Nerve plant brown leaf tips and edges: causes and what to do
6 results in the diagnosis tree begin with brown tips and edges, 3 of them marked likely when the answers fit. They are ordered here for Nerve plant (Fittonia albivenis), using what its sources say about humidity, soil moisture, cold tolerance, watering and feeding and one problem recorded for it.

Fittonia albivenis is a species of flowering plant in the family Acanthaceae, native to the rainforests of Colombia, Peru, Bolivia, Ecuador and northern Brazil. An evergreen perennial, it is notable for its dark green foliage with strongly contrasting white or red veins. Wikipedia, CC BY-SA 4.0
Native range: S. Trop. America (wet tropical). Also sold as Jewel Plant, Mosaic Plant, painted net-leaf, Silver Fittonia, Silver Nerve and Silver Nerve Plant.

How this shows up on a Nerve plant
Dry, curled edges on leaves near a heater
A yellow halo sits just inside the brown edge on the nerve plant, and new leaves often come in already tipped with brown during the heating season.
Dry air takes water from the leaf surface continuously, and the tissue at the edge is last in the queue for what the roots send up. Penn State Extension notes there is no single humidity figure that suits every indoor plant.
Telling it apart: What else in the room changed. Edges that browned when the radiators came on point at the air rather than at the watering.
Penn State Extension · read 13 September 2026Possible causes, likeliest first for a Nerve plant
Most likely too little water
Ranked higher because Nerve plant's recorded problems point this way.
- Moist but well-drained RHS · read 13 September 2026
Why: Soil dry two inches down leaves the roots nothing to send up, and the leaf edges are the last tissue in line.
What to try:
- Water thoroughly, until it runs from the drainage hole.Useful: pot with drainage holes
- Check the soil with a finger every few days rather than watering on a fixed day.Useful: moisture meter
What would settle it: Water it thoroughly and watch the next new leaves. If they come in with clean edges under steadier watering, the edges were thirst.
Most likely cold
Ranked higher for Nerve plant because of what its sources say.
Its RHS hardiness rating puts this plant's cold floor at 15°C or above, so a cold windowsill at night is a strong explanation.
- H1A — warmer than 15°C RHS · read 13 September 2026
Why: Soft, dark patches rather than crisp ones are damaged tissue rather than dried tissue.
What to try:
- Move it away from the glass at night, or keep the curtain on the room side of the nerve plant.
- Leave damaged leaves until new growth appears, then remove the worst of them.
What would settle it: Where the nerve plant sits at night, and what the glass feels like at that hour. Damage that appeared after one cold night, on the side facing the window, is the pattern.
Most likely a build-up of salts in the soil
- Loam, Sand; pH Neutral RHS · read 13 September 2026
Why: Minerals from tap water and fertiliser are left behind as water evaporates, and a white crust on the compost or the pot rim is where they show.
What to try:
- Water slowly and heavily until several times the pot's volume has run through the drainage hole, to wash the salts out.Useful: pot with drainage holes
- Scrape off the top layer of crusted compost and replace it.
What would settle it: Scrape the crust. If it is gritty and dissolves in water it is mineral; if it is fluffy it is mould, which is a different problem.
Less likely for a Nerve plant, still possible

What this does not cover
This page orders a decision tree's results using a plant's sourced care. It has not seen your plant, its pot or its window, and two problems at once are common: that is the usual reason a confident answer turns out wrong. The questions in the diagnosis tool narrow it further than a list can.
