Have you ever wanted to build or buy a garden box? The cost of pre-built boxes and lumber itself is extremely expensive. Fortunately you can build one for just a few dollars in nails and tools if you use wood pallets.
First, you will need to find a pallet or two, depending on how large you want your box. A good source is to check craigslist.org in your area under the free section and search for pallets or wood. A lot of times people give away the pallets that the pallet recyclers won't pay for.
