And I have had trouble with Round Up, because it works for other people, but for some reason it doesn't work for me. What works for me to kill weeds and keeps them away for a good long time is white vinegar mixed with as much salt as it can take, and you spray it on the weed and soak it in the ground. But that is only something you want to use if you plan on growing NOTHING there for a good long while.
Will a vinegar & salt mixture work to stop weeds & grass growing up through old cracked sidewalk & where old sidewalk meets old pavement, and would it be harmful to the pavement?
I ask because I wound up in this thread and others looking for a way to remove an abundance of weeds in a situation like this... without having to dig & wind up crumbling more of the sidewalk in the process.
The places I have a problem with are within inches to 1-1/2 feet from flowerbeds, lawn, or nice bushes.
I want the weeds GONE from the cracks, but don't want anything that's going to bleed into the lawn, bushes, or flowerbeds.
I don't want to use commercial chemical herbicides, mainly because I'm concerned they might be ineffective because these areas get run off from the neighbor who has professional treatments of their lawn & landscape regularly... so I suspect they have a tolerance from getting weak treatments.
That's how it works right? Acclimating them to poison over generations. I'm assuming that's how they bred round-up impervious vegetable crops on purpose - by exposing them a little at a time, and breeding the ones that were able to survive more & more of it.
What's more I would need something capable of killing grass - because that's also growing there... and probably boosted by low levels of the neighbor's grass fertilizer!!
I'm assuming salt & vinegar would work because it's a broad plant life killer, rather than a chemical targeting only certain plants?
Sounds perfect for a place you don't want anything to grow. But how often do you have to do it?
How sparingly must it be used to be effected but not bleed into other areas or be damaging?
