  1. How long do you have to wait if you want to plant something else in the same spot after the weds have died? I just moved and the weeds at my new place are out of control. Thanks


    1. Hi! I’m not sure, but I think it is at least a couple of years. The salt really kills the nutrients in the soil. It might not take as long if you add new soil to the location. I’d definitely test it out first before you plant a bunch of stuff there!


    1. Yes, Round up is a very toxic two animals and the environment and that’s why you don’t want to use it!


  2. I tried this & it really worked great!! It’s not for really big projects, but is wonderful for weeds on the borders of flower beds & in cracks of brick work, etc. Do be careful though because it will kill whatever it touches, so don’t get it too close to your flowers. It is a great solution for those small projects.
