Troubleshooting
Microsorum pteropus 'Trident' problems — and how to fix them
Microsorum pteropus 'Trident' (Microsorum pteropus 'Trident') 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
Bury the rhizome in substrate and it suffocates and rots black. Always leave the rhizome exposed and attached only to hardscape.
Black spots / algae on fronds
Dark spots are often viviparous plantlets (normal) but excess light and low nutrients invite black-brush algae on the slow fronds; reduce light intensity and improve flow.
Melting after planting
New fronds may brown and melt as the plant adapts to a tank; trim dead fronds, keep the rhizome healthy and new growth follows.
Stunted, pale growth
Iron and overall nutrient deficiency yellows the fronds; dose a complete liquid fertiliser and consider gentle CO2.
