuff: Once the grass is toast, pull it out or rake it up so it don’t just sit there lookin’ ugly.
Quick Tip: I like addin’ a tiny squirt of dish soap to the mix sometimes. It helps the vinegar stick to the leaves better, uppin’ the chances it’ll work.
Pros and Cons of Usin’ Apple Cider Vinegar on Grass
Before you go all in, let’s weigh the good and the not-so-good. I’ve been down this road, and trust me, it’s worth knowin’ what you’re signin’ up for.
The Good Stuff
- Natural and Cheap: ACV is somethin’ most of us already got at home, and it’s way less toxic than chemical herbicides.
- Works on Small Areas: Perfect for spot-treatin’ grass in cracks, paths, or tiny patches where you don’t want nothin’ growin’.
- Eco-Friendly Option: It breaks down quick in the environment, so you ain’t leavin’ nasty residues behind.
The Not-So-Good Stuff
- It’s Slow: Don’t expect overnight miracles. It can take days or multiple tries to kill off grass, especially if it’s tough.
- Kills Everything: It don’t pick and choose. Splash it on your lawn or flowers by accident, and you’re gonna have a bad time.
- Soil pH Mess: Usin’ it a lot can make your soil too acidic, which ain’t great for growin’ healthy grass or veggies later on. Most plants like a pH around 5.8 to 6.5, and ACV can throw that off.
- Not for Big Jobs: If you’ve got a huge area of unwanted grass, this ain’t the tool. It’s too slow and fiddly for that.
What If Apple Cider Vinegar Don’t Cut It?
Sometimes, ACV just ain’t gonna do the trick, especially if you’re dealin’ with a big patch of grass or super stubborn types. I’ve been there, frustrated as heck when it didn’t work as fast as I hoped. So, here’s a few other tricks I’ve tried when ACV falls short:
- Boilin’ Water Blast: Grab a kettle, boil some water, and pour it straight on the grass. It scalds the heck outta it and kills it quick. Just watch out—it can hurt nearby plants and even mess with good soil bugs.
- Solar Power (Sorta): Lay down clear plastic sheets over the grass durin’ the hottest part of the year. The heat gets trapped and cooks the grass dead. Takes a few weeks, but it’s hands-off.
- Chemical Herbicides: If you’re cool with goin’ the chemical route, these are usually faster and stronger. Just be super careful—read the label, keep pets and kids away, and know it ain’t as green as ACV.
- Manual Pullin’: Old-school, but effective. Get down there with a trowel or your hands and yank that grass out by the roots. Works best after a rain when the soil’s soft.
Safety First: Things to Watch Out For
I gotta throw in a lil’ reminder here—ACV might be natural, but it ain’t all sunshine and rainbows. When I first started usin’ it, I didn’t think twice about where I sprayed, and I accidentally browned some nearby plants I liked. Lesson learned! Here’s how to keep things safe:
- Protect Other Plants: Use a piece of cardboard or somethin’ to shield plants you wanna keep while sprayin’. That stuff don’t discriminate.
- Keep Kids and Pets Away: It’s generally safe, but you don’t want lil’ ones or furry friends gettin’ into it. It can upset stomachs if they mess with it, and you don’t want ‘em trackin’ it around.
- Don’t Overdo It: Usin’ too much over time can turn your soil into an acidic mess. Test your soil pH now and then if you’re hittin’ the same spot a lot.
- Watch Your Skin and Eyes: It’s just vinegar, but it can still sting if it gets in your eyes or on a cut. I usually wear gloves and keep my face clear when sprayin’.
My Personal Take: Is It Worth It?
Look, I’ve tinkered with ACV for grass control in my own backyard, and I’ll be straight with ya—it’s got its place, but it ain’t a cure-all. For small spots, like grass creepin’ into my patio cracks, it’s been a handy, cheap fix. I mix it up, spray it on a hot day, and usually within a couple days, that grass is lookin’ sad and dead. But when I tried it on a bigger patch near my veggie bed, it was a slog. Took multiple sprays, and I still had to pull some by hand. Plus, I got paranoid about the soil gettin’ too acidic for my tomatoes.
If you’re just dealin’ with a lil’ unwanted grass here and there, give ACV a whirl. It’s low-risk, easy to try, and you prob’ly already got some in the cupboard. But for bigger jobs or if you’re super protective of your lawn, you might wanna pair it with other methods or skip straight to somethin’ stronger.
Wrappin’ It Up: Apple Cider Vinegar for Grass—Yes or No?
So, back to the big question—will apple cider vinegar kill grass? Yeah, it can, but it’s more of a slow-and-steady player than a knockout punch. Its acetic acid can dry out and kill grass, especially young or small patches, but it’s not gonna tackle a whole lawn or tough, established growth without a lotta effort. You gotta use it right—straight or lightly diluted, on hot days, directly on the leaves—and even then, it might need a few rounds to get the job done.
