Killing Weeds with Salt

Can salt be used to kill weeds, blackberry bushes, and grass in places you don't want it? (We have 6 dogs and prefer not to use chemicals/poisons from the store, to avoid any contamination to my babies).

Hardiness Zone: 7b

My Dad used to pour boiling water over weeds and it killed them every time.

In a word...yes. You are much better off to use a hoe, or hand weed around the plants. It will take a little time, but is better for your plants and your garden (salt may prevent other things from growing for one or more seasons, depending on how much you use and how you apply it.) Once you weed, you can use mulch to discourage the weeds from coming back. That and a few minutes of hand-weeding each week will keep your plants looking great!

I saw some of your members advice about killing weeds and grass. I had a question about using salt. I have an area that is 8' x 24' and filled with pea gravel. I have a problem with weeds and grass growing in the area. I was wondering if anyone knows if I use the salt to kill it, will the salt effect a ceder elm and a lady banks rose I have growing on each end of the area.
