No-Chemical Grass Killer
If you're looking to kill some grass to create a new garden bed, you don't need chemicals or expensive rental machines—or much effort, really—if you bide your time and use flattened cardboard boxes. Lay the cardboard over the grass you want to get rid of and weight it down. It will have done its job when the grass shrivels up and turns brown. You can leave it in place and dig right through it if you're planting a few shrubs, but if you're digging a lot of holes, it's easy enough to pull up the cardboard.
