Seed Piece & Sprouting
2-3 weeksSeed potatoes are planted and develop sprouts over 2-3 weeks. Soil temperature should be 45-50°F minimum.
Use certified seed potatoes with 2-3 eyes each. Plant as soon as soil is workable in spring. Keep soil consistently moist but not waterlogged.
Vegetative Growth
3-4 weeksLeafy green tops emerge and grow vigorously. Underground stolons begin forming tubers at nodes.
Begin hilling soil over plants when 6-8 inches tall; repeat hilling every 2-3 weeks. Remove any flowering potato beetle adults by hand. Water regularly.
Tuber Development
4-6 weeksPotatoes form and enlarge beneath hilled soil. Plant canopy becomes dense and bushy.
Maintain consistent moisture; this is critical for tuber sizing. Continue hilling to prevent greening of tubers. Mulch to retain soil moisture and keep tubers covered.
Flowering & Maturation
3-4 weeksSmall flowers appear (usually white or pale pink). Foliage may show slight decline. Tubers reach desired size.
For new potatoes, harvest at this stage (70-90 days). For storage potatoes, wait until foliage dies back completely. Reduce watering gradually.
Harvest & Curing
1-2 weeksFoliage yellows and dies back naturally. Tubers develop thicker skins and are ready for harvest.
Wait 1-2 weeks after foliage dies before harvesting to allow skins to cure. Harvest on a dry day. Cure harvested potatoes in cool, dark, humid location for 2 weeks.

Common Pests
-
Hand-pick adults and egg clusters; use row covers on young plants; apply neem oil or spinosad; encourage natural predators like ladybugs
-
Spray with strong water stream; use insecticidal soap; encourage beneficial insects; reflective mulch may deter
-
Ensure good air circulation; avoid overhead watering; remove infected foliage; apply copper fungicide; plant resistant varieties
-
Crop rotation; remove debris; trap with pieces of potato buried in soil; beneficial nematodes; avoid planting in recently tilled sod
-
Maintain soil pH below 6.5; ensure adequate moisture; avoid over-liming; practice crop rotation; choose resistant varieties

Harvest Tips
For new potatoes, harvest 70-90 days after planting when plants are still flowering by carefully digging around plants. For full-size mature potatoes, wait until foliage dies back completely (90-120 days), then harvest on a dry day. Gently dig to avoid bruising tubers. Cure freshly harvested potatoes in a cool (50-60°F), humid, dark location for 2 weeks to toughen skins for storage. Store in cool, dark conditions (45-50°F) with high humidity for up to 3-4 months.
Fun Facts
- 🌱 Amarilla potatoes are native to the high-altitude Andes mountains of Peru and Bolivia, where potatoes were first domesticated over 7,000 years ago.
- 🌱 The natural yellow pigment in Amarilla comes from carotenoid compounds, the same antioxidants found in carrots and squash, making them more nutritious than white potato varieties.
- 🌱 A single potato plant can produce 5-10 tubers from one seed piece, making potatoes one of the most productive and calorie-efficient crops for home gardeners.
