Wooden shipping pallets are a popular material for DIY projects, especially for pallet gardens. They are portable, inexpensive, easy to make, and perfect for urban or small-space gardening.
Pallets used for gardens or indoor projects should always be heat treated as opposed to chemically treated. Look for the HT stamp on the wood before taking your pallets home.
Next, grab your plants. Try lining them up in different arrangements before you plant to make sure you have enough room for each to grow and for the arrangement to looks its best. Then, start digging! Transfer your plants from container to pallet garden. Leave the plant tags in to identify each plant later.
