Troubleshooting
Byfield Fern Cycad problems — and how to fix them
Byfield Fern Cycad (Bowenia spectabilis) 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.
Leaflet browning and crisp edges
Caused by low humidity, dry air from heating or air conditioning, or direct sun. Move to a shadier position and increase ambient humidity; trim affected leaflets cleanly.
Root and crown rot
The underground tuber is prone to rot in waterlogged conditions. Ensure the planting medium drains freely and avoid overwatering during cooler months.
Mealybugs
Can infest the base of emerging fronds and tuber crown. Treat with a cotton swab dipped in isopropyl alcohol; for widespread infestations, apply a systemic insecticide labelled for ornamental cycads.
