I was planning on going to the hardware store for cinder blocks to build a raised bed-but not now that you gave me the dresser idea!!! Thank you so much for a great and FREE idea!If your not great at building you can buy a pre made raised bed but they are kind of high. My advice is however find a buddy that is good with building trade them eggs to show you how to do it. Your not going to be happy with just one..... Just ask my husbandseriously though a power drill, a handsaw, a tape measure and a hammer are a girls best friend! If you try to build one and you don't get it " perfect" then it has character and you will feel proud that YOU made it . You can also repurpose old dressers to make raised beds. Pull out the drawers and cut out the dividers drill holes in the bottom ( aka the back ) or cut it off completely. I actually love those because I do have clay soil and have trouble growing root vegetables. I love the deep ones for carrots.
I would also look into a few fruit trees (not sure how big your yard is ?) but most fruit trees don't mind wet feet.
