Sprouting
2-3 weeksSeed potatoes develop sprouts; shoots emerge from soil surface
Ensure soil temperature reaches 45-50°F before planting. Keep soil moist but not soggy to prevent rot.
Vegetative Growth
3-4 weeksBushy foliage with compound leaves develops; vines grow 12-18 inches tall
Provide consistent watering and begin hilling soil around plants when vines reach 6 inches. Apply balanced fertilizer if soil lacks nutrients.
Flowering
2-3 weeksSmall white, pink, or purple flowers appear on branch tips; tuber initiation begins underground
Maintain steady watering as tubers are forming. Avoid nitrogen-heavy fertilizer to prevent excessive leafy growth.
Tuber Development
3-4 weeksFlowers fade; underground tubers expand rapidly with characteristic rose-red skin developing
Continue consistent watering—this stage is critical. Hill soil if any tubers become exposed to prevent greening.
Maturity & Harvest
1-2 weeks before harvestFoliage begins to yellow and die back; tubers have reached full size with firm skin
Stop watering 1-2 weeks before harvest to let skins harden. Harvest when vines are completely dead or after a light frost.
