water quality and Ferns
Quick answer
If water quality is what's going on with your Ferns, the most likely cause is: Ferns (specifically Nephrolepis and Adiantum) are sensitive to chlorine, fluoride, and dissolved mineral salts found in municipal tap water. These chemicals accumulate in the leaf tips, causing marginal necrosis and stunted growth due to cellular toxicity (PMID 8812302).
Start here:
- 1. 1. Let tap water sit in an open container for 24-48 hours to allow chlorine to dissipate.
- 2. 2. Flush the soil monthly with distilled water to remove mineral salt buildup.
