When you receive your seed potatoes unpack them immediately and lay them in trays in a cool, light place until you are ready to plant them. A shed or a garage is ideal.
To get your potatoes off to a flying start we recommend that you chit the early varieties. Chitting is the process of keeping seed potatoes in a cool, light, frost-free place to encourage shoots (chits) to grow prior to planting. Place them in a seed tray or individually in the sections of egg boxes. A good chit is firm, green shoot about 2.5 cm (1") long. Long, white chits indicate too much heat and not enough light.
Chitting speeds up growth and encourages the earliest possible crop. For the very early varieties chitting is essential but it is not necessary with the later varieties.
