Garbage Can Potatoes

I thought this was pretty neat and would like to try it next year. Has anyone done this?

Basically you take a clean 30 gallon garbage can and drill a few holes on the bottom and a few inches up the side for drainage. Mix a cup of fertilizer with about 2/3 of a bag of potting soil and add to the garbage can. Take some small potatoes for your seed potatoes and place them about 5 inches apart in the can. Cover with the remaining third of soil. Keep the soil moist but not soggy and make sure you have about 4-6 hours of direct sunlight daily. As the plants start to grow, mound the soil up around the stems leaving the leaves uncovered. When the plants start to flower, it's harvest time and you can reach in and grab the new potatoes. Later when the stems start to wither and die it's time to spill the trash can over and harvest the rest of the potatoes. Add the soil to your flower garden and not your vegetable garden as there may be pests you don't want to introduce into your vegetables.

And there you have it, garbage can tomatoes!
