Troubleshooting
Spinystar Cactus problems — and how to fix them
Spinystar Cactus (Escobaria vivipara) 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 in wet winter conditions
Even cold-hardy specimens are vulnerable to rot if kept wet in winter. This is the species' Achilles heel. Keep dry from late autumn onwards.
Failure to flower indoors
This prairie native requires a genuine cold-dry dormancy to set flower buds. Move to an unheated greenhouse or outdoor spot in winter for best results.
Scale insects
Hard, waxy scale can appear along the ribs and areoles. Treat with targeted insecticidal soap or neem oil.
Etiolation in indoor conditions
Without sufficient direct sun the plant becomes elongated. A grow light or outdoor summer placement will restore compact growth.
Sunscald after long periods indoors
If overwintered inside, acclimatise slowly to outdoor sun in spring to prevent pale, burnt patches.
