Fittonia, also known as nerve plant, is a popular houseplant admired for its vibrant foliage. While fertilizing is essential for healthy growth, over-fertilization can harm your plant. Recognizing the signs early and knowing how to recover can save your Fittonia from lasting damage.
Signs of Over-fertilization in Fittonia
1. Leaf Burn and Browning Edges
One of the most noticeable signs is browning or scorching of leaf edges. This occurs because excess fertilizer salts accumulate in the soil and cause dehydration of leaf tissues.
2. Wilting and Drooping
Over-fertilized plants may appear wilted despite adequate watering. The excess salts can hinder water uptake, leading to a drooping appearance.
3. Yellowing Leaves
Yellowing leaves, especially on newer growth, can indicate nutrient imbalance caused by over-fertilization.
How to Recover Your Fittonia
1. Stop Fertilizing Immediately
Cease all fertilization to prevent further salt buildup. Wait until the plant shows signs of recovery before resuming any feeding.
2. Flush the Soil
Water the plant thoroughly with room-temperature water to flush out excess salts. Repeat this process several times, ensuring excess fertilizer is leached from the soil.
3. Improve Drainage
Ensure the pot has drainage holes and use well-draining soil. Good drainage helps prevent salt accumulation and promotes healthy root growth.
4. Adjust Watering Practices
Water only when the top inch of soil feels dry. Use distilled or rainwater if your tap water is high in minerals.
5. Monitor and Resume Fertilizing Carefully
After the plant shows signs of recovery, reintroduce fertilizer at half the recommended strength. Use a balanced, water-soluble fertilizer every 4-6 weeks during the growing season.
Prevention Tips
- Use a diluted fertilizer solution.
- Fertilize during the active growing season only.
- Regularly flush the soil to prevent salt buildup.
- Ensure proper drainage and avoid overwatering.
By paying attention to your Fittonia’s signs and adjusting your care routine, you can keep your nerve plant healthy and vibrant for years to come.
