How to Make Homemade Weed Killer<\/h2>
To prepare a homemade weed killer, you need the following:<\/p>
- Ingredients that actively damage plants,<\/strong> such as vinegar, lemon juice, salt, baking soda, rubbing alcohol, etc. <\/li>
- Water<\/strong> to ensure absorption when you\u2019re using a powder like salt or baking soda and, in some cases, to dilute the solution.<\/li>
- A surfactant<\/strong> like liquid dish soap. <\/li> <\/ul>
Weed leaves have a protective waxy layer that gathers sprayed liquids in well-defined droplets, reducing the contact surface. Surfactants lower surface tension, and the herbicide droplets spread wider across the weed, better covering the surface and killing more of the plant.<\/p>

Alcohols also have similar properties. Keep in mind that dish soaps are not <\/em>organic. Castile soap may be used as a natural alternative. <\/p>
DIY Weed Killer Ingredients and How They Work<\/h2>
Active ingredients used in homemade weed killers act as contact herbicides,<\/strong> only damaging what they touch. <\/strong>Since they only hurt top growth (leaves, stems) and not the root system, they work effectively on young annual weeds with small roots but are less effective on perennial weeds with extensive roots and vegetative systems.<\/p>
The efficiency of contact herbicides is highly dependent on coverage<\/strong>. Broadleaf weeds are more vulnerable than grassy weeds because it’s easier to get good coverage on their large leaves. <\/p>
Home remedy ingredients also make for non-selective killers,<\/strong> damaging everything they touch, friend and foe. <\/p>
Here are the main active ingredients you can use in homemade herbicides:<\/p>
Vinegar<\/h3>
How does this weed killer work? <\/strong>The active ingredient in vinegar, acetic acid, \u201cruptures plants cells, causing fluids to leak and plant tissues to dry out,\u201d says the University of Montana<\/a> on vinegar\u2019s effectiveness as a herbicide. Treated plants go yellow, then brown, then wilt and die within a day.<\/p>
Vinegar gets good results on broadleaf weeds<\/strong>, like dandelions, broadleaf plantain, or clover, where 10% to 20% acetic acid solution damages 90% of exposed plants. With grassy weeds, studies show a success rate of around 45% to 65%.<\/a> <\/p>
A study<\/a> published by the Cornell Cooperative Extension shows that acetic acid can also damage perennial<\/strong> quackgrass and Kentucky bluegrass<\/strong> upon application. But weeds resprout in about two months.<\/p>
Pro tip about <\/strong>using vinegar in DIY weed killer<\/strong><\/a> recipes: <\/strong>Look for horticultural vinegar with 20% to 30% acetic acid. Household vinegar has only 5% and is less powerful. <\/p>
Environmental Effect<\/h4>
Acetic acid breaks down easily, so any soil damage is short-lived. To keep the soil healthy and prevent damage to nearby plants, don\u2019t apply vinegar weed killer more often than once every two weeks.<\/p>
Safe Use<\/h4>
Vinegar with over 11% acetic acid can burn skin and permanently damage corneal tissue<\/strong> if it gets in your eyes. Wear gloves, long sleeves, long pants, and protective glasses to apply the solution safely.<\/p>
Acetic acid also damages metal, so avoid any metal fencing or garden furniture. Don\u2019t use a sprayer with metal elements to spread it (metal nozzle, metal spray lines, etc.). It can also stain and harm masonry surfaces.<\/p>
Lemon Juice<\/h3>
A natural weed killer<\/a>, lemon juice has 5% to 8% citric acid, another desiccant that dries weeds from the inside out. You can spray lemon juice directly on the weeds, but mixing it with vinegar improves results. See the recipe<\/a> in the next section. <\/p>
Environmental Effects<\/h4>
Typically, lemon juice is safe for your soil, except when used in large quantities. In this case, it lowers soil pH.<\/a> <\/p>
Safe Use<\/h4>
Lemon juice can irritate your eyes. Wear goggles, and don\u2019t spray when it\u2019s windy. Bear in mind that citric acid can damage marble, granite, and metal surfaces.<\/p>
Salt <\/h3>
Where it touches the plant, salt extracts water from the cells<\/strong>, and weeds dry from the inside out. <\/p>
