Potato Planting Tips:
Put straw down on top of your ridge of soil.
Cut your seed potatoes so you have at least 3 eyes on each part of the potato.
Lay your cut seed potatoes about 6-8in apart on top of the straw.
Cover the potatoes with straw.
Mound more soil on top of the straw.
Wait for the potatoes plants to grow. The straw will help you have lots cleaner potatoes
 when you harvest them and should help to keep them from rotting.
