Potato Growin' Bag
One bag holds up to 5 potato plants.
This woven polyethylene bag is 18 inches high and 14 inches in diameter, with reinforced handles to make moving it a snap. Just fill it with 36 quarts of soil or potting mix; the drainage holes at the base keep the soil from becoming too wet, while the generous side flaps let you harvest "underground" when the crops mature!
That's all there is to it: plenty of vertical space to grow a good crop of your favorite spuds. This bag is also useful for onions, carrots, beets, and other root crops, as well as flowers and other veggies. And when the season's over, it washes clean with the hose and stores flat for next year!
