Whitelock's Ceratozamia problems — and how to fix them
Whitelock's Ceratozamia (Ceratozamia whitelockiana) 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.
Low humidity leaf damage
Leaflet tips turn brown and crispy in dry indoor air, especially in heated rooms in winter. Increase humidity above 60% with a humidifier or pebble tray, and keep the plant away from heat sources.
Root rot
Persistent waterlogging at the caudex causes rot that is usually fatal. Ensure excellent drainage and do not allow pots to sit in water. Yellowing fronds accompanied by a soft caudex base indicate rot.
Scale insects
Soft and armoured scales can colonise leaflets and stems, producing honeydew and sooty mould. Treat with horticultural oil sprays repeated every 10–14 days; check leaf undersides and stem junctions regularly.
