Take about two to three old pallets and with a saws all cut down the sides of the pallets and take the nails out. (We went to Home Depot and they gave us all the pallets we wanted.)
Then you will cut the boards and make a box 5ft. and nail together.
Then you will make another box and nail together 51 inches. Then turn at an angle.
Then you will make another box and nail together at 39 inches and the top box at 27 inches. Turning them at different angles.
Then you will place the boxes where you want to put them and fill with dirts. We actually filled them with dirt from Home Depot for raised flowerbeds.
Then plant your vegetables and flowers. Water them and you will have a easy, beautiful garden or flowers. The dirt and plants is where you spend your money.
