Frequently Asked Questions

How do I handle powdery mildew on Adirondack Blue (blue potato) plants?

Powdery mildew shows up as a white, powdery coating on potato leaves that can spread downward as nights stay cool and humid. Remove and discard badly affected foliage early, then improve airflow by spacing plants and avoiding overhead watering. If it keeps recurring, spray a labeled fungicide for potatoes when you first see spots and repeat according to the product directions (especially if wet weather continues).

How often should I water Adirondack Blue potatoes during the main growing phase?

During active tuber growth (about mid-season), keep soil evenly moist but not soggy—aim for about 1–1.5 inches of water per week from rainfall plus irrigation. Water deeply when the top 1 inch of soil feels dry, and after watering avoid leaving water to sit around the stems. Steer clear of letting soil fully dry out for long stretches, as that can reduce tuber size and trigger cracking or irregular growth.

When are Adirondack Blue potatoes ready to harvest and how can I tell?

Harvest at about 90 days, or sooner for “new potatoes,” when the plants begin to yellow and the foliage starts dying back. For final harvest, wait until most vines have died and the skins have set—if you gently rub the potato skin, it should resist peeling. Lift a few plants to check size and skin set before harvesting the whole bed.
