Troubleshooting
Roller Jovibarba problems — and how to fix them
Roller Jovibarba (Jovibarba globifera) 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 from overwatering
The globular offsets and dense mat of rosettes can trap moisture at the crown. Always water at the base, not overhead, and ensure the pot has generous drainage holes. Clay or terracotta pots help wick away excess moisture.
Rust fungus
Orange or brown pustules on leaves indicate a fungal rust infection, which is more common in humid, shaded conditions. Remove affected tissue, improve airflow, and treat with a copper-based fungicide if necessary.
Mealy bugs
Waxy white colonies may appear between tight rosette leaves, especially when plants are grown indoors with low airflow. Dab with isopropyl alcohol on a cotton swab or use a dilute insecticidal soap spray.
