Troubleshooting
Candia Sulcorebutia problems — and how to fix them
Candia Sulcorebutia (Sulcorebutia candiae) 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 cool damp conditions
The most frequent cause of loss. Keep virtually dry and at 5-10°C over winter for a safe dormancy.
Mealybugs
Inspect regularly along the spine bases. Treat with isopropyl alcohol swabs and follow with neem oil spray.
Stunted growth
May indicate compacted or nutrient-depleted old compost. Repot into fresh mix every 2-3 years and resume light fertilising.
Failure to flower
A genuine cold dry winter at 5-10°C triggers bud formation. Without this rest, the plant will not bloom reliably.
Etiolation
Low light causes loose, untidy spine arrangement and elongated growth. Maximise sun exposure to maintain the characteristic tight form.
