Microsorum pteropus 'Needle Leaf' problems — and how to fix them
Microsorum pteropus 'Needle Leaf' (Microsorum pteropus 'Needle Leaf') 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.
Rhizome rot from burial
Substrate burial rots the rhizome; keep it exposed and only the roots in contact with hardscape.
Algae on fine fronds
The thin, slow-growing needles trap and show algae readily; moderate the light and maintain good flow and nutrient balance.
Frond melt after transfer
Expect some browning and melting as the plant adjusts to a new tank; trim the dead fronds and wait for fresh growth from the rhizome.
Yellowing from poor nutrition
Pale needles indicate iron/potassium deficiency; correct with a complete liquid fertiliser dosed to the water column.
