Care at a glance

Light

Fittonia wants the spot a few feet back from a sunny window — bright enough to read a paperback at noon, but the sun never falls directly on the leaves. Bright indirect light; tolerates lower light. Direct sun scorches the leaves. A faint hand shadow at midday is the right amount; a sharp dark shadow means it's getting direct sun and probably too much.

Watering

Water fittonia when the top 1 cm of soil is dry, every 3-5 days. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Keep evenly moist. Wilting is a clear signal — a thorough watering revives it within an hour.

Soil and pot

Fittonia grows best in moisture-retentive houseplant mix. Standard potting compost; no special amendments needed. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Fittonia sits happiest at around 60-80% humidity and 18-26°C (65-80°F). Loves high humidity. A terrarium is its ideal environment. If you keep the room above 18 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed fittonia sparingly. Quarter-strength balanced feed every 4-6 weeks during the growing season. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on fittonia in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Dramatic wiltingSoil dried out completely; soak and the plant should recover within an hour.
  • Crispy leaf edgesLow humidity.
  • Faded vein colourToo much direct sun.
  • Leggy stemsPinch tips to keep the plant bushy.

Propagation

Stem cuttings root within 2-3 weeks in water or moist mix. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Fittonia is pet-safe. Fittonia albivenis is listed by the ASPCA as non-toxic to cats and dogs. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
