Seed Piece & Sprouting
2-3 weeksSeed pieces are planted in cool soil (50-70°F); sprouts emerge within 2-3 weeks as soil warms
Use certified disease-free seed potatoes; plant in spring after soil warms slightly; ensure good drainage to prevent rot
Vegetative Growth
3-4 weeksShoots emerge and vines develop; plants grow 8-12 inches tall with compound leaves; stolons (underground stems) form where tubers will develop
Hill soil around plants as they grow to prevent tuber greening; maintain consistent moisture; begin fertilizing at vine emergence if soil is poor
Active Tuber Development
4-6 weeksPlants reach full height (12-18 inches); flowers appear (white to pink); rapid tuber enlargement occurs underground as plants allocate resources to potato formation
Maintain steady watering; avoid nutrient deficiencies; monitor for pests and diseases; weed management is critical
Maturation & Vine Senescence
2-3 weeksVines yellow and die back; tubers finish developing and skin thickens; plant signals readiness for harvest as foliage fully browns
Reduce watering 2-3 weeks before harvest to toughen skins; allow vines to die back naturally for better storage; do not harvest in rain
Harvest & Storage
Harvest 1-2 weeks; storage ongoingTubers are dug from soil; cured in cool, humid, dark conditions (50-60°F, 85-90% humidity) for 7-10 days to heal skin; ready for long-term storage
Harvest when vines are fully dead; handle tubers gently to avoid bruising; store at 45-50°F in darkness; excellent storage life (4-6 months)