We’ve covered the hows and whys, from how ACV messes with grass on a cellular level to the pros (cheap, natural) and cons (slow, non-selective). I’ve shared my own trial-and-error moments, and I hope it helps ya decide if this is the route for your garden. If you try it, start small, protect your good plants, and don’t expect miracles overnight. And hey, if it don’t work out, there’s always boilin’ water or good ol’ elbow grease to fall back on.

Boiling Water Technique
Boiling water is an effective home made weed killer, especially on pathways and pavements where surrounding plants won’t be harmed. If you are targeting a cluster of weeds among other plants, be sure to avoid harming the plants you wish to keep.
A pro tip: repurpose the water used to boil vegetables after use.
- Ideal for: Walkways, patios, driveways, garden borders, isolated weed patches.
- Our Take: Simple, cost-effective, and eco-friendly.
One of the main features of lemon juice is citric acid, which can help to kill weeds.
Recipe: Extract juice from approximately five lemons or use pre-packaged lemon juice.
- Ideal for: Walkways, pavements, driveways.
- Our Take: Opt for pre-packaged juice for a quicker solution; otherwise, it can be a bit time-intensive.
Baking Soda & Vinegar Mixture
Some communities are exploring vinegar as a sustainable homemade weed control solution in urban areas. For better results, combine it with baking soda, salt, or lemon juice.
Recipe: Mix one part baking soda with two parts white vinegar. Add lemon juice if desired.
- Ideal for: Young weeds or those in paved regions.
- Our Take: Budget-friendly, though it has a strong odour.
Mulching is the process of layering the soil with material, and is a great way to suppress weeds. Options range from homemade compost to specialised weed barriers. Mulches not only deter weeds but also retain soil moisture and can provide nutrients. As earthworms integrate the mulch into the soil, they enhance its quality.
- Ideal for: General garden areas.
- Our Take: Effective and offers multiple benefits.
Additionally, there are other non-chemical alternatives like flame guns and battery-operated weed burners for safe weed elimination. And if you like our homemade garden remedies, you can also learn about how to use rooting hormone next!
Kill Grass With Vinegar
FAQ
Will apple cider vinegar hurt grass?
It might look like vinegar is an easy way to get rid of weeds quickly, but it can be dangerous. It can kill small weeds, but it hurts nearby grass, soil, and plants. When spraying vinegar, be careful, especially in places where pets play or where you want to grow plants again.
Will grass grow back after vinegar?
Yes, grass will likely grow back after being sprayed with vinegar, as vinegar is a contact herbicide that burns the top growth but doesn’t typically kill the roots of established grasses. The grass may require several applications of vinegar to destroy its root system, and even then, the affected area’s soil may temporarily become more acidic, slowing recovery. To promote faster regrowth, you can neutralize the soil’s acidity by drenching the area with water or applying a baking soda solution.
How fast does vinegar kill grass?
Vinegar can kill grass within hours by burning the foliage, but the speed depends on the acetic acid concentration, grass type, and conditions. Household vinegar (5% acetic acid) will cause damage in about 24 hours, leading to brown spots and leaf curling, while stronger horticultural vinegar (20-30% acetic acid) can cause complete death much faster, even within hours.
Why do people put vinegar on their grass?
Vinegar is an indiscriminate herbicide, pesticide and fungicide. It also has antibacterial properties. It will kill EVERYTHING, including beneficial microorganisms in the soil that plants need to convert nitrogen into a form they can use. In most states professionals must have a license to use it as an herbicide.
Does apple cider vinegar kill grass?
They may make plants, grasses, and weeds dieback, especially if you live in a sunny climate. Apple cider vinegar is unlikely to kill your grass completely. It will make the blades turn yellow but won’t affect the roots, so it’s most likely that your grass will grow back in time.
Can I use vinegar on my lawn?
If you’re considering using vinegar on your lawn, be warned that repeated applications of the vinegar solution can cause soil acidity, affecting the pH balance your grass needs. An acidic soil environment is not ideal for grass growth, and it can cause your lawn to turn yellow or brown, leading to grass death in the long run.
Can apple cider vinegar kill weeds?
Apple cider vinegar can be sprayed on weeds as it acts as a contact herbicide. Alternatively, you can drench the soil in apple cider vinegar to kill the weeds. Spraying weeds is likely to be the most effective method as the sun will cause the acidity of the vinegar to burn the weed.
How does vinegar affect lawn grass?
Vinegar can significantly impact lawn grass, depending on its concentration and the particular type of grass. Understanding how it works helps you make informed decisions. Vinegar’s active ingredient, acetic acid, disrupts plant cellular function. It draws moisture out of plant cells, causing wilting.
Can vinegar be used as a weed killer?
When using vinegar as a weed killer, it’s also important to take into account its non-specific damage to all green plants. Vinegar is not selective and can harm desirable plants, including grass. Its broad-spectrum impact on greenery limits its efficacy as a targeted weed control method.
Does vinegar kill broadleaf grass?
Even with horticultural vinegar, the roots of the grass are not damaged. Instead of vinegar, use 2,4, D to kill broadleaf grasses such as St. Augustine. Use caution, as it will also kill flowers, which are broadleaf plants, too. To kill all types of grass, use a herbicide containing glyphosate.
