Is the fastest way to make a large amount of leaf mold to pile it up and cover with something (plastic, carpet) ? In the last place we put the leaves in black bags and hide the under shrubs and a year later it was great. In this place we have probably 10X as many leaves so I've got 2x2 metres of leaves in a pile (mostly beech). I'm not sure if it needs covering (after watering) or not. I'd like it to rot down within a year as we don't have space for 2 years of leaves... Oh, and we've run the mower over some of the leaves..
