Step 1) Purchase organic potatoes from your local grocery store or farmer’s market. Conventionally grown potatoes are usually treated with chemicals that prevent eyes from growing; however we need these eyes to grow our potato plants. When a potato produces little sprouts, those sprouts are often referred to as “eyes”.
Step 2) Place a few potatoes in a dark and cool place. February or early March is the ideal time to do this. Occasionally check to see if eyes are forming.

Step 6) When the plant is eight inches tall, bury half of it with compost or soil. Keep repeating until you run out of space or the plant blooms. As mentioned above, we bury part of the plant so the formerly exposed stems will produce more tubers once underground. This will greatly increase the yield of potatoes, as the roots and tubers to do not keep growing deep into the ground. So, to create more layers of tubers, we have to keep raising the dirt level.
Step 7) When the leaves start to wither and die, stop watering for a few weeks and then harvest. Dig gently around the plant, being careful not to bruise the potatoes. If potatoes are growing in a container, it’s easier to dump out all of the dirt and look for the potatoes, rather than dig for them.
Step 8) Brush off excess dirt and leave potatoes in a root cellar or a dry, dark place for a few weeks. This will allow the skin to cure and then the potatoes will be able to store for many months.
