What causes brown tips on houseplants?

It depends on the plant and how it is kept, so check the plant pages below. For Chlorophytum Comosum, the records explain it like this: Spider plants (Chlorophytum comosum) exhibit marginal leaf necrosis (brown tips) primarily due to fluoride and chlorine toxicity from municipal tap water. These halogen ions accumulate in leaf margins over 2-4 weeks, disrupting cellular metabolism and causing tissue death at the leaf apex. Unlike overwatering damage which affects entire leaves from the base upward, fluoride burn is restricted to leaf tips and margins.

Common first steps

  1. Switch to filtered, distilled, or rainwater for all watering
  2. Water the plant freely during the active growing season so the potting mix stays consistently moist, then check it daily in warm rooms because ctenanthes cycle through water quickly in summer.
  3. When the leaf edges first begin to brown, increase humidity around the foliage by misting or by standing the pot on a tray of damp pebbles, and never let the mix go fully dry between waterings.

snake plant, boston fern, calathea, spider plant, aloe vera and 105 others.

Can brown tips be prevented?

Use only filtered, distilled, or rainwater for all irrigation. Maintain 50-60% humidity. Fertilize at 1/4 strength monthly during growing season only—excess salts exacerbate tip burn. Test tap water with TDS meter; values >300ppm indicate high mineral content unsuitable for spider plants.
