sheet mulching small front yard? some q's
This seems like a silly question, but I just can't figure it out.
I'm a newbie wanting to sheet mulch my front yard lawn. My little plots are somewhat small (one on the left is about 12'x10') and the grade is not insignificant When I read the sheet mulching instructions in Gaia's Garden, it seems like I'm going to need to stack at least 13" worth of material on the lawn.
Its hard to tell in the pic, but the grass slopes somewhat steeply down to the sidewalk, meaning anything I put there will most surely end up on the concrete. Do I put in edging and hope no one kicks it down so I can pile things inside? Should I dig the whole area out? Dig a trench along the borders? Any advice is appreciated!
