I chose this antique wagon from Vietnam to grow Yukon Gold. I purchased this wagon about 7 years ago at an antique fair and it has been a favorite garden piece of mine ever since. I used linen burlap for the lining and made the bag by tracing the inside of the wagon onto the fabric and sewing it together. It is attached to the top with staples.
Growing potatoes vertically is simple. You will want to make sure you have good drainage in what ever container you choose. Start by adding 6" of compost or good quality soil. Next you will want to cut up an already sprouting potato trying to get 2 or more sprouts per cut if possible, I keep potatoes in the kitchen drawer to sprout. Place potato pieces sprouting side up and cover with another 6" of compost. As the plant breaks through the top of the soil you are going to add another 6" of soil to the top. Continue this process of adding soil every time plant growth breaks through until the soil reaches the top. At that point you enjoy watching the beautiful green foliage as it grows and blooms. Harvest when greens start to die back long after the plant flowers.
Here is one we harvested for Easter. I harvested early so I could get another batch started. I just couldn't resist!
