Step 5: green matter


For a compost to decompose cleanly, it needs equal parts by volume of "green" matter (such as grass clippings or vegetable scraps) and "brown" matter (such as dead leaves, sawdust, or newspaper).  For this first sheet mulch, I didn't have a lot of grass clippings collected yet, so I used some vegetable scraps including some big stuff like corn cobs and whole apples... and then I worried that they might not be done decomposing by springtime, so it was kind of a relief when the sheet mulch had to be taken apart; it gave me the chance to do it properly the second time.
