best way to remove a kikuyu grass lawn?
I want to remove my kikuyu grass lawn, hopefully in as organic and earth-friendly a way as possible (but to get rid of it, I'm willing to do a one-time tilling or Roundup spray if that's really what it's going to take...) It spreads everywhere--I tried sheet mulching in some areas and it just came up through 2 feet of cardboard, newspaper, wood chips, manure, etc. and took over my raised beds. What should I do? Can I get rid of it without spraying? Help!
