Seed Potato Dormancy & Sprouting
4-6 weeks before plantingSeed potatoes develop shoots (eyes) and are ready for planting when shoots appear 1-2 inches long
Store seed potatoes in a cool (45-50°F), dark, humid location for 4-6 weeks before planting to encourage sprouting. Ensure pieces have at least one or two eyes.
Emergence & Early Growth
2-3 weeksShoots push through soil and first leaves appear above ground within 2-3 weeks of planting
Hill soil around emerging plants as they grow to prevent tuber exposure to light (which turns them green). Keep soil consistently moist but not waterlogged.
Vegetative Growth & Vine Development
4-6 weeksPlant develops bushy foliage, flowering stems, and roots expand underground; underground stolons begin to swell into tubers
Continue hilling soil every 2-3 weeks as plant grows taller. Fertilize with balanced fertilizer or side-dress with compost. Monitor for pests and diseases. Maintain consistent watering.
Flowering & Tuber Enlargement
3-4 weeksSmall purple or white flowers bloom; tubers actively fill out and gain size beneath soil surface
Do not harvest early; flowers indicate tubers are still maturing. Increase watering slightly if weather is dry. Avoid excessive nitrogen fertilizer at this stage.
Maturity & Skin Set
1-2 weeks before harvestFoliage begins to yellow and die back; tuber skins thicken and harden; plant enters senescence
Reduce watering as foliage dies back to help tubers cure and mature fully. Stop fertilizing. Harvest after foliage has mostly died back.

Common Pests
-
Hand-pick beetles and egg clusters; use row covers early in season; apply neem oil or spinosad if infestation is severe; rotate crops yearly
-
Use row covers to exclude insects; reflective mulch; encourage natural predators; insecticidal soap if needed
-
Spray with strong water stream; use insecticidal soap or neem oil; encourage ladybugs and parasitic wasps
-
Plant disease-resistant varieties; ensure good air circulation; avoid overhead watering; remove and destroy infected foliage immediately; apply copper fungicide preventatively in wet conditions
-
Remove lower leaves as plant grows; avoid overhead watering; mulch to prevent soil splash; apply fungicide if spotted; rotate crops
-
Maintain consistent soil moisture (avoid extremes); lower soil pH below 6.0; rotate crops; choose resistant varieties; avoid fresh manure

Harvest Tips
Harvest French Fingerlings 70-90 days after planting when foliage has mostly died back and vines are dry. Dig carefully with a garden fork to avoid bruising. Cure tubers in a dark, cool (50-60°F), humid location for 1-2 weeks before storage to toughen skins. Store in cool, dark, humid conditions (45-50°F, high humidity) for 3-4 months. For new potatoes, harvest earlier (60-70 days) when plants are still flowering for smaller, creamier tubers.
Fun Facts
- 🌱 French Fingerlings are a heirloom variety that has been cultivated in France since at least the 19th century, making them a true legacy crop with deep historical roots.
- 🌱 The yellow interior of French Fingerlings comes from naturally high levels of carotenoids, which give the potato its characteristic buttery color and slightly richer flavor compared to white potato varieties.
- 🌱 French Fingerlings are smaller than other potato varieties, with each tuber typically weighing only 2-4 ounces, meaning a single plant can produce 10-15 or more individual potatoes perfect for elegant plating.
