Troubleshooting
Yukon Gold Potato problems — and how to fix them
Yukon Gold Potato (Solanum tuberosum 'Yukon Gold') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Greening of tubers
Tubers exposed to light turn green and accumulate toxic solanine. Hill soil over developing tubers and store harvested potatoes in the dark.
Late blight
Phytophthora infestans causes brown leaf lesions in cool wet weather and can rot tubers. Space for airflow, water at the base, and choose certified seed; remove infected foliage promptly.
Common scab
Corky raised patches on skins develop in alkaline or dry soil. Keep pH around 5.0-5.5, maintain even moisture during tuber set, and avoid fresh lime or manure.
Hollow heart and cracking
Erratic watering produces internal cavities and cracked tubers, especially in larger Yukon Golds. Keep soil moisture steady through the bulking period.
