    A lot of plants have a heavy need for magnesium, which is what Epsom salts are composed of. My highbush blueberries get a handful each, a couple of times a year. I would try pickling salt and pickling vinegar.

    If you have researched this you will see epsom salt is proven to work.FYI

    If the weeds are on a path or drive you can use household salt to kill them,just pour salt on them.

    Plain vinegar works for weed killing alone, but, I have also seen the recipe Janet mentioned

    From what I understand, Epsom Salt (magnesium sulfate) is actually a great fertilizer. I use a mixture of vinegar, a few drops of dish soap and a 14 cup of salt- all shaken in a spray bottle and it's worked great for pesky weeds in my gardens. Since it's close to fall, if you have annoying peek through weeds between bricks or patio blocks etc. now is a great time to sprinkle baking soda on them to kill the weeds before they germinate in the spring.

    No Epsom salt is not a weed killer, it would be a weed grower. Use straight vinegar poured on or you could mix it with rock salt, like they make ice cream with. Be really careful this will be a powerful grass killer ( and anything else it touches ). GL

    Note: once you use the vinegar NOTHING will grow there. It is great for driveways/sidewalks but not for gardens. :-)
