If you plan on gardening during a long term SHTF event, the potato is one of your best friends. Not only are potatoes easy to grow, but they also store well, are easy to cook with, and any remaining potatoes at the end of the year can be replanted for next years crop.
Unlike a lot of crops that require special storage, such as canning and/or drying, just keep potatoes dry and in a cool dark place and they will store for close to a year.
Small potatoes can be eaten straight out of the ground. Larger ones can be baked, boiled, mashed, or made into a soup.
Potatoes grow well in loose soil free from rocks, sticks, tree roots and other obstructions. Work the soil with a tiller, plow, disk,,, something that will break the soil up. Make the rows, add fertilizer, I like to mix the fertilizer into the soil using a tiller, then plant the seed potatoes. Plant the seed potatoes about 3 inches deep and about 12 – 18 inches apart.
