Fired Up - Gardener says she fills her raised beds with 3-4" of paper shred, then quickly burns it to kill the weeds. She said it did not leave a mark on the wood. I would top with cardboard afterwards for extra weed protection,
Another great way to grow potatoes! I'd like to try this one, reed fencing, tomato cage, rebar, a single layer of compost and rice straw in the bottom, topped only with rice straw as the potatoes grow. It WILL take a lot of watering, but might give a much better harvest.
