Troubleshooting
Mandaianum Blue Star Fern problems — and how to fix them
Mandaianum Blue Star Fern (Phlebodium aureum 'Mandaianum') 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.
Browning, crisping crested edges
The ruffled margins show low humidity and hard-water salts first. Raise humidity, use softer water, and flush the pot of accumulated salts.
Rhizome rot
From burying the rhizome or keeping the mix soggy. Rest the furry rhizome on top of an airy mix and let the surface dry between waterings.
Loss of blue colour
Too much direct sun. Relocate to bright, filtered light.
Weak, flattened crests
Low light reduces the characteristic crisping. Provide brighter indirect light to firm up the frilled margins.
