90d to harvest

Earthy and richly aromatic, Umatilla Russet delivers a classic russet depth with a warm, nutty flavor and a satisfyingly dry, fluffy bite. Its thick, russeted skin sets the stage for dependable roasting—while the interior stays creamy and smooth for mashing, and holds beautifully for hearty fries and wedges. For gardeners who love the moment of harvest, this 90-day variety rewards with uniform, well-filled tubers and a distinctly rugged, old-world character.

Frequently Asked Questions

What pest or disease is most likely on Solanum tuberosum (potatoes), and what should I do?
Watch for late blight (often starts as brown, water-soaked spots on leaves and spreads fast in cool, wet weather). Remove and destroy infected foliage immediately, improve airflow by keeping plants properly hilled, and avoid overhead watering; if the problem is spreading in your area, use a labeled late-blight fungicide early and follow the label schedule.
How do I tell when Umatilla Russet (Solanum tuberosum) is ready to harvest?
Harvest at about 90 days when the plants’ foliage has mostly yellowed and begun to die back, and the tuber skins are set (they don’t rub off easily when gently scratched). For best storage quality, cure the harvested tubers in a cool, dark, humid place for about 1–2 weeks before storing.
