There are countless homemade weed killer recipes UK gardeners have at their disposal when a pesky problem pops up in the yard and you don’t want to use an excessively strong weed killer to get a grasp on it. From rock salt for weeds to vinegar, the possibilities are endless.
But does bleach kill weeds? You might have heard of this common household item being used to control weeds, so why is bleach a good weed killer? It essentially breaks down the plant structure and sucks the moisture out of it.
While a bleach weed killer recipe works well against a variety of weeds, it’s important to ask yourself - at what cost? The long-term effects of using bleach as a weed killer may not be worth it.
We’ll help you weigh all this and more below and offer tips on using bleach to kill weeds, discuss how long for bleach to kill weeds, and more importantly, we’ll share alternatives to control weeds without negatively affecting nearby vegetation, the soil itself, or our environment as a whole.
One of these is our acetic acid weed killer at Jennychem, Weedex Super. It’s non-toxic after it dries so you can apply it with peace of mind, whether you need a bramble weed killer or a dandelion killer for lawns. Regain control of your yard today!
The Basics of Bleach (Sodium Hypochlorite)
First things first, what is bleach? At its core, this is sodium hypochlorite - a powerful chemical commonly used for disinfecting, whitening fabrics, and removing stains. It’s something almost every household in the UK keeps on hand.
Bleach breaks down organic material through oxidation to essentially kill any bacteria, mould, or fungi. As a biocide, it can basically kill anything in its path - which is why the concept of using a bleach weed killer recipe is so intriguing.
It’s highly corrosive and harmful to plants. While this can definitely be a good thing for controlling undesired vegetation, you can imagine what a problem it could pose to nearby plants or your lawn. That’s not to mention wildlife.
So, does bleach kill weeds?
Does Bleach Kill Weeds?
Yes - the short answer is that bleach definitely kills weeds. The question is, is bleach a GOOD weed killer? After all, it’s not just a matter of eradicating pesky weeds, but doing so in a manner that won’t compromise the health of nearby plants or our environment as a whole.
Is Bleach a Good Weed Killer?
When it comes to effectiveness against a variety of weeds, yes - bleach is a good weed killer. It will damage any plant it touches, whether you’re having trouble in your garden or need the best driveway weed killer.
Plus, bleach works incredibly quickly. We’ll talk more about how long for bleach to kill weeds later on, just know that visible results can be seen in mere hours. You probably have bleach in our house right now, too, saving you a trip to the store to find a more specialised weed killer.
But using bleach as a weed killer isn’t without its limitations. For one, it won’t kill the roots of the plant - which means you’re really only getting a temporary solution. Contact herbicides need repeated used for a complete kill.
More deep-rooted perennial weeds like dandelions and bindweed are somewhat resistant to bleach for this reason. Bleach as a weed killer won’t work well in set conditions either, as it will be washed away before it has a chance to work its magic on the plant’s foliage.
The Real Downside of Using Bleach to Kill Weed
The real reason we don’t recommend using bleach to kill weeds, though, is its impact on the environment. Sodium hypochlorite is notorious for altering soil pH and killing beneficial microorganisms.
In other words, it leaves your soil in a dire state. Anything you plant in the treated area will struggle to grow for a few seasons. Worse, bleach can run off into flower beds or lawns, damaging nearby plants.
There’s also a serious risk associated with bleach making its way into water sources. It can also harm pollinators and cause irritation to humans and pets if inhaled or touched.
So at the end of the day, does bleach kill weeds? Yes, but whether or not it’s worth it is something only you can decide. The truth is, there are far safer, gentler options at your disposal that can still decimate the most resilient weeds.
We’ll share some of our favorite alternatives to using bleach as a weed killer later on. But if you’re set on trying to concoct your own bleach weed killer recipe, we’ll share some tips below.
Bleach Weed Killer Recipe and Tips on Using Bleach to Kill Weeds
The best bleach weed killer recipe is actually the simplest one: 5-6% sodium hypochlorite. There’s no need to add anything else to the spray bottle.
In fact, trying to combine other ingredients - especially acid-based ingredients like vinegar - can be downright dangerous. Grab the essentials, put on some protective gloves and eyewear, and follow these directions for using bleach to kill weeds:
- Pour undiluted bleach into a spray bottle or watering can.
- Apply directly to weed leaves, ensuring complete coverage without excessive runoff.
- Let the bleach sit for 24 hours to dry out the plant.
- Remove dead weeds by hand, ensuring the roots are pulled up.
- Repeat as needed for stubborn regrowth.
There are a few tips we want to share on using bleach to kill weeds. First, save it for spot treatments only. Widespread application is going to wreak havoc on your soil and make it so nothing can grow in your yard. It’ll just end up looking desolate and barren.
