Tap Water Burn on spider plant

spider plant with tap water burn

What's Happening

Spider plants (Chlorophytum comosum) are hypersensitive to chlorine and dissolved mineral salts in treated tap water. While fluoride causes marginal necrosis, chlorine causes generalized leaf tip browning and can bleach variegation. Municipal water treatment chemicals accumulate in soil over time, creating a toxic environment that manifests as progressive browning from leaf tips inward. Unlike fluoride damage (crispy brown), chlorine damage may appear as yellow-brown mottling.

How to Fix It

  1. 1

    Switch to rainwater, distilled water, or filtered water immediately

  2. 2

    If using tap water, let it sit 24-48 hours in an open container to off-gas chlorine

  3. 3

    Install a shower filter or carbon filter for plant watering

  4. 4

    Flush soil thoroughly with distilled water monthly to remove salt buildup

  5. 5

    Test tap water with TDS meter; readings above 300 ppm indicate high mineral content

How to Prevent It

Use only filtered, distilled, or rainwater for spider plants. Never use softened water (contains sodium). Test water quality seasonally as municipal sources vary.
