Frequently Asked Questions
What pest or disease is most likely on Solanum tuberosum (potato), and what should I do if I see it?
Late blight (often seen as dark, water-soaked leaf spots that spread quickly, with a grayish fuzz on humid days) is the most damaging disease for potatoes. Remove and destroy infected leaves immediately, avoid wetting foliage when watering, and improve airflow by spacing plants properly. If the problem is spreading, use a labeled late-blight fungicide and reapply according to the product’s schedule and timing for potatoes.
How often should I water during the main growing phase to keep Solanum tuberosum producing tubers?
During active growth and tuber bulking (once plants are established), keep the soil evenly moist but not soggy—aim for about 1–2 inches of water per week depending on heat and soil type. Water deeply so moisture reaches the root zone, and let the top inch of soil dry slightly between waterings to prevent rot. Consistent moisture is especially important after flowering begins; irregular watering can lead to misshapen tubers.
