I heard years ago that SALT would kill a tree, grass, etc.; however, I do not know if this is true.
We have an area between the pool decking and the deck which has/had red clay. We dug it down a few inches, added a layer of sand and covered in white rocks. We did this because the main waterhose for the pool is attached to our deck and the hose would always get some dirt on it every time it was used which ended up on the pool deck or in the pool.
The problem is that weeds just LOVE this area and we have spent lots of $ on weed spray which doesn't work all that well. It just kinda makes them mad and when they come back I try to pull them up. This is hard work. So, my question is this:
Will salt kill weeds? I hope the answer will be 'yes' because I can get a 50# bag from the feed & seed for about $6.
