Additionally, weeds are prevented and hazardous weed killers aren’t needed thanks to landscaping bio-degradable fabric. Y

ou’ll learn how to create powerful, natural weedkillers that will keep your garden thriving in this article. These natural weedkillers are safe to use and effective, and many of them are pet-friendly alternatives to chemicals such as roundup.

Why Use Homemade Weed Killers?

In place of using chemicals on your lawn, flower beds, or vegetable garden, natural weed killers are an option. To minimize the environmental consequence of pesticides and herbicides, many gardeners choose to utilize natural elements in home-made goods. Homemade weed killers aren’t dangerous to children or pets, in addition to the environmental damage that commercial weed killers may cause.

They don’t contaminate the food chain, either. A alternative to products containing pesticides like glyphosate, which is utilized in Roundup, is organic DIY herbicides. Selective herbicides like 2,4-Dichlorophenoxyacetic acid (2,4-D) may be replaced by natural weed killers for pre- and postemergent weed management. Many individuals choose to eliminate weeds by going the natural route, despite the fact that these chemicals are deemed “safe for use.”

Homemade Weed Killers vs. Roundup

Roundup, which contains glyphosate, is a common weed killer. This is a weed-control product that kills the whole plant, including the roots. It will kill anything that comes into touch with it, whether it is a weed or not. You may utilize glyphosate to manage perennial weeds since it kills the whole plant. Because roundup will travel to areas of the plant that were not sprayed, coverage is less important when using it.

The environmental impact of products like Roundup is a source of concern. Glyphosate, for example, has been shown to harm honeybee colonies in several studies. Other research has shown that even when used inside authorized toxicity limits, the chemical is still harmful to people.

The use of substitutes for hazardous substances makes sense to many individuals. Are they as effective as Roundup in the fight against weeds? DIY natural weed killers are often sold as a natural replacement. DIY natural weed killer sprays and Roundup are not systematic, which is the only difference.

This implies that the plant will not be killed completely. Unless they are combined with salt, natural weedkillers will generally preserve the root. While being used as a weed killer, salt has its own downsides. You’ll need to reapply the natural weedkiller every year after spraying perennial weeds because they may regrow.

Many weeds may be killed on contact by a homemade mixture of vinegar and salt. Salts in the soil can be prevented from accumulating with modest doses. Also, alongside other natural weed management tactics, homemade vinegar weed sprays may help kill weeds.

Natural Weed Killers

For lawns, vegetable gardens, backyards, and flower beds, here’s how to make natural weed killer sprays.

Use Vinegar as Natural Homemade Weed Killer

Vinegar, which has acetic acid, may be utilized in home organic weed killer formulas. To help it stick to surfaces and kill plant matter, vinegar must be combined with dish soap like Dawn. This natural weedkiller works better with added salt, but it must be applied correctly.

Vinegar may be an effective substitute for glyphosate (Roundup), according to a research by the University of Maryland. Young weeds were killed by vinegar that contained 5% to 10% acetic acid. Crabgrass and broadleaf weeds were controlled by using 20% acetic acid in commercial vinegar.

Vinegar (acetic acid) has been used to control chickweed, ground ivy, pale smartweed, tumble pigweed, velvetleaf, and carpetweed according to other research. It’s critical to keep in mind that vinegar is very acidic when utilized at higher concentrations. You must, however, handle vinegar with caution since it is a natural and environmentally friendly weed killer.

Natural Weed Killer Using Vinegar, Salt and Dish Soap

Homemade weed killers that kill everything are easy to make. Vinegar, dish soap, and salt are all you need. To naturally kill weeds, spray this solution on unwanted plants. You’ll need to understand how the ingredients work together to comprehend why this spray might be a safe substitute to Roundup and other artificial herbicides.

Vinegar— When a plant comes into touch with acetic acid in vinegar, it dies. You can help to zap weeds for good by using 5%, 10%, or 20% acetic acid concentrations. You can use this natural product for weed control, but certain weeds may need multiple applications.

Dish soap— Dawn dish soap, for example, functions as a surfactant that allows vinegar to be spread onto weeds’ foliage. The vinegar in this homemade weed spray is able to penetrate more easily and work more effectively if a few drops of dish soap are added.

