Troubleshooting
Zamia Pumila problems — and how to fix them
Zamia Pumila (Zamia pumila) 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.
Caudex or root rot
The most common killer, caused by overwatering or poor drainage. Use a gritty mix, water only when dry, and never let the swollen stem sit in wet soil.
Scale and mealybugs
Asian cycad scale and mealybugs cling to frond undersides and stems. Inspect regularly and treat with horticultural oil; heavy scale can yellow and kill fronds.
Stretched, weak fronds
Too little light produces pale, elongated leaves. Move to a brighter position with some direct sun to keep fronds stiff and deep green.
Very slow recovery
Coontie grows slowly and resents disturbance; a stalled or single-flush plant is usually normal, not sick. Avoid frequent repotting and be patient between flushes.
