Troubleshooting
Red Nerve Plant problems — and how to fix them
Red Nerve Plant (Fittonia albivenis) 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.
Wilting ('fainting')
Fittonia collapses dramatically when the soil dries out, but recovers quickly with prompt watering. Use this as a visual watering reminder rather than a cause for concern.
Brown leaf edges
Low humidity is the usual cause. Move to a terrarium or add a humidity tray. Cold draughts can also cause edge browning.
Leggy, pale growth
Insufficient light causes weak, elongated stems and faded vein colour. Move to a brighter position — but not direct sun.
Root rot
Overwatering in a pot without drainage leads to soggy roots. Always use a pot with drainage holes and a well-aerated mix.
Fungus gnats
Consistently moist soil encourages gnat larvae. Allow the surface to dry slightly between waterings and use yellow sticky traps.
