Potatoes may be planted as soon as the ground can be worked in the early spring, but you must use good judgment. The soil should be evenly moist, but not wet or soggy. If the soil is water logged when you dig, not only will you risk “caking” the soil, your seed potatoes will probably rot before they even get started.
A day or two before planting, use a sharp, clean knife to slice the larger seed potatoes into two seeds. Each seed should be at least 1 1/2-2inches in size, and must contain at least 1 “eye” or bud. Smaller potatoes may be planted whole. Over the next couple days the cut side of the potato will form a thick callous over the cuts, which will help to prevent it from rotting once planted.
How Much Seed Potato do You Need?
Assume that you get on average 4 potato seeds per pound of potatoes. If you plant a seed potato every 8″ you will need 10 lbs. for a 25′ row, 20 lbs. for a 50′ row and 40 lbs. for 100′ row.
Spacing in Rows: 8-12 inches
Row Spacing: 18-24 inches
