- Regularly inspect the fern for early signs of infection.
Effective Treatment Strategies

Prune and dispose of infected fronds carefully to prevent the spread of fungi. Use sterilized scissors and avoid damaging healthy tissue.
Applying Fungicides
Use a fungicide labeled for use on ferns, such as neem oil or copper-based fungicides. Follow the manufacturer’s instructions carefully and reapply as needed.
Improving Growing Conditions
Adjust watering practices, improve air circulation, and reduce humidity if possible. Ensuring optimal growing conditions can help your fern recover and prevent future infections.
When to Seek Professional Help
