To offset fluoride in houseplants, use bottled water occasionally

Easter lilies are among the plants
susceptible to fluoride damage.
Q: Which houseplants are sensitive to fluoride from city water? I have a few plants with brown leaf tips and perhaps need to water them with bottled water. — Garden Information Line caller A: Not only is municipal water a source of fluoride but so is perlite — the white, spongy material in many potting mixes. Some fertilizers also might release enough fluoride to harm plants.
Cast-iron plants, dracaena, Easter lilies, freesias, parlor palms, peace lilies, prayer plants and spider plants can show symptoms of leaf-tip burn (browning) from fluoride.

It’s probably not necessary to water all the time with bottled water; just flushing the soil occasionally with rainwater or bottled water helps to reduce fluoride salt buildup.
