Nerve Plant
Fittonia Albivenis

Everything it needs
9 essentials at a glance
Watering
Fittonia albivenis prefers consistently moist soil, so water when the top inch of soil feels dry.
During the growing season (spring and summer), water every 1-2 weeks, adjusting frequency based on humidity levels. In fall and winter, reduce watering to every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and leaf drop.
Light
This plant thrives in bright, indirect light but can tolerate low light conditions.
Avoid direct sunlight as it can scorch the leaves. Ideally, place it near a window with filtered light for about 6-8 hours a day, and ensure it has some shade during the hottest part of the day.
Soil
Fittonia prefers a well-draining potting mix that retains some moisture.
A mix of peat moss, perlite, and orchid bark works well, with a pH range of 5.5 to 6.5. Ensure the pot has drainage holes to prevent waterlogging.
Humidity
Fittonia thrives in high humidity levels of 60% or more.
To increase humidity, consider using a pebble tray with water or a humidifier. Signs of humidity stress include browning leaf tips and wilting. If humidity is too low, mist the leaves regularly.
Temperature
The ideal temperature range for Fittonia is between 65-80°F (18-27°C).
It is not frost-tolerant and should be kept in a warm environment, ideally in USDA hardiness zones 10-12. Protect it from cold drafts and sudden temperature changes.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 20-20-20, diluted to half strength.
Fertilize every 4-6 weeks during the growing season (spring and summer) and reduce feeding in fall and winter. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune Fittonia in spring to encourage bushier growth and remove any dead or damaged leaves.
Use clean, sharp scissors or pruning shears. You can also pinch back the tips of stems to promote branching. Deadheading is not necessary as this plant is primarily grown for its foliage.
Repotting
Repot Fittonia every 1-2 years or when it becomes root-bound.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include roots growing out of the drainage holes or stunted growth. To repot, gently remove the plant from its pot, loosen any tightly bound roots, and place it in fresh potting mix.
Propagation
Fittonia can be propagated through stem cuttings.
Take 4-6 inch cuttings from healthy stems, remove the lower leaves, and place them in water or a moist potting mix. Cover with a plastic bag to maintain humidity. Roots should develop in 2-4 weeks. The best time for propagation is in spring or early summer.

Care through the year
Spring
In spring, increase watering frequency as the plant begins to actively grow. Consider repotting if it has outgrown its pot.
Summer
During summer, maintain high humidity and provide bright, indirect light. Water regularly to keep the soil consistently moist.
Fall
In fall, gradually reduce watering as growth slows. Monitor humidity levels as indoor air can become drier.
Winter
In winter, reduce watering to every 2-3 weeks. Keep the plant in a warm location away from cold drafts.
Toxicity & Safety
Fittonia is non-toxic to pets and children, making it a safe choice for homes with animals. However, ingestion of large amounts may cause mild stomach upset.
