Fluoride Toxicity on dracaena
What's Happening
Dracaena species (including D. marginata, D. fragrans, and D. sanderiana) are highly sensitive to fluoride and chlorine in tap water. These minerals accumulate in leaf tips, causing brown, crispy margins and tips.
How to Fix It
- 1
Switch to filtered, distilled, or rainwater for all watering.
- 2
If using tap water, let it sit in an open container for 24-48 hours (allows chlorine to dissipate, though not fluoride).
- 3
Flush the soil thoroughly with distilled water to remove mineral buildup.
- 4
Trim brown tips with sterile scissors, following the natural leaf shape, but leaving a tiny sliver of brown to avoid re-opening the wound.
How to Prevent It
Exclusively use mineral-free water. Avoid perlite-heavy mixes if the perlite is not pre-rinsed, as it can contain fluoride. Flush soil monthly.
