Troubleshooting
Emperor Sago problems — and how to fix them
Emperor Sago (Cycas taitungensis) 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.
Root and crown rot
Overwatering, particularly during the winter rest, rots the caudex. Use gritty compost, water only when well dried out, and ensure pots drain freely.
Manganese deficiency (frizzle top)
New fronds emerge stunted, yellow and frizzled when manganese is short. A manganese-containing palm feed prevents and corrects it.
Cycad scale
White crusting scale colonises the fronds and can be persistent. Treat early and repeatedly with horticultural oil, and isolate from other cycads.
Etiolated, floppy fronds
Too little light produces weak, overlong fronds. Move to a much brighter spot and rotate the plant for even, sturdy growth.
