So I planted my potatoes in an old bathtub. I put about 1" of dirt on the bottom. Then I covered them about 1" deep. As they have sprouted and the tops of the potatoes plants are coming above the dirt I cover them again. I keep doing this until the bathtub is full then I let the potatoes just finsh doing their thing.
This is my first time to "do" potatoes but so far they are growing like crazy and I have to cover the plants every few days with more dirt. So far the tub is over half full and it was a garden-tub size tub! I will let ya'll know how they do when I harvest them
