Pinstripe Calathea · Calathea ornata

Why does my Pinstripe Calathea have spots on its leaves?

Spots on a Pinstripe Calathea are less common than other issues and usually point to environmental stress or fungal infections. Check your water quality first, as these plants are very sensitive to minerals found in tap water.

Check these first

  1. Check if you are using tap water.
  2. Inspect the undersides of leaves for pests.
  3. Feel the soil to see if it stays soggy.

Likely causes

  1. Mineral buildup

    Most likely

    How to tell: You will see brown or yellow spots with a yellow halo, often appearing on the leaf edges or tips. This happens when salts and chlorine from tap water accumulate in the soil.

    What to do: Switch to using distilled, filtered, or rainwater for all your waterings. Flush the soil thoroughly with clean water once a month to wash away any remaining mineral salts.

  2. Fungal leaf spot

    Possible

    How to tell: These spots are usually dark brown or black, circular, and may have a fuzzy texture or a yellow ring around them. They often appear when the leaves stay wet for too long after misting.

    What to do: Stop misting the leaves immediately to keep the foliage dry. Remove any heavily infected leaves with clean scissors and improve air circulation around the plant.

When to worry

Worry if the spots are spreading rapidly or turning mushy. A few tiny spots on older leaves are usually just a sign of minor water quality issues.

Stopping it coming back

Use only filtered or distilled water and keep the leaves dry by avoiding overhead watering or misting.

Questions people ask

Can I use tap water if I let it sit out?
Letting tap water sit out helps remove chlorine, but it does not remove fluoride or heavy minerals. It is best to use distilled water for this sensitive plant.
Should I cut off the spotted leaves?
You can trim off leaves that are mostly brown or unsightly. Use sharp, clean scissors and cut close to the base of the stem.
