Borchers' Oroya problems — and how to fix them
Borchers' Oroya (Oroya borchersii) 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.
Root rot
High-altitude cacti are particularly vulnerable to rot when kept warm and wet simultaneously. Ensure thorough drying between waterings and a cool winter rest.
Spider mites
Hot, dry indoor conditions can encourage mite populations. Increase air flow and treat with insecticidal soap if webbing is observed.
Slow growth
Normal for this high-altitude species. Do not over-water or over-feed in an attempt to accelerate growth, as this leads to rot.
Reluctance to flower indoors
Oroya borchersii benefits from a cool, dry winter rest and bright outdoor summer sun to flower. Indoor specimens may need 4-6 hours of direct sunlight.
