Guidance for growers:
Plant in rows 26 cm wide and 15 to 20 cm deep.
You don't have to plant all of them in one go. For instance, plant half of them and store the other half for planting later.
Store seed potatoes in a cool, dry place, and not completely in the dark otherwise the shoot growth will be accelerated.
After planting, the development of tubers will be faster in warm months than in earlier, colder months.
