Frequently Asked Questions

What pest or disease commonly affects Solanum tuberosum (potato) like German Butterball, and how can I manage it?

Late blight (water mold) is a major problem for potatoes, causing dark, water-soaked leaf spots that spread quickly in cool, wet weather. Remove and discard infected tops as soon as you see lesions, and avoid overhead watering; use a preventive fungicide schedule if your area is prone to late blight. For less severity, keep plants spaced for airflow and keep soil hilled so tubers stay covered.

How often should I water German Butterball potato during the main growing phase?

During active tuber bulking (roughly mid-season through about 75% of the way to maturity), keep soil evenly moist but not waterlogged—about 1–2 inches of water per week depending on heat and soil type. Aim to water deeply after the top 1 inch of soil dries, and stop regular watering as the vines start to yellow so tubers can firm up. Consistent moisture prevents misshapen tubers; soggy soil increases rot risk.

How do I know when German Butterball potatoes are ready to harvest?

Harvest when plants reach about 95 days from planting and the foliage begins to die back naturally. For “new” potatoes, you can dig earlier, but for full-size German Butterball, wait until skins are set—scrape a tuber gently with your thumb; it should not rub off easily. Choose a dry day, dig carefully, and cure the tubers for about 1–2 weeks in a cool, dark, humid place if you plan to store them.
