Wow thanks for all the replys!! Ive been working on my beds as much as the weather and kiddos will allow! Ive gotten several of them cut ready to assemble but only one completely done and staked down. I only use recycled or repurposed materials. These were made from unused pre fab fencing that hadn't been stained i reinforced them with repurposed pallet wood and lumber that was thrown out on a job site that was to warped to build with. I stapled recycled thick plastic birdseed bags around the inside to help keep the wood from rotting and painted the outside with deck paint i had left over from the summer. Also stapled recovered chicken wire from my local recycling center on the underneath to keep the moles out. I did a lasagna stack with cardboard being the base, then straw, compost, top soil, grass clippings, top soil agian and compost.
