in your specific case, i'm curious about how much
sand you have blowing around there?

About once ever two weeks we have about a 35 MPH wind
full of sand. No where is immune to weed seeds. But,
then again, our average rainfall per year (not month)
is only 7 inches, so the weeds have very short lives.
Well, except for tumble weeds.
