How do you water potatoes?

the same as outside

Actually, it takes more preparation to grow them indoors. With a drill, or hammer and a large nail, puncture several drain holes in the bottom of a 5-gallon bucket. You should have a large pot or tray to set the bucket in, to catch any drainage during watering. Add soil to the bucket until it is about three fourths of the way full. Cut the eyes from the potatoes, leaving about a half inch piece of potato surrounding the eye. Plant one eye per 5-gallon bucket about an inch deep and keep the soil moist in a sunny area. When the potato bush grows to about 5 or 6 inches tall, you will add a little more soil to create a hill. You may need to do this again as it grows taller and bushier. You should have potatoes underground within 3 or 4 months. Outdoors, we know when it is time to harvest because the ground will crack. I'm not sure the soil will actually crack indoors because it may be too moist. You can also purchase potato sacks made just for growing potatoes in.