It can also be absorbed through the roots<\/strong> if watered into the soil. In this case, salt disturbs the plant’s chemical processes, killing the entire weed. Used like this, salt damages the soil long-term, preventing<\/strong> any plant from developing. <\/p>
Remember that we are talking about ordinary table salt, sea salt, or rock salt rich in sodium chloride<\/strong>. Don’t use Epsom salt. It’s magnesium chloride, and you need sodium ions to damage the weeds. <\/p>
Environmental Effect<\/h4>
Warning!<\/strong> Excessive salt in the soil is toxic for all plants! Don\u2019t overdo it. <\/p>
Consider salt for spot-spray treatments only when you have a few young weeds to kill, <\/strong>so you\u2019ll use a small amount in just a few applications. The best applications are on on weeds in walkways, pathways, driveways, gravel paths, etc. <\/p>
Safe Use<\/h4>
Applying a salt herbicide is not generally risky for humans or pets. On the other hand, salt can damage porous materials like brick, concrete, sandstone, cement-based coatings, and metal.<\/p>
Dish Soap<\/h3>
While we primarily use dish soap as a surfactant in weed-killer recipes to help the solution stay longer on leaves, it also has some herbicide power. <\/p>
Dish soap breaks down oils and grease. When applied to leaves in a higher concentration, it destroys the protective waxy layer. It leaves leaves vulnerable to heat, dry air, diseases, and pests. Most soaps also contain perfumes, bleach, and other substances toxic to plants. <\/p>
Most dishwasher soaps are not <\/em>natural or organic, even though they’re included in many online lists of “natural” weed killers. <\/p>
Environmental Effect<\/h4>
Liquid soap pollutes soil and water. Avoid using it in large amounts.<\/p>
Safe Use<\/h4>
Dish soap can irritate your eyes. Spread with care and wear protective goggles.<\/p>
Rubbing Alcohol<\/h3>
At 5% concentration, rubbing alcohol or isopropyl slows down plant growth. At over 50%, it damages leaves and stems by dissolving their waxy layer and causing plants to lose water.<\/p>
Environmental Effect<\/h4>
Rubbing alcohol has a low tendency to sediment or bind to soil and is highly biodegradable. Still, large amounts of alcohol in the soil can destroy the microbiome and make the soil unsuitable for plants until it dissipates.<\/p>
Safe Use<\/h4>
Rubbing alcohol is harmful to pets and children if ingested. Keep it in a safe place. <\/p>
Wear a mask when applying, since it can cause irritation if inhaled. Alcohol can irritate the nose and throat. Prolonged skin contact can also lead to rashes and itchiness.<\/p>
6 Easy Homemade Weed Killer Recipes<\/h2>
![\"A](\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2023\/06\/Untitled-design-2-1.jpg\")
Photo Credit: AprylRED<\/a>\/ Canva Pro \/ License<\/a> <\/figcaption><\/figure> There are numerous homemade weed killer recipes available online, combining the ingredients we talked about in the previous section. Here are six homemade weed killer recipes you can use in your garden:<\/p>
Vinegar Weed Killer Solution<\/h3>
Make a vinegar solution by mixing 1 tablespoon of dish soap with 1 gallon of white vinegar (or apple cider vinegar) into a bucket or a canister. Stir thoroughly. Pour into a spray bottle and spot-spray the weeds in your garden. <\/p>
Use horticultural vinegar, not kitchen vinegar, if the weeds have more than 2 leaves or you\u2019re treating perennial weeds. <\/p>
Vinegar, Lemon Juice, Rubbing Alcohol, and Soap<\/h3>
Add 3 tbsp of lemon juice, 1 oz of rubbing alcohol, and 2 tbsp of liquid dish soap to 2 cups of vinegar in a spray bottle. Stir to homogenize, then spot-spray every weed. <\/p>
Salt Solution<\/h3>
Dissolve 1 cup of table salt into 2 cups of water. Put the liquid into a garden sprayer. Spread directly on the weed leaves, avoiding your grass and other valuable plants in your yard. <\/p>
Warning!<\/strong> Don’t overdo it! With salt, using too much and ending up with bare soil is easy. If you have perennials or stubborn annuals, try another mix without salt, or hand-pull the weeds and roots.<\/p>
Rubbing Alcohol Solution<\/h3>
