Make an herbicide potion, learn how to uproot weeds that grow in cracks, and find out how to get rid of poison ivy with our best homemade weed control tips.

Spray weeds with salt

An inexpensive ingredient already found in the home could be a great gardening ally! Salt will kill many of the weeds that cannot be completely uprooted. Use a pitchfork to remove the soil at the base of the roots and then cut the stem as close to the ground as possible. Pour salt over the cut, trying not to spill it around.

Remove weeds from cracks with vinegar and salt

If weeds or grass are growing in cracks in your driveway, sidewalk or other paved area, spray them with a solution of salt and vinegar. Mix 460 mL (2 cups) of vinegar, 60 mL (¼ cup) of salt and 2 drops of dishwashing liquid in a jar, then close the lid tightly and mix well. Another simpler solution is to pour boiling salted water into the cracks. In either case, make sure the liquid does not touch your plants.

A homemade herbicide to kill weeds

It’s true that herbicides are effective, but there are also environmentally friendly solutions to consider that are easy to prepare at home. Regardless of your views on green or conventional gardening, it’s always wise to try low-toxicity herbicides before moving on to powerful poisons.


The acetic acid in vinegar kills the leaves of weeds, not their roots. However, if you spray the weed often enough, this method will deplete the weed’s energy reserves and eventually kill it.

  • 460 mL (2 cups) of water
  • 345 mL (1½ cups) vinegar (white or cider)
  • 115 mL (½ cup) dishwashing liquid

Using a funnel, pour all the ingredients into a one-litre spray bottle. Shake well to mix. Spray the solution directly on the weeds (avoid spraying on your plants).

Make a poison ivy cocktail

No one wants to mess with poison ivy. Looking for a simple way to get rid of it? Water and vodka will do the trick. Mix 460 mL (2 cups) of water and 2 tablespoons of vodka in a spray bottle. The dehydrating effect of the vodka will kill the plant soon after its leaves are saturated with the mixture.

Newspaper to keep weeds down

If an area of your garden is overrun with weeds, try one of these mulches to keep weeds down.

Wet several pages of newspaper so that they stick together, then lay this mat over a patch of weeds. Camouflage it with wood chips or other mulch. You can remove it when the weeds are gone.

Plastic covers to keep weeds down

Cut black plastic garbage bags along the seam to double the size and cover the problem area of the garden with them. Camouflage with shavings or other material and leave in place for 10 to 14 days. Weeds should not survive this treatment.

Basil to spice up your crop

Take advantage of essential oils to treat weeds in a gentle way. Thanks to the weed-killing and fungicidal properties of basil essential oil, you’ll get rid of weeds in no time.

Mix basil essential oil with your homemade herbicide soap and spray it at the base of the weed. The little weed won’t be able to resist this sneaky treatment for long.

Regular weeding to eliminate weeds

To effectively eliminate weeds from your garden, arm yourself with patience, discipline and… get to work! The more often you weed, the less difficult and time consuming the task will be.

Using the right tools will also help you weed your garden quickly. The weeder, equipped with a fixed or oscillating blade, allows you to cut the seedlings at their base. The hoe can be used to uproot weeds that have had time to grow.

Recycling Grass as a Weed Control Treatment

When you cut your grass, instead of picking it up and bagging it, save it. Cover the weeds with freshly cut grass to smother the plant and kill it. However, if your lawn has a lot of weeds, avoid this treatment. You may spread the weeds more than you kill them.

Control to control

Even if your herbicide is organic or you make it yourself at home, there’s still a risk of killing other plants if you pour it on. To use herbicide effectively, simply use an inverted funnel to focus the spray on the weed, not on your desirable or edible plantings.

To do this, take a two-liter container of cola and cut off the bottom of the bottle to remove it. Take the cut bottle and put it over the weed. Open the cap, insert the nozzle of your herbicide sprayer and spray generously. Once the treatment is complete, remove the funnel and move on to the next plant. Your plantings will be spared and the weeds eliminated.

The right plants for weeds

Some plants, when they grow, produce a large quantity of foliage on the ground. This abundant and dense foliage occupies the entire growing space and prevents the weed from taking its place among the good ones.

Mustard, clover and phacelia are plants that are called green manure. Buckwheat is also a green manure. Ask a specialist to choose the one that suits you best.

The weeds have gone up in smoke!

You can also simply burn the weed to prevent its proliferation. With a small torch or a blowtorch, apply heat to the controlled area where you want to control the weeds. But be careful: it is very important to first make sure that the operation is safe and under control. Make sure you have the necessary equipment to put out a fire and do not do this treatment when the weather is dry, in extreme heat, or if you are near a forest or flammable materials.

Baking soda is the real killer of weeds.

To deal a fatal blow to stubborn weeds, use baking soda, commonly known as “the little cow. Simply pour a generous amount of baking soda into the gaps in your stone patio, for example. Then, sprinkle with water or simply wait for rain. The combination of baking soda and water will slow down the growth of weeds.

A Simple and Affordable Way to Get Rid of Weeds: Hot Water

A simple solution to weed control is to use very hot water. Boil some water and pour it over the weeds immediately. This will kill them instantly. It’s that simple!

You may have to repeat this a few times over the summer, but it’s definitely the easiest way to get rid of weeds in your garden.

Fool the weeds with false seedlings

If you want to improve your chances of having weed-free soil, practice false seeding. This is basically preparing the soil, as you would if you were ready to plant, 2 to 3 weeks before your crop is planted.

In this moist, aerated soil, weeds will emerge without delay and you can weed them out afterwards. Repeat this gardening trick once or twice, then start your crop in earnest.

Lime for the gardener

Lime is primarily used as a fertilizer for your lawn. By pouring lime on your lawn, it will be nourished and healthy.

After a few years of lime treatment, moss and weeds will be gone from your garden for a long time.

Mulching the soil to control weeds

Mulching is a very effective technique to prevent weeds from growing.

Mulching consists of spreading organic matter residues on the soil of a crop. The residues can be grass clippings, dead leaves, wood mulch, wood scraps, bark chips, etc.

In addition to smothering the soil and controlling weeds, mulching allows the soil to retain water and reduce natural evaporation.
