Seed Piece Sprouting
2-3 weeksPlanted seed pieces develop sprouts; shoots emerge from soil
Ensure consistent soil moisture and temperature between 45-60°F. Keep soil temperature above 45°F for sprouting.
Vegetative Growth
3-4 weeksStems and leaves develop rapidly; plant establishes above-ground foliage
Apply mulch (3-4 inches) to retain moisture, suppress weeds, and prevent greening of tubers. Hill soil around plants as they grow. Fertilize with balanced fertilizer.
Flowering
2-3 weeksPlant produces blue-purple flowers; indicates active tuber formation below ground
Maintain consistent watering. Do not remove flowers; they indicate the plant is developing tubers. Continue hilling if needed.
Tuber Development & Maturation
3-4 weeksUnderground tubers expand; foliage may yellow slightly. Blue pigmentation develops in tubers.
Maintain even moisture to prevent cracking or malformed tubers. Reduce nitrogen fertilizer. Avoid overwatering near end of season.
Harvest Ready
ImmediateFoliage yellows and dies back; tubers reach full size and color. Skins harden.
Stop watering 2 weeks before harvest to toughen skins. Harvest when vines completely die back for best storage.

Harvest Tips
Harvest when foliage completely dies back, typically 70-90 days after planting. Carefully dig tubers to avoid bruising, which affects storage and appearance. Leave tubers in the ground for 2 weeks after vine death to harden skins. Dig on a dry day and cure in cool (45-60°F), dark, humid place for 2 weeks before storage. Store at 40-50°F with 85-90% humidity.
Fun Facts
- 🌱 Adirondack Blue was developed at Cornell University's breeding program in the 1990s as a specialty potato with superior nutrition and disease resistance.
- 🌱 The blue-purple color comes from anthocyanins that develop in sunlight, so storing them in light actually preserves more of their beneficial compounds.
- 🌱 This variety was one of the first colored potatoes to gain widespread commercial availability in North America, helping spark the specialty potato market.
