Fingerling Potato

Solanum tuberosum var. fingerling

vegetable

Fingerling potatoes are small, elongated tubers named for their finger-like shape, typically 2-4 inches long. They have thin skins in colors ranging from red to yellow to purple, and creamy, waxy flesh that holds its shape well when cooked. Popular for roasting, boiling, and salads due to their buttery texture and rich flavor.

Growth Stages

1

Seed Piece/Sprout

2-3 weeks

Seed potatoes planted in soil begin sprouting; shoots emerge within 2-3 weeks. Small white roots develop underground.

Keep soil consistently moist and warm (55-70°F ideal). Ensure good drainage to prevent seed rot. Mulch to retain moisture.

2

Vegetative Growth

3-4 weeks

Plants establish stolons (underground runners) that will form tubers. Above ground, leafy green foliage develops rapidly with compound leaves.

Hill soil around stems 2-3 times to encourage tuber formation and prevent greening. Water consistently. Apply balanced fertilizer or compost tea every 3 weeks.

3

Tuber Initiation & Development

4-5 weeks

Stolons swell into small fingerling tubers underground. Above-ground plants continue vigorous growth with flowering beginning.

Maintain consistent watering and light hilling. Monitor for pests and diseases. Avoid over-fertilizing nitrogen, which reduces tuber formation.

4

Bulking/Maturation

3-4 weeks

Tubers increase in size to full fingerling length. Skins begin to thicken and cure. Foliage may yellow and begin to senesce.

Reduce watering slightly as plants mature. Stop hilling. Avoid excessive nitrogen. Watch for late blight and other disease signs.

5

Harvest Readiness

1-2 weeks

Foliage dies back completely or 80% brown. Tubers have firm, mature skins that don't rub off easily. Tubers reach 2-4 inches in length.

Stop watering 1-2 weeks before harvest to allow skins to cure fully. Harvest when foliage is dead and soil dries slightly for easier digging.

Common Pests

  • Hand-pick beetles and egg clusters. Use row covers on young plants. Apply spinosad or neem oil if severe. Rotate crops annually.

  • Spray with insecticidal soap or neem oil. Release ladybugs. Use reflective mulches to deter.

  • Use row covers early. Apply neem oil or pyrethrin. Maintain plant vigor through proper watering.

  • and

    Remove debris and mulch where they hide. Use beer traps or copper barriers. Hand-pick at night.

  • Crop rotation (avoid over 3 years). Beetle traps. Proper drainage to reduce habitat. Beneficial nematodes.

Harvest Tips

Harvest baby fingerlings at 70-90 days by carefully digging with a fork, starting 12 inches from plants. For mature fingerlings, wait until foliage dies back (100-120 days), then dig gently to avoid bruising. Handle carefully as fingerlings bruise easily. Allow tubers to cure in a cool, dark, humid place for 1-2 weeks before storage. Store at 45-50°F in darkness.

Fun Facts

  • 🌱 Fingerling potatoes were nearly extinct until specialty breeders revived them in the 1990s; they're now experiencing a gourmet renaissance.
  • 🌱 The name 'fingerling' comes from their small, finger-like shape and size, distinguishing them from standard round potato varieties.
  • 🌱 Colored fingerlings contain anthocyanins and other polyphenols—powerful antioxidants—especially abundant in purple and red varieties, making them nutritionally superior to white varieties.
