Frequently Asked Questions


How often should I water Solanum tuberosum during its main tuber-building phase?
From about weeks 4–10 (when plants are actively growing and tubers are forming), water to keep the soil consistently moist but not soggy. In typical home gardens, that usually means about 1–2 inches of water per week, split into 1–2 watering sessions; adjust so the top 2–4 inches of soil feel evenly moist, not wet. Avoid letting it dry out completely—uneven moisture can lead to misshapen or cracked tubers.
How can I tell when my Pontiac potatoes are ready to harvest (Solanum tuberosum, ~95 days)?
Check plant maturity by counting from planting (Pontiac typically fits the ~95-day window) and by observing plant dieback—vines should start yellowing and dying back. For a “new potato” harvest, dig lightly earlier, but for full-size tubers wait until most foliage has naturally died back and the skins are firm enough to resist rubbing off gently. Dig carefully with a fork to avoid cuts, then cure in a cool, airy place for 1–2 weeks before storage.
