Frequently Asked Questions

What pest or disease commonly hits Solanum tuberosum (potatoes) and how can I manage it?

Late blight (often starts as dark, water-soaked spots on leaves and can quickly spread under humid conditions) is one of the most damaging diseases in potatoes. Remove and destroy infected foliage immediately when you see spreading lesions, and avoid overhead watering to keep leaves drier. If your area has frequent late-blight pressure, use an approved potato fungicide schedule labeled for late blight as soon as symptoms or risk conditions appear.

How often should I water Solanum tuberosum during active tuber growth?

During tuber bulking (roughly mid-season through about 90 days), keep soil evenly moist but not waterlogged—aim for about 1–1.5 inches of water per week depending on heat and rainfall. Water deeply when the top 1–2 inches of soil dry out, and maintain steady moisture because irregular watering can contribute to misshapen tubers. Stop heavy watering a couple of weeks before harvest so skins firm up and tubers store better.

How do I know Centennial Russet (Solanum tuberosum) is ready to harvest?

Harvest when plants naturally die back and the vines have yellowed and mostly collapsed—typically around 105 days from planting. Before lifting, test tuber skin by gently rubbing it with your thumb; harvested-ready skins resist peeling. For best quality, harvest on a dry day and cure tubers 7–10 days in a cool, dark, ventilated place.

Earthy aroma leads the way with Centennial Russet—an inviting, deep russet fragrance that hints at its richly satisfying, dry-mealy bite. Tubers mature to an even, elongated shape with a rugged russet skin and a warm, creamy interior that turns velvety when cooked, making it a standout for roasting and baking, as well as classic fries and hearty mashes. Grow Centennial Russet for dependable, market-ready harvests and the kind of texture that holds its character from pan to plate.

Sowing Tips

Transplant Conditions

Wait until soil reaches 45°F and nights stay above 35°F before moving outdoors.

Expert Note

Plant certified seed potatoes when soil warms enough to keep sprouts from rotting, then hill as vines grow to increase tuber yield.
