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.
