Place the tubers in the cavities of an egg carton or crate, and arrange your potatoes loosely, with the eyes and future sprouts on top. If some of the potatoes are large enough, divide them in half and leave the cut part underneath.
Place in a light, dry and airy place at an ideal temperature of 10 to 15°. The sprouts will not take long to appear, it takes about 4 to 6 weeks.
Plant in April-May, as soon as they have reached two to three centimeters and have a purple color, but only if the temperature of the ground is about 12°. As long as frosts are to be feared, once the sprouts are out of the ground, mound them gradually to protect them.
You can also use your own potatoes to sprout them. In this case, pull the tubers out of the ground about a month before they mature, having selected the best ones, and let them rest on the ground for a few weeks.
