Growth Stages

1

Sprouting

2-3 weeks

Seed 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.

2

Vegetative Growth

3-4 weeks

Bushy 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.

3

Flowering

2-3 weeks

Small 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.

4

Tuber Development

3-4 weeks

Flowers 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.

5

Maturity & Harvest

1-2 weeks before harvest

Foliage 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.

Harvest Tips

Harvest at full maturity (70-90 days) when vines have died back completely. Carefully dig tubers with a fork to avoid bruising. For storage, cure tubers in a dark, cool (50-60°F), humid place for 2 weeks before moving to long-term storage at 38-45°F. Rosalita stores well for 3-4 months.