As far as when to spray weed killer, follow typical best practices. A dry, non-windy day is best for minimising drift onto desired vegetation or runoff toward water sources. Try to spray when the plant is in its active growth stage so it takes up the bleach internally and fully dies.
If you’re applying the bleach to hard surfaces like patios, driveways, or walkways, take the time to rinse them off after the weeds have died to prevent long-term surface damage.
Of course, keep children and pets away, as you don’t want to stress about weed killer and dogs, cats, or little ones. This chemical can irritate the skin and eyes on contact. All that being said, how long does it take for weed killer to work?
How Long For Bleach to Kill Weeds?
There’s no one-size-fits-all answer for how long for bleach to kill weeds, as it depends on how vulnerable the weeds are. Some are more resilient than others. Your exact approach to using bleach to kill weeds plays a part as well.
In general, though, you should see the early signs of success within 24 hours - noticeable browning and wilting. Full desiccation may take 2-3 days depending on the weed’s size and resilience. Smaller, younger weeds die more easily than more established, deep-rooted species.
Better Alternatives to Using Bleach as a Weed Killer
So now you’re at a crossroads - you can try this bleach weed killer recipe, or you can keep reading for tips on how to kill weeds permanently without potentially harming other plants, the soil itself, wildlife, and our environment as a whole.
As we said earlier there are plenty of alternatives to using bleach as a weed killer that work just as well, if not better, while remaining gentle. Perhaps the best alternative to using bleach to kill weeds is our acetic acid-based weed killer at Jennychem.
Acetic Acid-Based Weed Killers
You’ve probably seen lots of UK gardeners rely on vinegar as a DIY weed-killing solution. It’s readily available, like bleach, and it works wonders. But the reason vinegar works is because of its acetic acid content!
This compound is a powerful natural herbicide that breaks down plant cells upon contact, drying out weeds from the inside out. But unlike bleach, it doesn’t linger in the soil. It’s non-toxic once it dries so you don’t have to worry about residual activity or harm to pets, kids, or other wildlife.
Just be aware that household vinegar likely won’t get the job done unless you’re fighting a very weak weed. Higher concentrations (above 20%) are needed. Try Weedex Super instead.
Whether you’re wondering how to get rid of ground elder naturally, what kills nettles permanently, or need the best weedkiller for ivy, Weedex works fast across even the most persistent weeds.
Thousands of UK gardeners trust it to keep their yard pristine, and you can too. Pair it with the right garden sprayers and you’ll be amazed at how easily you can control weeds!
Salt-Based Solutions
Salt has been used for centuries as a natural herbicide because it dehydrates plant cells and disrupts root systems. While our de icing salt is typically used to prevent slips and falls during winter, it can also help you keep weeds at bay.
It’s a great choice for gravel driveways, cracks in pavement, and non-planting areas. That’s because while it works great, it can sometimes make your soil infertile sort of like bleach does. We recommend applying one part salt, three parts water directly to weeds.
Boiling Water
Boiling water is another simple solution that doesn’t require a trip to the store or concern about lingering chemicals in your soil. It instantly destroys plant cells and kills growth on contact.
But do note that it can have the same effect on desired vegetation, so it might not be a good choice for the garden or lawns. Save it for pavement cracks, garden borders, and hard-to-reach areas.
You also need to know that boiling water won’t necessarily work its way to the roots, so regrowth is always going to be a risk with this approach.
Mulching
Mulching kills two birds with one stone: it prevents weeds from sprouting while enriching the soil for desirable plants. Mulch, be it wood chips, bark, straw, blocks out the sunlight and oxygen weeds need to thrive.
It’s a great choice for lawns, flower beds, vegetable gardens, and around trees. We recommend a roughly 5cm layer to suppress weed growth. You’ll enjoy better moisture retention and overall soil health as well!
Manual Removal
Last but not least, consider just rolling your sleeves up and doing things the old-fashioned way: pulling weeds out by hand. This is the best chemical-free method that leaves no trace behind in the soil, so you don’t have to worry about fertility issues down the road.
It’s obviously not practical for massive acreage, but will work well for spot-treating smaller infestations or gardens with delicate plants where chemicals are a no-go.
Use a weed puller or hand trowel to extract weeds at the root, noting that any root mass left behind will likely regrow into a new weed. Wait for the soil to be moist for easier removal.

So, does bleach kill weeds? In closing, using bleach to kill weeds may be effective on the surface, but bleach as a weed killer has its limitations. Not only does it leave roots intact, but kills all other life in your soil so nothing will be able to grow there for a while.
While it may work as a last-resort spot treatment, it’s far from the best option for long-term weed control. Acetic acid-based weed killers, salt treatments, or even manual removal are safer and more sustainable approaches.
