The easiest way to create a new garden bed for the spring is to start in the fall. Lay 2 ply newspaper or cardboard down on the unwanted grass or weeds. Then, pile garden debris, compost and grass clippings right on top of the newspaper. Dig a trench around the new bed, and toss that soil on top of your pile to hold the debris in place for the winter. (Trenching is preferred over edging materials, as all edging materials are difficult to mow around. With a trench, you can mow the grass right up to the garden beds edge!) In the spring, you will have a perfectly prepared planting bed! No back breaking labor or toxic chemicals needed! The grass clippings and other yard debris will die and decompose into plant food.
