would you consider an underground barrier? something like vinyl siding,
one foot deep. If not, my uneducated guess is that it will spread about
ten feet eventually. How do I know that? I just consider the grass near
my neighbor fence (he has horses, and two spots near the fence are
where they prefer to manure) compared to the grass away from it (in
poor sandy soil, it is much sparser and not as green).
