Troubleshooting
Tiraque Sulcorebutia problems — and how to fix them
Tiraque Sulcorebutia (Sulcorebutia tiraquensis) 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
The primary killer of sulcorebutias. Maintain a very dry winter rest and ensure drainage holes are fully open.
Mealybugs in spine base
Densely packed spines provide excellent cover. Inspect monthly and treat early with isopropyl alcohol and neem oil.
Flower colour inconsistency
S. tiraquensis is highly variable in flower colour across forms; this is genetically normal rather than a sign of stress.
Failure to flower
Cool (5-10°C), dry winter essential. Plants kept warm and moist through winter rarely bloom in spring.
Scale
Small brown carapace scales can colonise stems. Remove manually and follow up with neem oil treatment at 7-10 day intervals.
