What is the best depth for planting potato's. Do they need to be "hilled" or is that just a myth. If they need to be planted in hills, what would the planting depth be and how high should the hill be?

Hilling is normally done as the potato plants grow. You will plant the seed potatoes about 3 times deeper in the ground than the size of the seed potato. As the potato plant grows, mound up the soil around the plant, leaving about 6 inches above the soil. This encourages the plant to produce potatoes all the way up the stem.
You can start with a hill too, which is helpful to keep the seed potatoes out of water logged soil, if that is a problem where you grow, as well as providing a little more warmth earlier in the season.
