hard water damage on Bromeliad
Quick answer
If your Bromeliad has hard water damage, the most likely cause is: Hard tap water contains calcium, magnesium, and chlorine that accumulate in the central cup and leaf trichomes over time. These mineral deposits block the foliar absorption pathways and create white crusts that prevent proper nutrient uptake. Chlorine and fluoride in municipal water also damage the sensitive leaf tissue adapted to pure rainwater.
Start here:
- 1. Use only distilled water, collected rainwater, or filtered reverse-osmosis water for cup filling
- 2. If tap water is only option: let sit 24 hours to off-gas chlorine, or boil and cool
