On a very large 20' wide and 4' deep 'pile' I make trenches in which I put kitchen scraps and coffee grounds. (Visualize a rectangle, and the trenches are the lines from top to bottom) Each 'line' is a trench that is a shovelwidth wide. I dig each trench down a foot or so, sprinkle a bit with water, and then put the scraps in, and sprinkle again. If it's very hot outside, I cover the trench with wet newspaper, and then cover the whole trench with either straw or dried weeds, and then water. Within a few weeks the newspaper and scraps are gone, and I have beautiful black soil. I shovel the soil onto a framed large screen which I put on the wheelbarrow, and gently move my hands over the soil so that the soil and some worms that are still there fall into the wheelbarrow. What's left are any little rocks or other undesirables which I pile up next to my worm pile (just in case there are some worms hiding in the rocks, I want them to have access to food, so they can saunter over to a trench and hunker down.) Then I take what's in the wheelbarrow and dump it into a large bucket. Then I take trowelfuls of soil, lay it on my potting table in some mounds, and go pick vegetables for a while. When I come back, I scrape away the outsides of the mounds, and when I get down to the worms (they'll burrow to get away from the light)and any sowbugs, I pick them out and put them into a small container that has soil in it - the contents of that container will be put back into a trench eventually. I keep wheedling away at the piles until I have only soil and no worms. And the soil is so scrumptious to the plants. Once I mistakenly forgot a little squash seeding and when I finally put it into the garden, it was puny and yellow. I put some of the magical soil around it, and within such a short time, the plant was deep deep green and very happy. Whew...and then I start all over again. After I've put the contents of one trench into the wheelbarrow, I have ready the next fill for the trench. At the front of the trench, I mark with a stake with the date and a letter (A,B, C, etc.) Then in my garden book I make the notes about each trench: the date I harvested the soil, and what I put back into the trench, and then I know how long it took for whatever I put in to work and be ready. My husband tells people that the reason I am so many hours down in the garden is because I am naming my worms.
