• Spacing: Plant seed pieces about 9–12 inches apart in rows spaced 30–36 inches apart.
• Watering: Maintain consistent moisture throughout the growing season, particularly when tubers begin forming.
• Hilling: As plants grow, mound soil around stems to protect developing potatoes from sunlight and increase yields.
• Disease resistance: Resistant to late blight (foliage and tuber), PVA, and common scab. Moderately resistant to early blight, black leg, and PVY.

Harvesting
Kennebec potatoes are typically ready to harvest about 90–110 days after planting. For storage potatoes, allow vines to die back before harvesting. This variety is well known for its excellent storage qualities when properly cured.

History
Kennebec potatoes were developed by the USDA and the Maine Agricultural Experiment Station in Presque Isle, Maine, and released in 1948 from a cross between Chippewa and Katahdin. Named after Maine’s Kennebec River, this variety quickly became a dominant potato across the Northeast and Midwest due to its reliability, high yields, and versatility for fresh market and processing.
