Sink your spoon into the promise of Rose Gold—tubers with a luminous, blush-rose skin that feels satin-smooth in the hand and reveals a creamy, golden interior.

A true heirloom for gardeners who love dependable, satisfying harvests at about 90 days, when the color turns unmistakably radiant.

Frequently Asked Questions

What disease is most likely to affect Solanum tuberosum (potatoes) and how can I manage it?

Early blight (Alternaria) often shows up as dark, concentric spots on lower leaves and can spread upward in warm, humid weather. Remove and destroy infected foliage promptly, and avoid wetting leaves by watering at the soil line. Space plants to improve airflow and rotate potatoes out of the same bed for several years to reduce disease carryover.

How often should I water potatoes during their main growing phase?

During tuber bulking (roughly from flowering until harvest, about midseason), keep soil evenly moist—aim for about 1 inch (2.5 cm) of water per week, split into 1–2 deep waterings. Let the top 1–2 inches (2.5–5 cm) dry slightly between waterings, because consistently waterlogged soil can reduce tuber quality. Stop regular deep watering about 7–10 days before harvest so skins set and tubers store better.

How do I tell when to harvest Solanum tuberosum?

Harvest when plants begin to yellow and die back, typically around 90 days from planting, and the tuber skins have “set” (won’t rub off easily). For new potatoes, you can harvest a bit earlier by gently digging one or two plants before full dieback. After harvest, cure tubers in a cool, dark, ventilated spot for 1–2 weeks before long-term storage.
