[The Walking Dead (TV)] Why aren't the suburbs more overgrown by now?

It's been a couple of years since the world ended, and people still have fairly nice-looking lawns and shrubs. Are some of the walkers vegetarians?

Those are the remnants of short-lived communities of survivors. The main groups rarely run into them, but there are dozens of small groups spread out over the area in Georgia where the main group is situated. Sometimes they settle enough, and try to restart the old world. Lawns get mowed, grass planted, all the silly bullshit, because their leader is convinced that everything can go back to how it was if we try hard enough. Then a passing herd hears the lawnmower going one sunny Sunday afternoon, and that's that.
