Using salt water to kill weeds in the garden?

Answer 1

Salt kills any plant by causing water to move out of their root cells instead of in. This causes cells to die, and if enough are damaged, the whole plant will too. It makes them appear 'burnt' in much the same way as too much fertilizer will.

Answer 2

Salt will kill any plant, including weeds. In moderation, its also a fertilizer. If you increase the salinity or salt content of the soil to a point of where its too high, the plant will use all of its water to get rid of the extra salt that it gets from the soil and will die of dehydration. The same thing will happen if you or I drink sea water. I use vinegar as a weed killer.

Answer 3

AnswerSalt is often used to kill weeds because it absorbs water. In other words, the plants die of thirst

Many of the active constituents in herbicides are present in the form of isopropylamine salt, such as ROUNDUP which is best bought in the concentrate 360g/L GLYPHOSATE. a good question is what is the other stuff, many people suggest the other stuff is worse for the environment and better for killing weeds than the glyphosate.

Answer 4

Yes, salt kills weeds.

Specifically, it is considered an effective, natural way of controlling weeds. One advantage is that it is not a chemical pollutant. But one disadvantage is that - depending upon the concentration - it kills everything else in the area.

Historically, the ancient Romans used to salt the lands of those they conquered and wished to punish. That is what they did to the lands of their arch enemy, Carthage. In fact, they so heavily salted the lands that nothing would grow. It was the complete and immediate destruction of a way of life.

Answer 5

Yes, saltwater will kill weeds if the plants in question are not saline-tolerant. As a non-specific, non-target control on aquatic or freshwater plants, it will be an effective treatment depending upon the potency and quantity even though it also may damage desirable plants.

Answer 6

Yes, saltwater kills weeds if the plants in question are not saline-tolerant. Saltwater, as a non-specific, non-target control, may be an effective treatment on brackish-, fresh- or salt-water-loving plants. The results nevertheless will depend upon the potency and quantity even though the treatment also will have the potential of damaging desirable plants in the area.

Answer 7

too much salt in the soil prevents the plant from gaining water through its roots, that said salt is NOT a good weed killer

Answer 8

Salt will kill most vegetation when applied to the soil but it will remain in the soil and kill any crops planted.
