Troubleshooting
Peruvian Oroya problems — and how to fix them
Peruvian Oroya (Oroya peruviana) 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.
Rot from winter moisture
The most common cause of loss is watering during winter dormancy. Keep completely dry in a cool place from October to March.
Failure to flower
Flowering requires both intense summer sun and a cool winter rest. Indoor plants often need to be moved outside for summer to receive adequate light.
Mealybugs
Inspect the areoles and crown region regularly. Treat with isopropyl alcohol on a fine brush or apply diluted neem oil.
Etiolation
Insufficient light produces elongated, pale growth. Correct gradually — acclimatise over 2-3 weeks when moving to stronger light.
