If your Fittonia, also known as nerve plant, is turning yellow, it can be concerning. Yellowing leaves often indicate underlying issues that need to be addressed promptly to keep your plant healthy and vibrant.
Common Causes of Yellowing Fittonia
Overwatering
One of the most frequent reasons for yellow leaves is overwatering. Fittonia prefers moist soil but does not tolerate waterlogged conditions. Excess water can lead to root rot, which hampers nutrient uptake and causes leaves to yellow.
Underwatering
Conversely, underwatering can cause the plant to become stressed and leaves to yellow and drop. Ensure your Fittonia receives consistent moisture without being soggy.
Inadequate Light
Fittonia thrives in bright, indirect light. Too much direct sunlight can scorch leaves, turning them yellow or brown. Insufficient light can also weaken the plant, leading to yellowing leaves.
Nutrient Deficiency
A lack of essential nutrients, especially nitrogen, can cause leaves to yellow. Regular fertilization during the growing season supports healthy, green foliage.
How to Cure Yellowing Fittonia
Adjust Watering Habits
Ensure you water your Fittonia when the top inch of soil feels dry. Use well-draining soil and pots with drainage holes to prevent water accumulation.
Improve Lighting Conditions
Place your plant in a location with bright, indirect light. Avoid direct sunlight, which can scorch leaves, and ensure it receives enough light to stay healthy.
Fertilize Properly
Feed your Fittonia with a balanced, water-soluble fertilizer every 4-6 weeks during the growing season. Follow the package instructions for proper dilution.
Maintain Proper Humidity and Temperature
Fittonia prefers high humidity and temperatures between 65-80°F (18-27°C). Use a humidifier or mist the leaves regularly to increase humidity.
When to Seek Professional Help
If yellowing persists despite adjusting watering, lighting, and fertilization, consult a plant specialist. Persistent issues may indicate root rot or pest infestations requiring expert intervention.
