I've been walking over the spot where we're going to move our trailer onto, and I already knew that there is a LOT of work to be done before I can do much planting (if nothing else, the fact that it's been scraped off smooth twice in the past 30 years, not sure why). I have a lot of brush cleaning, trash removing and soil amending to do...this I know how to do. But just past where the driveway is going to be, will be across the drive from the trailer, in a area, oh, about 30 or so square feet, there is a layer of coal on top of the ground. Does anyone have any ideas how to remove it w/o picking up every darn peice of it... or can I till it in with my soil amendments without hurting my plants? Thanks!
