Can epsom salt be used as a weed killer?


Answer by  jdesroch (23)

Epsom salt will likely not kill your weeds. It may even help the weeds grow stronger, as the salts contain magnesium and sulfur. Magnesium is an element many weeds are missing, and epsom salts might rejuvinate weeds that would have been weaker. Sulfur, found naturally in the soil, will activate elements that will help the weeds, or plants, get stronger.

I don't think so I dont think it has the same internal make as table salt that would kill the weeds.

Yes it is a natural alternative to chemicals. You can use it to smother out areas but this requires a large amount of salt. It is better used in small spaces where the weeds are minimal and the other plants around it are not to be destroyed. It is always best to use sparingly.

Epsom salt can definitely be used as a weed killer and is especially good when used between the cracks in sidewalks. Mixing the epsom salts with hot water, and poured over the offending weed, will result in a clear sidewalk at the fraction of the cost of expensive store bought products that leave dangerous chemicals behind


Answer by  Opossum (29)

Salt can absolutely be used as a weed killer, but you probably don't want to do that. Salt is actually a *plant* killer, indiscriminately. So if you have, for example, weeds growing out of cracks in your sidewalk, you can use salt, but if you want to eliminate them from a flowerbed, try a different weed killer.
