Potatoes in a tower?

摘要

This unique method allows you to grow 20 pounds of spuds in an area less than 4 square feet.Potatoes are versatile, delicious, and rich in vitamins. And if you're able to grow them successfully, the harvest can keep for the entire winter (something not even tasty tomatoes can do). Despite these positive traits, potatoes have always scared me. Not because they have creepy-looking "eyes" nor because my grandma used to say they were poisonous if you ate them raw. Potatoes frighten me because they can be needy when it comes to their growing conditions, they take up a lot of room, and they can introduce a plethora of diseases into your garden without warning; in addition, they're a favorite delicacy of voles.
