How to care for Nerve Plant

sunlight

In its tropical forest home, Nerve Plant grows beneath a leafy canopy. Give it bright, filtered light indoors, away from harsh sun that can scorch its thin, colourful leaves.

Bright indirect light

Place it near an east- or north-facing window, or a little back from a brighter window behind a sheer curtain. This keeps growth compact and leaf veins vivid.

Medium indirect light (tolerated)

It can manage a moderately lit spot, but may become less colourful and stretch toward the light. Move it closer to a bright window if new growth is small or leggy.

Keep the leaves out of direct midday or afternoon sun, especially through glass.

watering

Keep the soil lightly and evenly moist: Fittonia wilts quickly when it dries out, but its fine roots also rot in waterlogged compost.

Spring — summer

Check every few days and water about every 3–5 days in bright, warm conditions. Water thoroughly when the top 1 cm of soil feels just dry, then let excess drain away.

Autumn — winter

Growth slows in lower light, so watering is often needed roughly every 7–10 days. Check the top 1–2 cm first; do not let the whole root ball dry out.

A sudden floppy look usually means thirst—check the soil and water promptly rather than watering on a fixed calendar.

Warmth, brighter light, small terracotta pots, and airy mixes dry faster; cool rooms, low light, and larger plastic pots stay wet longer.

Never leave the pot sitting in water. Constantly saturated soil can cause root rot.

humidity

Preferred humidity

60–80%

Fittonia grows along the humid forest floor, so it looks its best in consistently moist air. Average household humidity of around 40–60% is usually workable, but growth may slow and leaf edges can crisp if the air stays dry.

Crisp brown edges, curling leaves, or frequent dramatic drooping usually mean the air is too dry.

Acceptable minimum

About 40%

Keep it away from radiators, air-conditioning, and cold draughts, which dry the foliage quickly. Humidity often drops indoors during the heating season, so check it more closely then.

A small humidifier nearby is the most reliable way to keep a Nerve Plant happy.
  • Group it with other plants to create a slightly more humid pocket.
  • Place it in a bright bathroom or kitchen if it will receive indirect light.
  • Use a pebble tray as a modest boost, but do not let the pot sit in water.

temperature

Preferred temperature

18–24°C (65–75°F)

Winter minimum

15°C (59°F)

Native to warm tropical forest floors, Nerve Plant prefers steady indoor warmth. Keep it away from chilly windows and air-conditioning; cooler conditions slow growth and can trigger leaf drop.

Place it in a room that stays above 15°C (59°F) overnight, rather than right against glass.
Cold drafts and sudden temperature swings can make the leaves wilt or fall.

nutrition

Spring to early autumn

Feed about once a month while your Nerve Plant is putting out new leaves. Use a balanced liquid houseplant fertiliser diluted to half the label strength, applied to already-moist compost.

Dilute rather than feed heavily—Fittonia’s fine roots are easily stressed by fertiliser salts.

Balanced nutrition

A general-purpose fertiliser with roughly even NPK supports leafy growth without pushing soft, weak stems. Do not feed a wilted, dry, or recently repotted plant; water first and let it settle.

Winter rest

Stop feeding in winter, or feed very lightly only if the plant is actively growing in bright, warm conditions. Resume when growth picks up in spring.

White crust on the soil, brown leaf edges, or sudden decline after feeding can signal excess salts. Flush the pot with plain water and pause fertiliser for a few weeks.

soil

Moisture-retentive, airy soil

Fittonia grows along the humid forest floor, where organic debris holds moisture while air still reaches its fine roots. Use a light houseplant mix that stays evenly damp but drains freely; avoid dense garden soil or mixes that remain waterlogged.

Slightly acidic is ideal

A pH of about 5.5–6.5 suits this plant well. Most peat- or coco-based houseplant mixes fall in this range.

Simple mix

Combine two parts quality potting mix with one part perlite or pumice. Add a small handful of fine orchid bark if the mix feels heavy, especially in a pot without much airflow.

After watering, excess water should run out promptly, while the mix still feels lightly moist a few days later.
