In the past I have used rock salt (from my water softener) to treat unwanted plant growth coming up through my pavers. I would dilute it with water, 1:4 in a 2 gallon spay bottle and go at it.
Although effective, I am curious to know if this is deleterious to the pavers over time. I don't want to use herbicides because of children and domestic pet considerations.
Would appreciate if anyone is willing to share info or experiences.
Thanx.
John
