One word. Concrete.
i was hintinting thay the DDT might have caused dain bramage
When I was a kid, we had a small "patio" (really too small to be called a patio) outside our back door made of rectangular concrete pavers. It was my job to keep it weeded between the pavers. In an elementary school history class I learned about the Romans salting the ground of their enemies to cause starvation from not being able to grow crops. I started taking out the pavers in the spring, and putting down a bed of rock salt, then replacing the pavers. No weeding for the rest of the year.It may be what Hough is referring to but I use the Round Up with the purple on the bottle. It is stronger than the other Round Up's. I also mix it slightly stronger. It seems to kill things pretty good though where I used it last year is now growing vegetation again this year.
I do know that salt works well. I once dumped my water softener brine tank on a section of my front yard. I think it was 3 years before I saw grass there again.
There is a Product called Ortho Ground clear. Comes in a Black gallon can. about $25 per gallon. Not sure active ingredient. When it is nice and dry, mix it strong, and it works pretty well. My rock driveway gets a dose aabout twice a year, and no issues. That's the best I can find OTC, lot cheaper than roundup. Kills Poison Ivy and Locust trees. I'll take it.
