|Best way to cut seed potatos,ie.are eyes necessary on each cut segment? Do bigger pieces make bigger plants? and have you heard about putting an old tire around the plant instead of hilling?|
|Each segment should have 2-3 eyes. The part of the potato containing the eyes acts as a package of carbohydrates for the new sprouts. As soon as they reach the sunlight and grow leaves, the plants will make their own energy (through photosynthesis) and the underground parts will rot. So, there's no real advantage to having larger pieces of the seed potato. As long as each piece has 2-3 eyes, you'll get a healthy potato plant. (Believe it or not, when potatoes were scarce, people actually planted potato peels and most of them grew into potato plants!)
You can grow your potatoes in a chicken wire cylinder, adding straw as the tops grow; you can do the same thing in old tires (you'll need at least three tires). Start the plants as usual, set a tire around them, fill the tire with straw as the plant grows. When the top of the plant pokes up through the top of the tire, set a second one on top of the first and fill in around the sides with straw. The potatoes will develop in the straw within the tires which makes for easy harvesting.
