Seed Piece Sprouting
1-2 weeksCut seed potatoes develop small shoots within 1-2 weeks of planting. Eyes begin to sprout from the cut pieces underground.
Ensure soil temperature is 45°F or higher. Plant when soil is workable but not wet. Keep soil consistently moist but not soggy.
Vegetative Growth
4-6 weeksPlants emerge from soil and develop compound leaves. Stems grow tall and bushy with leafy foliage. Underground, stolons extend and tuber initiation begins.
Hill soil around plants as they grow to prevent green tuber shoulders. Water consistently. Begin pest monitoring. Apply mulch to retain moisture.
Tuber Development & Flowering
3-4 weeksSmall white to pale pink flowers appear on stems. Underground, tubers swell and develop. Foliage remains vigorous and green.
Continue hilling if needed. Maintain steady water supply—critical for tuber expansion. Monitor for late blight and other diseases. Remove flower buds if desired to redirect energy to tubers.
Tuber Maturation
2-3 weeksFoliage begins to yellow and decline. Tubers reach full size and develop characteristic golden skin. Skin becomes firm and set.
Reduce watering slightly as plant senesces. Do not disturb plants unnecessarily. This is the ideal 'new potato' harvest window if preferred.
Harvest Ready
At harvest timeFoliage has mostly died back to brown and withered. Tubers are fully mature with set skin. Plants are ready for digging.
Wait 2-3 weeks after foliage dies before harvesting to allow skin to fully cure. This improves storage. Harvest carefully to avoid bruising tender fingerling tubers.

Harvest Tips
Yellow Finn potatoes can be harvested as 'new potatoes' 60-70 days after planting when tubers are small and tender, or left in the ground until full maturity (90+ days). For storage, harvest after foliage has died back completely. Dig carefully with a fork to avoid bruising the delicate fingerling shape. Store unwashed tubers in a cool (45-50°F), dark, humid location with good air circulation. Can keep 3-4 months when properly stored.
Fun Facts
- 🌱 Yellow Finn is an heirloom variety originating from South America (likely Peru or Chile) and has been grown in home gardens and by specialty farmers for decades, prized for its exceptional flavor that distinguishes it from common russet potatoes.
- 🌱 The term 'fingerling' refers to the tuber's small, elongated shape resembling human fingers—Yellow Finn typically yields 2-4 ounce tubers with a length of 2-3 inches, making them perfect for single-serving roasted preparations.
- 🌱 Unlike starchy russets, Yellow Finn is a waxy potato variety with lower starch content and higher moisture, which is why it holds its shape when cooked and never becomes fluffy or mealy, making it superior for potato salads and gratins.
