Propagating potatoes by dividing

To grow, the potato needs only a piece of tuber and a sprout. In difficult times, thick potato slices have even been planted.

Cutting planting tubers is not necessary if there are enough tubers available. It was used in times of need, when potato supplies were running low in the spring, to ensure that potatoes were still available for food and animal feed. The large tubers were cut crosswise. The crown half, where the most buds were located, was planted, while the cut portion with the umbilical end could be used for eating.

Tubers can be cut in half to increase the number of perennials in expensive seed potatoes. To ensure that the potato halves to be planted have the same number of buds, the tubers are cut lengthwise. While they are laid out for pre-germination, the cut wound heals and corks. Freshly cut tubers should not be planted, as the cut surfaces could rot in the soil.

"Eye-potting" refers to cutting seed potatoes into small pieces, each with an eye. The eye is cut out in a cylindrical shape along with a piece of tuber flesh. This allows 6–8 pieces to be obtained from one tuber. The pieces should be dried thoroughly before being planted in pots. Only after rooting and sprouting are they planted in the garden, spaced 20 cm apart. Eye-potting can be used when only a few tubers of a variety are available to propagate them.

What do potatoes taste like? While in this country, the tubers are often described as having a neutral flavor, Italians call them "tartuffli," or little truffles. This sounds like a completely different, unique taste, and it's what "potato sommelier" Heidi Lorey wants to introduce us to in her new book "Kartoffelliebe" (Eugen Ulmer Publishing).