Salt— When applied to leaves, inexpensive table salt (sodium chloride) is harmful to plants and also kills them through root absorption. Salt has the disadvantage of making soil unproductive, thus no plants can grow. If you’re dealing with driveways, walkways, or any place where no plant or grass should grow, then only add salt to the formula.

Recipe to make natural weed killer spray using vinegar, dish soap, and salt

The following ingredients are required for this homemade herbicide spray:

  • Half a gallon (2 l) of vinegar, preferably with a high acetic acid content.
  • 1 cup of liquid dish soap (Dawn or any other brand).
  • (only if you don’t want any plants or grass to flourish there) Half a cup of salt.

Mix all of the ingredients in a big container until they are fully blended to make the natural herbicide. Spray the weeds with the liquid directly from a spray bottle until they are saturated. Leave out the salt when you’re planning to plant anything in that area of your yard. Soil may become unproductive if salt builds up. Vinaigrette, on the other hand, will only destroy your weeds without harming the soil.

Use Boiling Water or Steam as an Eco-Friendly Weed Killer for Driveways

Weeding can be done effectively with boiling water, without causing any harm to the environment. Plants growing through pavement, edges, or driveways are destroyed by water at 212°F (100°C). Just bring water to a boil in a kettle, then pour it on troublesome weeds.

Using a steam cleaner to kill weeds is another kind of thermal weed control. Any weeds spoiling the look of your yard, walkway, or driveway will be quickly killed by the hot steam. Of course, take necessary steps to avoid burns when utilizing boiling water or scorching steam. A tablespoon of table salt to two quarts (2 l) of boiling water makes marijuana control even more effective.

Natural Weed Control with Borax

Some types of weeds in your garden may be killed by a natural weed killer spray made with borax and water. Borax has a weed-killing property that is sodium borate, which is a natural substance. Ground ivy (Glechoma hederacea) may be controlled using eco-friendly weed killer sprays. There are a few things to remember before using borax for post-emergent weed control:

  • Borax, while being natural, is harmful to cats and dogs. As a result, borax isn’t considered a safe pet weed killer.
  • Borax is only effective on a small number of plants as a homemade weed killer.
  • Beneficial plants and turfgrass will be killed by a borax weed killer spray.

How to make a natural weed killer (herbicide) spray with borax

Here’s the borax spray recipe for getting rid of ground ivy:

  • Borax is mixed with 2 fl. oz. (85 g) Mix until dissolved in a mixture of 1 oz. (60 ml) warm water.
  • Add 1 gallon (4 litres) of water to the borax solution and mix thoroughly.
  • Transfer the weed killer from a bottle into a sprayer.
  • Spray the weeds you want to eliminate directly.

Salt is a Safe Way to Get Rid of Weeds

Salt is a naturally occurring substance that may additionally eliminate weeds. The greatest benefit of using salt to kill weeds is also the greatest disadvantage. Plants, not just weeds, are permanently killed by salt. Nothing will ever grow in that area again if there is too much salt in the soil.

If you don’t use salt carefully, it may have an environmental impact. If there is too much rainwater in the soil, it might allow salt to seep into the roots of nearby plants. However, as a non-toxic, pet-safe method of weed removal, salt has limited usefulness.

For instance, you may use salt and boiling water to clean up sections of your garden that you don’t want to develop. In cracks in your driveway, between decorative bricks in walkways, or other places where you want to exterminate plants for good, pour a salt solution.

Other Safe, Environmentally Friendly Weed Killers

Preventing weeds from growing rather than treating your yard with homemade weed killers, is much simpler. To make your yard a garden to be proud of, many eco-friendly weed control methods will also enhance its beauty.

Bio-degradable Landscape Fabric

Weeds are prevented from growing and sprouting due to the landscape fabric. Weed-control barriers made of linen or wool, for example, are both environmentally friendly and biodegradable. As a result, you can breathe easier knowing that it has minimal environmental consequences.

Unsightly annual and perennial weeds may be kept at bay using a weed fabric in combination with mulch. When growing perennial garden plants, this method of weed control is best. Landscape fabric will save you time and effort in your yard, not only reducing the quantity of weed killer spray you have to apply, but also eliminating it.


