First, choose a larger tuber for seed. Every year after the “frost drop”, the mining of purple and yam on the market, pre-sale with a knife cut with potato tubers 50 to 100 grams of potato buds, together with 50 to 150 grams of small tubers, collected after the election of a good soil moisture 15 cm soil cover, remove the spring planting planting.

Trench ditch planting,
