Industrial pallet cleaned up, broken and missing boards replaced, and a board added to the bottom to retain soil. There is a 1/2" PVC irrigation system inside running through the internal centerboard. The vertical pipes feed to horizontal pipes that have a tiny hole drilled into them to water the lower portions of the garden. Cover all sides and the bottom first with yard/weed cloth and then with burlap. I poked holes through the burlap and yard cloth so I could tie it to the fence so it won't fall over. Now it's ready for potting mix. Be sure to pack the soil down so it is full. These took just over three cubic ft. I cut small holes through the burlap and yard cloth and packed the soil back to make room for the seedlings. I stuffed each seedling into a hole and pulled the burlap into place just under the leaves.
I stapled the plant ID tags to the pallet so I can remember what everything is. If you're going to plant edibles in your pallet as I did, be sure to find one that was heat treated as opposed to fumigated with pesticides. More info on pallet treatment on our page dedicated to pallet safety.
