Most kinds of potatoes can be planted during cool weather.But John Masiunas of the University of Illinois Extension says it may be best to wait until after the last winter freeze.
and the best soil temperature is better between fifteen and twenty-one degrees Celsius.potatoes will not form if the soil temperature reaches twenty-seven degrees.
Potatoes are started from "seed pieces." These are either small whole potatoes or potatoes cut into pieces.Each piece should weigh about forty to sixty grams.The experts at the University of Illinois say pieces of less than thirty grams may not produce as much.
Each piece must have at least one good "eye," the small dark spot where a sprout will grow.Soon after the pieces are cut,plant them twenty-five to thirty centimeters apart.Cover them in a furrow between two and one-half and seven and one-half centimeters deep.
For potatoes,the best soil is should not too wet.If possible,in the year before you plant potatoes,plant a cover crop to improve the soil and the potato production.
You can wait till the fall to harvest potatoes,make sure to handle potatoes carefully.They can bruise easily,and damaged potatoes can quickly go bad.
