We have a city not too far from us that takes the residents leaves every fall and composts them. Then they give out that compost for free, for anyone willing to shovel it. We have used that every year, to help fill our raised beds. Our raised beds are on the ground so I guess they aren't really "raised". We outlined the garden with wood and put cardboard down to kill the grass. Then we filled in the garden. With the free compost(which we call black gold), chicken bedding, and top soil that we have bought over the years. Here is a good picture from this past spring, when we doubled the garden