Mix 2 tablespoons of rubbing alcohol with 4 cups of water and fill a sprayer. Apply on weed leaves and stems, avoiding plants you want to keep and the soil surface. <\/p>
Or, soak a cotton ball in alcohol and rub the weed leaves with it.<\/p>
Warning! <\/strong>Don\u2019t soak the soil with alcohol. Nothing will grow on it until you wash it off.<\/p>
Boiling Water<\/h3>
Put water into a kettle and heat it until it boils. Pour directly on the weed. The high heat ruptures plant cells and kills the vegetal tissue. <\/p>
Be careful not to get hot water on you. Wear long trousers and closed shoes (not sandals or slippers). Use an oven mitt if the handle is hot. <\/p>
Note:<\/strong> While boiling water that gets into the soil can kill some microbiomes, it\u2019s only a minor negative effect compared with salt and alcohol. <\/p>
Soapy Water<\/h3>
Add 1 cup of liquid dishwashing soap to 2 cups of water in a bucket. Fill a sprayer bottle and apply it on weed leaves, avoiding spills on the soil or plants you want to keep. <\/p>
Warning<\/strong>! Remember, dish soap is a water and soil pollutant. Use this recipe with moderation. <\/p>
How to Improve Results When Using DIY Weed Killers<\/h2>
Here are a few tips that give a boost to DIY weed killers and help you get better results:<\/p>
- Spread homemade weed killer when weeds are sprouting and only have 2, maximum 4 leaves. <\/li>
- Apply on sunny days when temperatures are over 80 – 85 degrees and rain is not forecasted for the next 2 to 3 days.<\/li>
- Spray the weed surface generously and thoroughly, doing your best to treat all the leaves and growing buds. <\/li>
- Add surfactants to homemade herbicide solutions. They help spread the solution better on leaves.<\/li>
- Repeat application if you\u2019re treating larger weeds.<\/li> <\/ul>
Pros and Cons of Homemade Weed Killers<\/h2>
Despite their increasing popularity, it’s wise to approach homemade herbicides with a grain of salt. They don\u2019t include the same harsh chemicals as most synthetic products, but some can still harm the soil if used extensively. Also, homeowners often have unrealistic expectations about their effectiveness. <\/p>
Before taking out the vinegar bottle or salt container from the pantry to prepare a DIY herbicide, consider both pros and cons of your idea. <\/p>
Pros of using homemade weed killers:<\/strong><\/p>
- Most are better for the soil than chemical herbicides<\/li>
- Many use organic ingredients <\/li>
- You probably already have most of the ingredients in your pantry<\/li>
- Even if you don’t, these ingredients are a lot cheaper than commercial herbicides<\/li> <\/ul>
Cons of using homemade weed killers:<\/strong><\/p>
- They are short-term burnout products, not long-term solutions. <\/li>
- These products work best with other weeding measures (hand pulling, keeping a dense and healthy lawn, etc). <\/li>
- There’s no selective DIY weed killer recipe so far.<\/li>
- DIY weed killers are less effective on perennial weeds since they’re not systemic and damage only the top growth.<\/li>
- More than a single application is required. <\/li>
- It can cost more than commercial solutions for extensive applications. <\/li>
- Some are toxic to the soil in large quantities.<\/li> <\/ul>
If you weigh the pros and cons and decide you’d rather use commercial herbicides than try your luck with homemade recipes, check out our recommendations for the best weed killers<\/a> you can buy (which include organic options safe for kids and pets).<\/p>
Other Ways to Suppress Weeds<\/h2>
![\"Huge](\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2023\/06\/weeds-935277_1280-1.jpg\")
Photo Credit: Pixabay<\/a><\/figcaption><\/figure> Weed control is a year-round activity. Applying a DIY herbicide to stop their momentum when the growing season starts is just a tiny part. For the best results, mix homemade weed killers with other weed management methods that:<\/p>
- Prevent weeds from developing healthy leaves.<\/li>
- Stop weed root development.<\/li>
- Physically remove grown weeds.<\/li>
- Prevent weed seeds from spreading from secondary areas.<\/li> <\/ul>
How to Prevent Weeds from Developing Healthy Leaves<\/h3>
You can keep flower beds and vegetable plots free of garden weeds<\/strong> by using these weed control methods:<\/p>
