Here the things you call “weeds” are just part of the landscape, because what you guys plant as “grass” will seldom live on the thin soil and it slurps up more water than a large family and small herd of cattle, which is wasteful. We plant Comanche Buffalo grass, Sahara Bermuda-stuff that doesn’t need supplemental water.
You have to xeroscape out there to have anything grow in that hardy environment.
