Frequently Asked Questions

What pest or disease is most likely on Solanum tuberosum (potato), and how do I prevent and treat it?

Watch for late blight (water-soaked leaf spots that rapidly spread) and early blight (target-like brown spots). At the first signs, remove heavily infected leaves and improve airflow (space plants and avoid wetting foliage), then use a labeled potato fungicide and follow the interval on the label. Also remove volunteer potato plants and keep mulch off the soil surface to reduce spore splash onto lower leaves.

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

During active foliage growth and tuber bulking, keep the soil consistently evenly moist—about 1 to 2 inches (2.5–5 cm) of water per week total, adjusting for rainfall. Water deeply when the top 1 inch of soil feels dry, because soggy conditions limit tuber oxygen and can invite rot. Aim water at the base of the plants, not the leaves, to reduce disease pressure.

How can I tell when to harvest Solanum tuberosum (Red Chieftain potato)?

Harvest around 90 days from planting when the plants’ tops begin to yellow and die back, indicating tubers have thickened skins. For “new potatoes,” you can harvest earlier by gently digging one plant while leaving the rest to mature. After harvest, cure potatoes for about 10–14 days in a cool, dark, humid area to help skins toughen before storage.
