Frequently Asked Questions

What pests or diseases commonly affect Solanum tuberosum (potato) and how can I control them in a home garden?

Watch for late blight and early blight, which show up as leaf spots that spread quickly—remove and destroy affected foliage immediately and avoid wetting leaves during watering. For insect pressure, check for Colorado potato beetles on the undersides of leaves; hand-pick adults and larvae early, and if needed use an insecticidal soap or a labeled spinosad/BT product that’s specifically allowed for potatoes. Improve airflow by spacing plants properly and keep the soil hilled so tubers stay covered, which reduces sun damage and some disease pressure.

How often should I water Solanum tuberosum during the main growing phase, and what soil moisture level should I aim for?

During active growth and bulking (roughly weeks after emergence through mid-season), keep the soil evenly moist but not waterlogged—about 1 inch (2.5 cm) of water per week total, adjusted for rain and heat. Water deeply to moisten the ridges where tubers form, then let the top couple inches dry slightly before watering again to prevent rot and disease. A good test is that the soil feels like a wrung-out sponge at ridge depth, not soggy or dusty.

How do I tell when Solanum tuberosum (potatoes) like ‘Chieftain’ are ready to harvest?

Harvest when the plants are naturally dying back and the foliage has yellowed—‘Chieftain’ typically takes about 95 days from planting. Before lifting, gently dig one hill to check that tubers have set skins that won’t rub off easily; if you can scrape the skin off with light friction, leave them longer. For best storage quality, cure harvested tubers for 7–10 days in a cool, dry, shaded spot after harvest.
