Gardeners traditionally hill potatoes but this method takes up space. Grow bags for potatoes are an excellent solution for patio or small space gardeners. Learn more about planting potatoes in bags here.
When I discovered that the potato grow bags cost $20 each I decided to try using my old reusable grocery bags to grow my potatoes in this year. Add 3" of soil to bottom, add potatoes eye side up, cover with additional 4" of soil. Once plant is 8" high add more soil. Keep adding soil until bag is full. Once plant starts to die and wilt, stop watering. Wait a couple of weeks and dump bag out. Harvest your home grown potatoes
