Microsorum pteropus 'Narrow' problems — and how to fix them
Microsorum pteropus 'Narrow' (Microsorum pteropus 'Narrow') 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
Burying the rhizome in substrate rots it; keep it exposed and attached to hardscape only.
Brown frond melt
Fronds may brown and melt after relocation as the plant acclimatises; remove dead leaves and protect the rhizome until new fronds emerge.
Black-brush algae
Slow growth plus excess light leaves fronds vulnerable to dark algae; lower light, improve flow and keep nutrients balanced.
Nutrient-deficient yellowing
Pale or translucent fronds signal iron/potassium shortfall; dose a complete liquid fertiliser regularly.
