The timeline for salt to effectively kill weeds can vary significantly, influenced by several key factors that impact the speed of desiccation. Typically, you can expect to see results within a few days to a couple of weeks after application, but understanding the variables at play will help set realistic expectations.
To use salt as weed killer, pour salt on the weeds/area/sidewalk seam or crack. Water it to dissolve the salt and allow it to soak into the soil and attack the roots of the weeds. The weeds should start to wither and die in a few days.
You can kill many weeds with vinegar. Heat (blowtorch, or specialized weed killing torches using flame or steam), roundup (glyphosate), weed block fabric, or even cardboard/newspaper Will work, too.

The primary difference between rock salt and ordinary table salt is the size and colour. Rock salt forms in very large, chunky crystals, as opposed to the small crystals seen in table salt. Like table salt, rock salt also has an assortment of trace minerals which can have an impact on how it behaves chemically.
A few wayward chunks of rock salt won't harm your lawn. Large amounts can stay in the soil for years, though, accumulating every year until the salt creates an environment toxic to your grass. Salt stays there until it's leached away by rainwater, which means you won't be able to plant new grass until the salt is gone.
This is a good place to start when controlling weeds in your garden. You can increase the concentration for stubborn weeds, but only when using it on pavement or driveways, away from fertile soil. Some recipes recommend a water-to-salt ratio of 3:1 or 2:1, meaning four cups of salt or more per gallon of water.
In short, salt is an effective non-toxic herbicide. However, not all salt is created equal when it comes to weed control. Regular iodized or non-iodized table salt must be used. Check the package to ensure you are using sodium chloride, not magnesium sulfate (Epsom salts), rock salt, or sea salt.
Baking soda makes an incredible weed killer especially when it is mixed with other kitchen staples, like vinegar or lemon juice. Just dissolve 1 ½ cup of baking soda and a tablespoon or two of vinegar in a gallon of water. Transfer the concoction in a spray bottle and spritz away!
When applied to driveways and sidewalks and used in lawn care, rock salt dehydrates or pulls out moisture. It works well as a deicing agent, and it's also commonly used as a natural weed killer. When applied to soil and grass, the salt removes both moisture and nutrients.
Salt disrupts how a plant can use nutrients to grow and thrive. The sodium ions prevent the flow of potassium and magnesium through the tree's root system. These nutrients are necessary ingredients in the making of chlorophyll, and when a tree can't make the chlorophyll it needs for food, it will die.
Bleach will kill weeds because it's toxic to all living things. It's formulated to kill germs and algae, so it has no problem killing your pesky dandelions, crabgrass, and bindweed. If you spray diluted bleach on a weed, the liquid will soak into the soil and kill the plant, roots and all.
Sodium may damage roots through direct toxicity and kill sensitive plants. High levels of sodium can destroy the aggregate structure of fine- and medium-textured soils. This decreases porosity and prevents soil from holding sufficient air and water needed for plant growth.
Extreme dehydration
The dehydrating effect of rock salt will dehydrate ice just as easily as it will dehydrate your grass. When rock salt comes into contact with plants, they become brittle and begins to wilt and die.
It is harmful to plants because salt absorbs water, thus pulling water away from the roots and out of the plant's tissues. Moreover, as the salt dissolves in the water, it splits into sodium ions and chloride ions – which affect the plant in different ways.
Though seemingly harmless to us, rock salt can have corrosive effects in large quantities that affects cars, trucks, bridges, and roads resulting in approximately $5 billion dollars in annual repairs in the U.S. alone.
Sea salt is a general term for salt produced by evaporation of ocean water or water from saltwater lakes. It is less processed than table salt and retains trace minerals. These minerals add flavor and color. Sea salt is available as fine grains or crystals.
Aman Puri, Founder and Nutritionist, Steadfast Nutrition, said, “One teaspoon of table salt provides 2.3 g of sodium, whereas one teaspoon of rock salt provides 1.9 g of sodium. Rock salt is a healthy alternative to common salt as it contains more minerals (potassium, calcium, magnesium, iron, and manganese).
Weed Killer for Areas Never to Grow Again
Mix two cups of ordinary table salt with one gallon of white vinegar to kill all vegetation in walkways, driveways, and other areas where you don't want any living thing to grow again.
Some landscapers swear by periodically sprinkling salt over the area. Apply the salt liberally and spray the area down with water. You can also use a preemergent weed killer, as long as you apply it carefully, in accordance with the manufacturer's instructions.