Mulch is a weed management technique that doesn’t use weed killers and is one of the best. Organic mulch, such as bark chips or wood shavings, helps to protect the soil from erosion. Mulch helps to suppress vegetation by blocking out light. To improve the look of landscape trees, you can also mulch around them.

Mulch also improves soil health and protects plants throughout the winter. Organic mulch, for example, decomposes and distributes nutrients into the soil at a rate of about 1 inch per year. Mulching also helps keep moisture from escaping on hot summer days. In the winter, mulch serves as a cover for perennial plants and keeps them safe from temperatures.


Hand digging out some varieties of stubborn weeds, such as dandelions, dock, and other taproot weeds, is a good strategy. You’ll permanently get rid of bothersome weeds by rooting them out. Of course, maintaining a weed-free garden landscape requires some effort, but the reward is watching your plants grow.

thoroughly water the region of garden or lawn where you want to eliminate weeds before you begin weeding. Working and digging in the wet soil is simpler. Then gently remove the weed from the ground, taking care not to damage the roots, by digging around it. Make sure to dig out any roots that break off; otherwise the weed will come back.


To help keep weeds at bay and prevent them from sprouting, create a physical barrier. Weed roots are kept from spreading underground by wood, stone, or recycled plastic edging that is at least 6″ (15 cm) deep. It also helps prevent weeds from spilling over the top if the edging is a few inches above ground.

Another advantage of edge gardening is that it reduces weed growth. To enhance the appearance of your garden, use edging along flower beds, along pathways, or to separate sections. You have more time to enjoy your garden landscape because edging eliminates the need for weeding.

Ground cover plants

One of the most environmentally friendly techniques to keep weeds at bay is to plant ground cover plants. There are groundcover plants for shaded areas, as well as many creeping ground plants that thrive in full sun. Weeds can’t sprout and grow because of perennial ground covers, which block light.

Ground cover plants are low-maintenance, which is another advantage of them for eliminating weeds permanently. As a result, you get stunning blooming plants that require no maintenance and spread a veil of color.

Let lawn grass grow taller

To deter crabgrass, dandelions, and other types of bothersome weeds from developing in your beautiful green lawn, let grass grow taller. Irritating weeds will flourish if you mow your grass too short, which will detract from the look of your lawn. You’ll only encourage weeds if you want your lawn to appear like a golf course green.

The height at which grass grows best varies depending on the kind of grass. It might be any length between 1 and 3 inches (2.5 and 7.5 cm). For mowing techniques to be effective for controlling weeds naturally, you may also have to physically remove dandelions or crabgrass.

Plant robust plants densely

The survival of the fittest is at the heart of a garden landscape. The best method of getting rid of weeds in a non-toxic and natural manner is to grow robust, hardy plants. To discourage weeds from growing, bushy plants may shade out light. Alternatively, avoid allowing weeds to grow by using thick planting methods.


Killing off weeds with newspapers or cardboard is an environmentally friendly method. As a DIY weed killer technique, you may put a layer of newspaper on low-growing weeds such as crabgrass or clover. The newspaper is made of natural materials and will eliminate light over time, eventually killing the weeds.

As a safe and environmentally friendly landscape fabric, you can use newspaper or cardboard. Just remember to utilize black and white newspapers, not any colors. With cardboard, the situation is similar. Chemicals shouldn’t be used to treat cardboard.

Corn gluten meal as a non-toxic pre-emergent weed killer

To keep weeds from growing and spoiling the look of your lawn, use corn gluten meal. Weed seeds cannot root after they’ve germinated because of corn gluten. Corn gluten meal may help you keep crabgrass at bay by using it correctly. Corn gluten contains nitrogen, which is another advantage. To promote healthy growth, this beneficial nutrient feeds your lawn.

Homemade Weed Killers: A Takeaway

Gardening with organic weed killers requires that you know how to produce and utilize homemade, natural weed killers. Weed killers that are safe, non-toxic, and eco-friendly eliminate the need for using hazardous chemicals. Moreover, the number of weeds in your yard can be greatly reduced by using environmentally friendly weed control strategies.
