Wide-leaf Ceratozamia problems — and how to fix them
Wide-leaf Ceratozamia (Ceratozamia euryphyllidia) 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.
Leaflet tip burn
Broad leaflets are sensitive to low humidity and dry air from heating systems. Maintain humidity above 50% and keep the plant away from vents and radiators.
Scale and mealybug
Inspect the caudex, leaflet bases, and undersides regularly. Treat mealybugs with isopropyl alcohol on a cotton swab; use horticultural oil spray for broader infestations.
Slow or no new flush
Ceratozamia produces one flush of fronds per year; no flush in a given season is normal if light or temperatures are suboptimal. Ensure adequate warmth (above 18 °C) in spring to trigger flushing.

Most wide-leaf ceratozamia issues are care-mismatch, not bad luck. Dial in the basics:
