Pallet Gardening: Pallets can be recycled and used in a whole new way. Simply find a place to put a pallet and fill it with potting soil. Use the wood openings to plant in. You can grow your salad greens in a small amount of space, and it is a good way to recycle old pallets.
Raised Bed Gardening. I love this layout. The stones create a pathway through the garden. Climbing plants can be planted along the trellis. Flowers can be planted along the path. Herbs and veggies can be planted in the raised garden beds, and are protected from little critters eating them before you do!
