    Watering a houseplant with the Pearl Roots filtered watering can
    QUICK ANSWER

    Filtered, rain or distilled water. This family reacts to chlorine, chloramine and fluoride with crisp brown edges, even in a humid room. You do not need pure water; you need water without those three, and filtered and remineralized water does that from the tap.

    The cause

    What calatheas react to

    Chlorine and chloramine, which stress their fine roots.

    Fluoride, left at the leaf edge.

    Softener salt, which is worse than hard water.

    Cold water. Use room temperature.