- Apply a layer of mulch<\/a><\/strong>, 2 – 3 inches thick. It stops sunlight from reaching the soil, and weed seedlings can’t develop.<\/li>
- Plant a ground cover<\/a><\/strong> that is also a good companion for your flowers or vegetables. It leaves less space and nutrients for weeds.<\/li>
- Install a layer of landscaping fabric<\/strong><\/a> to prevent weeds from emerging.<\/li>
- Grow the plants denser<\/strong> if this doesn’t affect their health, development, and productivity.<\/li> <\/ul>
To keep the weeds out of your turfgrass:<\/strong><\/p>
- Maintain healthy, thick grass<\/strong> that leaves no space for weed seeds to reach the soil or weeds to grow.<\/li>
- Mow correctly<\/strong>, leaving the grass a little taller during the growing season.<\/li>
- Irrigate deeply and less frequently<\/strong> to promote robust turfgrass, resilient to stress and diseases.<\/li>
- Fertilize properly <\/strong>to prevent excess nutrients in the soil.<\/li>
- Overseed in spring and fall <\/strong>if you notice thinning or bare spots.<\/li> <\/ul>
Stop Weed Sprouts from Rooting with Corn Gluten Meal<\/h3>
A residue of milling corn, corn gluten meal<\/a> is often used as a fertilizer because it’s rich in nitrogen. It also works as an organic and environmentally safe herbicide when used at a specific time in the weeds’ life cycle. <\/strong><\/p>
The peptides present in corn gluten stop sprouts from developing roots<\/strong>. Corn gluten doesn’t prevent germination and is useless once the plant has formed roots. But applying it during the sprouting period can yield excellent results.<\/p>
Corn gluten is a granular substance and requires watering to become active. But it will need a few dry days after that to successfully desiccate the young weeds’ forming roots.<\/p>
Hand-Pull Weeds in Lawns, Flower Beds, and Vegetable Plots<\/h3>
While weeds are still sparse in your garden, you can get rid of them by hand-pulling. It becomes more challenging when there is a large number of weeds. <\/p>
The perfect moment to remove weeds by hand or with a hand weeder is after a good rain. If it’s a dry period, irrigate thoroughly the night before to loosen the soil. Roots will come out easier. <\/p>
Pro tip about hand-pulling weeds:<\/strong> Know your weeds<\/a>. This is a good method to attack perennials like crabgrass and Kentucky bluegrass. Use a screwdriver or a hand weeder to dig around perennials. Look for more roots, rhizomes, and tubers they might use to resprout. <\/p>
Burn the Weeds on Walkways and Driveways <\/h3>
Mainly a wand connected with a propane container, a propane torch can be used to remove weeds with fire. It’s excellent for eliminating weeds in pavement cracks, gravel surfaces, and patios. Avoid using it in flower beds or lawns. You risk damaging flowers and grass. <\/p>
There’s no need to get the flame on every leaf. Only the high heat is enough to damage the plant. You can buy such a tool at your local garden shop or home improvement store or online.<\/p>
Warning! <\/strong>Always practice fire safety when using a propane torch. Turn the flame on only for a moment, just long enough to burn the weed. Do not use a propane torch near lots of vegetation or during a drought. <\/p>
FAQ About Homemade Weed Killers<\/h2>
What is the Strongest Homemade Weed Killer?<\/strong>The strongest homemade weed killer that breaks down easily and doesn\u2019t damage the soil is a mix of vinegar with 30% acetic acid and liquid soap as a surfactant.<\/p> <\/div>
What Kills Weeds Down to the Root?<\/strong>Homemade products are contact herbicides and don’t usually damage the root system. Salt can kill the entire plant when watered into the soil, but it also contaminates the ground so severely that nothing will grow on it for a long time.\u00a0
Can Clove Oil Kill Weeds?<\/strong>Some essential oils like clove oil, peppermint oil, and orange oil can damage weeds. They are contact herbicides that attack only the surface they touch. Essential oils are typically used in a mix with more potent herbicides such as vinegar, and they don’t do much on their own.<\/p> <\/div> <\/div>
