There is a good reason why potatoes are one of the most popular vegetables in the home garden. In 1537, the Spanish conquistadores discovered the potatoes and brought them back to Europe on their return trip. The first potatoes arrived in North America in 1621. Today, potatoes are one of the largest food crops in the world, with the United States alone growing about 35 billion pounds of potatoes every year.
Potatoes require full sun to grow.
Because they are aggressively rooting plants, they will produce the best crop when planted in a light, loose, well-drained but moisture retentive loam. Potatoes prefer a slightly acid soil with a pH of 5.8-6.5 . Fortunately, however, potatoes are very adaptable and will usually produce a respectable crop, even when the soil conditions are less than perfect. Potatoes should be rotated on a 3-year program. This means, you need 3-suitable sites if you want to grow potatoes every year.
