Select pallets stamped with the letters "HT," which indicates that they have been heat-treated, and not
treated with chemicals that can leach into the soil and contaminate plants meant to be consumed such as herbs, vegetables and fruit.
Cut the pallet into thirds. 2 full pallets were used here. 4′x4′ posts screwed to the corners and voila, a beautifully gridded garden bed. Prepare the area for the raised beds by removing as many weeds as possible, and make it as flat as possible. Use a garden spade to remove all stones that may create an uneven surface, level any raised spots, fill in depressions, and rake the entire area smooth and flat to provide a solid base for the pallets. Combine equal parts soil with equal parts compost in a wheelbarrow or bucket. Use the mixture to fill in the spaces between the deck boards, packing it into all visible spaces until it is spilling out over the top and sides. Plant seeds or seedlings in the soil in the open sections between the deck boards, spacing them the same distance as recommended for planting in a traditional garden.
