Frequently Asked Questions

What pest or disease most often affects Solanum tuberosum (potato), and what should I do if I see it?

Potatoes commonly suffer from late blight (dark, water-soaked leaf spots that spread quickly in humid weather). Remove and destroy infected leaves and avoid overhead watering; water at the soil line. If the problem is spreading, use a labeled fungicide for potato/late blight and reapply according to the label, especially during wet stretches.

How often should I water potatoes during the main growing phase, and what soil moisture level do they need?

During active tuber bulking (roughly mid-season until the plants begin to yellow), keep soil consistently evenly moist but not soggy. Aim for about 1–2 inches of water per week total (rain included), adjusting so the soil is damp 4–6 inches down rather than waterlogged. Irregular heavy watering followed by dry spells can reduce tuber quality, so keep moisture steady.

How can I tell when my potatoes (Solanum tuberosum) are ready to harvest?

Harvest when plants are fully yellowing and the vines start to die back; for many gardens this is around 90 days. Check a tuber by gently digging—when the skin is set (won’t rub off easily), it’s ready. For better storage, wait a few more days after the foliage dies back, then cure harvested tubers in a cool, dark, well-ventilated place.
