Frequently Asked Questions
What’s the most common disease to watch for on Solanum tuberosum (potatoes) and how do I manage it?
Watch for late blight (often starts as dark, greasy-looking leaf spots that spread quickly in cool, humid weather). Remove and bag infected foliage immediately, avoid overhead watering, and water at the soil line; if it’s spreading, use a labeled late-blight fungicide early and repeat as directed. Also plant in well-drained soil and don’t work the plants when leaves are wet to reduce spread.
How can I tell when to harvest Solanum tuberosum ‘King Edward’?
Harvest when the plants’ tops have died back and the tuber skins have set—typically around 90 days, but use the foliage as your main cue. In the final week, stop watering and gently dig one plant to test: the skin should resist rubbing off. Cure freshly harvested tubers in a cool, dark, airy place for about 1–2 weeks before storage.
