Troubleshooting
La Ratte Fingerling Potato problems — and how to fix them
La Ratte Fingerling Potato (Solanum tuberosum 'La Ratte') 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.
Late blight
Wet, cool weather browns foliage and rots tubers. Improve spacing and airflow, water at the soil line, and remove infected haulm quickly.
Awkward harvest losses
Long, knobbly fingerlings break and get speared during lifting. Grow in loose, stone-free soil and dig carefully by hand or fork from the side.
Scab
Corky lesions mar the thin skin in dry, alkaline soil. Keep pH acidic and moisture even during tuber set; avoid fresh lime.
Greening
Surface-exposed tubers green and become toxic. Hill soil over the stolon zone and store the crop in complete darkness.
