Fittonia is a lovely plant with delicately veined, deep green leaves. Although the most popular vein color is silvery white, you can also readily find fittonia with veins in pink, white, and green. They are available as trailing houseplants or low-growing creepers that are perfectly fit for terrariums or bottle gardens. As beautiful as they are, fittonia are difficult to raise as conventional houseplants; they require very high, constant humidity (typical to a terrarium), but cannot stand stagnant conditions. Fittonia also dislike strong, direct sunlight and will quickly suffer from burn.
Keeping your Fittonia Fit ;
Light: Indirect or dappled sunlight. They also thrive under fluorescent lights. Don’t expose to full sunlight.
Water: Plants should be kept constantly moist, with high ambient humidity. Mist frequently or grow in a tray with pebbles and water.
Temperature: Average (around 70ºF). They can tolerate temperatures down to the mid-60s or into the low 80s.
Soil: Fittonia can be easily grown in conventional, peat-based potting soil. Make sure it can retain moisture, but will not remain soggy.
Fertilizer: Feed during the growing season with a weekly dose of weak liquid fertilizer or with controlled-release fertilizer.
