Having a raised garden bed is great in the city¬†because you can fill it with good soil and create a healthy environment for your plants. Install a hoop house made from PVC pipe. To build the raised bed, use 2x10x8 lumper. Predrill the holes at the corners to make it easier to assemble. Butt the ends together and use exterior deck screws to assemble it. If you want the raised bed higher, build another box the same size and stack them. Fasten a wire screen onto the underside of the frame to keep burrowing animals out. Gravel underneath the frame provides good drainage. Make supports for small livestock cages, so the chickens and rabbits can fertilize the soil. Following these steps will get your started toward having sustainable urban living by having your own vegetable garden.
