Troubleshooting
Waterberg Cycad problems — and how to fix them
Waterberg Cycad (Encephalartos eugene-maraisii) 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 rot from overwatering
The most common cause of death in cultivation. Symptoms include soft, discoloured tissue at the stem base and a foul odour. Remove all rotted material with sterile tools, treat with fungicide, allow to dry thoroughly, and replant in fresh gritty mix.
Cycad scale (Aulacaspis yasumatsui)
Devastating scale pest that forms white encrustations on all plant surfaces. Early detection is critical. Treat with repeated horticultural oil applications at 7–10 day intervals or a soil drench of systemic insecticide. Isolate affected plants to prevent spread.
Leaf chlorosis (manganese deficiency)
New fronds emerge yellow or pale green, often linked to alkaline potting medium or overwatering limiting manganese uptake. Apply chelated manganese as a foliar spray or use a cycad-specific fertiliser with micronutrients. Check soil pH and correct if above 7.5.
