This solution is pet safe, after it dries.   The 5% white vinegar and salt can burn paws, so it is best to wait unit the solution is dry to welcome them in the area. It will also hurt the eyes if the spray gets into them.

    This might help your understanding of using salt as a weed killer.

    The ramifications go a lot further than just the weeds that may be growing from new seeds blowing into your garden or birds dropping seeds and other ways.

    If you are doing the same thing every year and the weeds are still coming back, does not that make you think there may be a different/better way?

      I double dig my garden before planting. With each shovel full, I break the soil apart and get out the roots. I also mulch at least 3 inches deep and have very few weeds. BTW: Am a Master Gardener.

    I killed a whole rubber tree with salt and vinagar. The tree was too close to the pool so it had to go. The only difference is to cover the stump with trash can so it got no light.
