Growing Tips
Hill potatoes when plants are 15-20 cm tall — mound soil around stems to cover developing tubers and prevent greening from light exposure.
Use certified disease-free seed potatoes — most potato diseases are tuber-borne and recycling farm-saved seed spreads infection.
Potatoes need consistent moisture, especially during tuber bulking (flowering stage). Irregular watering causes knobby, cracked tubers.
Avoid planting potatoes in the same field more than once every 3 years — this breaks late blight and nematode cycles.
Stop watering 2 weeks before harvest to let skins set. Mature skin resists damage during harvest and improves storage life.
Store potatoes at 4-7°C with 90% humidity in complete darkness. Light causes greening and solanine buildup (toxic).
