Ken,
What are Landscaping Code Requirements?
We have a landscaped area directly in front of our theatre. There are hedges along the walkways. The open ground area was covered with pea gravel. The weeds were starting to poke through. Our landlord (after some prodding) put down wood chips right over the pea gravel. This works for a season or two. But it's cheap and can be freshened every year or two. We don't need to water it or mow it, but they do attract a lot of cigarette butts.
We have a nice olive tree, which attracts pickers every time the olives are ripe.
