Troubleshooting
Ceratozamia mexicana problems — and how to fix them
Ceratozamia mexicana (Ceratozamia mexicana) 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.
Leaf scorch in direct sun
Exposed to strong sun the fronds yellow and brown. Grow in part shade or bright filtered light to keep the foliage deep green.
Stem and root rot
Overwatering or poorly drained soil rots the short trunk. Use a free-draining, humus-rich mix and keep the soil evenly moist but never waterlogged.
Damaged new flush
Emerging soft fronds are easily marked by pests, sun or handling. Protect tender new growth and avoid disturbing it until the leaves harden off.
Scale and mealybug
Sap-sucking pests collect on the leaflets and rachis. Treat with horticultural oil or insecticidal soap and check new leaves regularly.
