I'm working on my house out in the country and my wife loves to walk around outside barefoot. That's impossible right now because the yard is full of those damn little stickers. What can I do to have that full plush grass with no stickers? The yard was seeded about 10 years ago with Bermuda grass. Of course Bahaya (sp?) has moved in from the fields and I've thrown out some centipede seed over the years.
