Will salt prevent weeds from growing

Spread a thin layer of rock salt between your walkway’s bricks, pavers or stones. It will kill any weeds or grass growing there, and keep them away for years.

Invite butterflies to “puddle” in your garden with rock salt. Groups of butterflies often cluster on wet mud or sand to consume soil minerals. Combine 1 cup of rock salt with 1 gallon of coarse sand. Fill a shallow container with the mixture and embed it in the garden soil. Keep the mixture moist to attract butterflies and encourage puddling. The best spot for your puddle is near a drip or soaker hose, where it will always be wet.

Step 2:

Rock salt doesn’t discriminate between weeds and other plants — it kills them all, and they’ll never come back. If you’re interested in improving soil condition, don’t apply any rock salt to the area. Salt serves to weaken the integrity of the soil, and may damage it permanently. The only antidote is to remove the tainted dirt and replace it with new soil, and even that may not restore the area.

Apply rock salt to cracks and crevices in your pavement or driveway. Spread it over gravel walks and drives. It will remain active and prevent re-infestation for quite some time.

Things You’ll Need

Salt has been used to kill weeds since the early days of ancient Rome. The ancient city of Carthage and its agriculture were destroyed by the Romans, who some believe sowed rock salt into the territory’s croplands following the fatal siege of the last Punic war. Rock salt and table salt are both made of sodium chloride. Table salt is finely ground, purified rock salt. Rock salt has a gray tint because it’s unrefined, rendering its large, coarse crystals unsuitable for table use. The chunky crystals make it less expensive and easier to use for highly effective and economical organic home weed control. This is a permanent solution for areas you never want anything else to grow in again.

That being said, there are some non-toxic herbicides that can be used to effectively control weeds in the garden—namely, table salt. While no herbicide can ever be labeled as truly ‘harmless’ in the garden (their main purpose is to kill unwanted plants after all!), salt (or sodium chloride) is a natural solution that works well on pesky weeds.

Learn how to use household table salt to kill stubborn weeds.

Dealing with weeds in the garden is a task that most gardeners have come to dread. Pulling them by hand is time-consuming and repetitive, but many gardeners also want to avoid using commercially available chemical herbicides as they pose both environmental and health risks.

Can Salt be Used to Kill Weeds?

Salt (sodium chloride) works to kill weeds by dehydrating the plants and disrupting the internal water balance of the plant's cells. Since salt is water-soluble, it is most effectively applied when mixed with water as this makes it easier for the weeds to absorb. Sodium chloride is highly toxic to all plants, which is why caution must be taken in its application. In general, salt is best used as a herbicide for small-scale gardening or weed control.

Solid rock salt application

Of all those disadvantages and precautions of using salt to control weeds in gardens, yards and patios, I concluded that you have to choose the right places to kill weeds with salt.

Vinegar is a highly effective organic herbicide. When coupled with salt, it makes a highly potent weed killer. The solution can control weeds permanently when applied.

Liquid salt solution application

Salt works by dehydrating plants and disrupting the water balance of plant cells. As the weed loses water, it starts to wilt and die off permanently. This organic weed killer prevents new weeds from growing where it is applied. You can use rock salt or even table salt to get rid of weeds and grass in unwanted areas.

Applying too much salt on weeds will kill them permanently due to sodium chloride toxicity. You can apply rock salt or a highly concentrated salt solution directly on the weeds to get rid of them in about 10 days. Use salt to control weeds in driveways, walkways, patios, pavements, gravel, and rocky areas.

How long does it take for salt to kill weeds

As you’ve seen, salt works well as a water soluble weed killer. It is effective and can knock out weeds in rocky gardens, paveways, patios and even in gardens.

This way, the salt will gradually leach into the ground and prevent anything from germinating for years to come. This makes it a great for killing grassy weeds that keep growing in driveways and pavements.
