Will Pool Salt Kill Weeds Naturally? – DIY GUIDE

Spread the love

I would not suggest you use salt to kill any vegetation. It will kill weeds or whatever you want it to but the salt will descend into the soil and stay there for many years and NOTHING will grow in that spot/area for years.

A much better alternative is Round-up (and the cheaper knock-offs available). This is a much more effective solution and, most importantly, leaves no residual in the soil. You can plant your seeds or vegetation where you sprayed in a few days’ time.

Secondly, salt will move horizontally when heavy run occurs and perhaps move into area you don’t want it to be in. It will kill veggies and plants there and continue to kill for years. Salt may seem easy but it is very problematic in landscapes.
