For the last 5 yrs. my Potatoes never get any size.
They look like small new potatoes at the end of the
season and the vines have long since died.

Potatoes need soil that will hold moisture, but not remain soggy wet. They prefer a soil pH of 6.0 to 6.8. If you add too much fertilizer, the plant will put all of its energy into growing new tops, and not much energy into developing tubers. Try to keepthe soil moist until the plants begin to flower, then you can stop watering. If your soil is deep and loose, the roots will form tubers without problem. If your soil is not well-prepared before planting, the potatoes will have to struggle to form large tubers. Try adding some organic matter to your potato bed before planting, or plant your seed potatoes just barely under the soil and hill the plants with additional soil, or straw, as they develop. Keep adding soil or straw as the plants grow, and potatoes will develop within the hills.

Better luck with your crop this season!
