Answer: Rototilling is the first step. Once you've tilled the area, rake out all the old weeds and roots, along with any large stone or pieces of wood you might find. Rake the area smooth and then spread 3-4 inches of organic matter over the top of the entire bed. Dig this in to a depth of about 8", then rake the bed smooth again. It will be ready to plant.
Best wishes with your garden!
