Bolivian Zamia problems — and how to fix them
Bolivian Zamia (Zamia boliviana) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Frond tip dieback from low humidity
Brown, dry tips on leaflets that spread inward indicate insufficient atmospheric humidity. This species is more sensitive to dry air than xeric Zamia relatives. Raise humidity above 60% consistently and avoid placing near heating or air-conditioning outlets.
Root rot in poorly draining substrate
Heavy or moisture-retaining soils lead to anaerobic conditions and Phytophthora or Pythium root rot, causing frond yellowing and caudex softness. Always use freely draining substrate and ensure pot drainage is unobstructed. Treat early infections with a phosphonate fungicide.
