Norstog's Ceratozamia problems — and how to fix them
Norstog's Ceratozamia (Ceratozamia norstogii) 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.
New frond wilting or failure to unfurl
Caused by underwatering during the critical flush period, low humidity, or root disturbance. Maintain consistent moisture and humidity when new fronds are emerging. Avoid repotting during active flush. A mist of lukewarm water on emerging fronds helps in dry environments.
Spider mites in dry conditions
Fine webbing and stippled, dulled leaflets indicate spider mite infestation, favoured by warm, dry air. Increase humidity, spray forcefully with water on leaf undersides, and apply neem oil or insecticidal soap spray weekly until clear.
Root rot in poorly drained substrate
Despite preferring moist conditions, C. norstogii is susceptible to Pythium and Phytophthora root rots in dense, waterlogged soil. Ensure the mix drains freely, use pots with drainage holes, and avoid over-watering during low-light winter months.
