Seed Piece & Sprouting
2-3 weeksPlant seed potatoes showing sprouts begin to root and develop underground.
Use seed potatoes treated for disease. Ensure soil temperature is at least 45°F (preferably 55°F+). Plant in loose soil for easy emergence.
Emergence & Early Growth
2-3 weeksShoots break through soil surface; first true leaves appear. Plant grows 4-6 inches tall.
Hill the soil around emerging plants to prevent tuber greening from sun exposure. Maintain consistent moisture and monitor for pests.
Vegetative Growth
4-6 weeksPlant develops bushy, leafy foliage reaching 12-18 inches tall. Underground stolons begin forming.
Hill soil 2-3 times as plant grows to encourage tuber development and prevent light exposure. Apply mulch to retain moisture and regulate soil temperature. Fertilize mid-season with balanced fertilizer.
Flowering & Tuber Development
3-4 weeksPlant produces small white or purple flowers. Below ground, tubers are rapidly enlarging and accumulating starch.
Maintain consistent watering without waterlogging. Cease hilling. Watch for late blight and other diseases in humid conditions.
Maturity & Harvest
1-2 weeksFoliage begins yellowing and dying back; tubers reach full size with mature skin.
Stop watering 2 weeks before harvest to help skin harden. Harvest when foliage has mostly died back or after first light frost.

-
Plant resistant varieties. Ensure good air circulation. Avoid overhead watering. Apply copper fungicide or Bordeaux mixture at first sign. Remove infected foliage promptly.
-
Remove lower leaves as plant grows. Mulch to prevent soil splash. Apply fungicides preventively in humid seasons. Practice crop rotation.
-
Use yellow sticky traps. Remove debris and perennial weeds. Practice 3-4 year crop rotation. Encourage beneficial nematodes.

Harvest Tips
Polka is a mid-season variety ready to harvest 80-100 days after planting. For new potatoes, harvest 2-3 weeks before full maturity by gently digging around plants. For storage potatoes, wait until foliage dies back completely and skin has hardened (test by rubbing—mature skin doesn't flake off). Dig carefully with a fork to avoid bruising. Harvest on a dry day and cure in a cool (50-60°F), dark, well-ventilated space for 2 weeks before storage.
