How to completely eliminate a lawn?
I need some advice on how to completely eliminate my "lawn." I have a small (20' x 30') urban backyard that was neglected for a number of years before we moved in. Any grass that was once there has now been completely choked out by spearmint and wild violets. I'd like to kill those off completely (well, maybe keeping some of the violets) and either put down flagstone or a sturdy groundcover that will hold up to kids playing on it.
Any advice for how to get rid of what's there? Pull it all out by hand? Smother it with black plastic? Act like it's grass and rent a turf cutter? I've always been an apartment dweller and am a total novice when it comes to (what seems to me) large flat areas...
