Hi there, I live in a condo building and the landscaper we've hired has proposed using Roundup in our courtyard area to deal with weeds. Concerned about the fact that Roundup has been deemed a probable carcinogen by the World Health Organization (and banned in the Netherlands, with bans considered elsewhere as well), I've been trying to advocate in favour of a non-toxic alternative, such as concentrated vinegar. However, the landscaper has indicated that for deep-rooted weeds and small tree saplings (our most common types of weeds), there is no real effective alternative to Roundup, and that in fact Roundup is not as bad as it is sometimes made out to be. I'm having trouble understanding this, and also having trouble seeing how there could be no effective alternative to it. Afterall, what would they use in the Netherlands? Any suggestions that anyone might have as to environmentally- and health-friendly alternatives to Roundup that would be effective on deep-rooted weeds and small tree saplings, would be greatly appreciated. Thanks!
