Troubleshooting
Mulanje Cycad problems — and how to fix them
Mulanje Cycad (Encephalartos gratus) 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.
Interveinal chlorosis on new fronds
Yellowing between the veins of newly emerging leaflets indicates manganese or iron deficiency, common in alkaline or waterlogged substrates. Apply a chelated iron/manganese foliar spray and ensure pH remains at 5.5–6.5. Improve drainage to restore nutrient uptake.
Frond browning in dry conditions
Unlike desert cycads, Encephalartos gratus shows tip and margin browning when root zone moisture is too low during the growing season. Increase watering frequency in summer or move containers out of drying wind. Maintain some consistent moisture through the growing period.
Scale and mealybug
Both cycad scale (Aulacaspis yasumatsui) and mealybugs attack fronds and the trunk base. Monitor regularly; treat at first sign with horticultural oil or systemic neonicotinoid. Remove and bag infested fronds. Newly acquired plants should be quarantined for several weeks.
