Fittonia, also known as the Nerve Plant or Mosaic Plant, is a captivating houseplant celebrated for its striking foliage. Its deep green leaves are intricately veined with contrasting colors like white, pink, or red, creating a mosaic-like appearance. Originating from the tropical rainforests of South America, this low-growing perennial adds a vibrant touch to indoor spaces and is a popular choice for its distinctive patterns and compact growth.
Fittonia Care
Light
Fittonia thrives in bright, indirect light. An east or north-facing window, or a diffused south-facing window, provides ideal illumination. Direct midday sun can scorch their delicate leaves, causing yellowing or browning. Insufficient light may cause the vibrant veining to fade and result in leggy, sparse growth.
Watering
Consistent moisture is crucial for Fittonia, which wilts dramatically when thirsty. The soil should remain consistently moist but never waterlogged, as this can lead to root rot. Water when the top inch of soil feels dry. If the plant droops, it indicates extreme thirst and will revive quickly after a thorough watering.
Humidity
Fittonia requires high humidity, ideally 50% or higher. Low humidity can cause leaves to become crispy or develop brown tips. To increase humidity, use a pebble tray, mist regularly, or place a room humidifier nearby. Grouping Fittonia with other plants also helps create a more humid microclimate.
Soil
A well-draining potting mix that retains some moisture is ideal for Fittonia. A peat-based potting soil works well, often benefiting from added perlite, vermiculite, or orchid bark to enhance drainage and aeration. This mix provides consistent moisture without oversaturation. Ensure the pot has adequate drainage holes.
Temperature
Fittonia prefers warm, stable temperatures, ideally 60°F to 85°F (15°C to 29°C). They are sensitive to sudden temperature fluctuations and cold drafts, which can cause stress and leaf drop. Avoid placing them near drafty windows, air conditioning vents, or heating sources. Consistent warmth promotes healthy growth.
Fertilizing
During the active growing season (spring and summer), Fittonia benefits from regular fertilization. Use a balanced liquid houseplant fertilizer, diluted to half strength. Apply this solution every two to four weeks. Reduce or cease fertilization during fall and winter when growth slows.
Common Fittonia Problems
Wilting Leaves
Wilting in Fittonia is most commonly a sign of underwatering. The plant’s leaves will dramatically droop, but often recover quickly after a thorough watering. Less commonly, persistent wilting can indicate overwatering leading to root rot, where the roots are unable to absorb water. Checking soil moisture helps differentiate between these two issues.
Browning Leaves
Browning leaf tips or edges often signal a lack of humidity or inconsistent watering. Dry air causes the leaf margins to crisp. Too much direct sunlight can also lead to scorched, brown spots. Adjusting humidity and watering can alleviate this issue.
Leggy Growth
Sparse, stretched-out stems with fewer leaves, known as leggy growth, typically indicate insufficient light. When Fittonia does not receive adequate bright, indirect light, it will stretch towards a light source. Moving the plant to a brighter location and occasionally pinching back stem tips can encourage a fuller, more compact habit.
Pests
Fittonia can attract pests like spider mites, which cause yellowing leaves and webbing. Mealybugs appear as small, white, cottony masses, often in leaf axils. Aphids are small, soft-bodied insects that cluster on new growth, causing distortion. Regular inspection and wiping leaves with a damp cloth or applying insecticidal soap can manage infestations.
Propagating Fittonia
Fittonia is readily propagated from stem cuttings. Select a healthy stem section 2 to 4 inches long with a few leaves. Make a clean cut just below a leaf node, where new roots emerge. Remove any lower leaves that would be submerged.
Insert the cut end into a moist, well-draining rooting medium, such as peat-based potting mix or water. Covering the pot with a clear plastic bag or placing it in a terrarium helps maintain high humidity for rooting. Keep the medium consistently moist and place the cutting in a warm spot with bright, indirect light. New roots typically develop within two to three weeks.
