Frequently Asked Questions

Bintje potatoes: how do I manage early blight (Alternaria) if I see leaf spots?

Early blight shows up as small dark brown spots on older leaves that expand into concentric rings, often with yellowing around them. Remove and discard infected leaves promptly and avoid wetting foliage when watering; use drip irrigation if possible. If the problem is spreading, apply a labeled potato fungicide according to the label and repeat on the recommended interval, especially during humid weather.

How often should I water Bintje potatoes during the main growing phase to prevent tuber problems?

During active bulking (roughly weeks 6–12 after emergence), keep soil evenly moist but not soggy—aim for about 1–2 inches of water per week depending on rainfall and heat. Check by digging 4–6 inches down: if it’s dry at that depth, water deeply; if it stays wet or squishes when squeezed, hold off to avoid disease and misshapen tubers. Stop heavy watering about 10–14 days before harvest to help skins set.

When are Bintje potatoes ready to harvest, and how can I tell?

Bintje is typically ready around 90 days, but harvest timing is best judged by the plants: when foliage yellows and dies back and the stems can be easily snapped, you’re ready. Gently dig one plant to confirm tuber size and check that skins are firm enough that they won’t rub off easily. If you need a “new potato” harvest, dig earlier when tubers are golf-ball sized, but for full storage quality wait for the full skin set at dieback.
