Table Salt – Using salt to kill weeds is a common do-it-yourself solution. When salt is absorbed by plant root systems, it disrupts the water balance and causes the weed to eventually wilt and die. But salt by itself doesn’t make a very effective weed killer.
How do you stop weeds growing through block paving?

Is salt or vinegar better for killing weeds?

What happens if you put salt on the ground?
Salts in the soil can absorb water. This results in less water being available for uptake by the plants, increasing water stress and root dehydration. This is referred to as physiological drought, which, if not corrected, can lead to reduced plant growth.
How fast does salt and vinegar kill weeds?
Vinegar kills weeds quickly—usually within 24 hours—but does not discriminate between the weeds you want to kill and the plants you want to grow, so apply the vinegar carefully and in the right conditions. Vinegar’s efficacy depends on the weather and the solution’s concentration.

A major problem with using rock salt even in small concentrations is that is tends to stay in the soil for years until water leaches it out. The salt raises soil salinity, which dehydrates the roots of plants and keeps them from absorbing necessary nutrients.
When should I throw salt off my driveway?
The best time to treat the ground is before snowfall begins. Treating areas before snow (and freezing rain/ice) begins can help prevent ice from forming and prevent snow from settling. Because salt has a lower freezing point than water, it reduces the opportunities for moisture to freeze on treated surfaces.
Does salt destroy your driveway?

What is the best salt for driveway?
Magnesium chloride is a great choice! While magnesium chloride is more expensive than sodium chloride and calcium chloride, it is less likely to damage your concrete or your lawn. This type of salt only works in temperatures down to 0° F, which is better than sodium chloride but not quite as good as calcium chloride.
How much salt do I need to prevent weeds?
Sprinkle a few chunks of rock salt on the soil surface at the bases of weeds. They’ll begin dying from desiccation within several days. Use salt sparingly, and don’t count on anything growing there or in the area immediately surrounding it for years to come.
