Dragon tree · Dracaena

Why does my Dracaena have spots on its leaves?

It is less common for a Dracaena to develop spots, which usually points to mineral buildup from tap water or fungal issues from high humidity. Check your water source first to see if chemicals are the culprit.

Check these first

  1. Check if you are using tap water.
  2. Look for signs of pests like spider mites.
  3. Inspect the leaves for fuzzy growth.

Likely causes

  1. Fluoride sensitivity

    Most likely

    How to tell: Brown or yellow spots appear on the leaf tips and margins, often with a yellow halo.

    What to do: Switch to distilled or filtered water to avoid fluoride and chlorine. Flush the soil with clean water to remove accumulated salts.

  2. Fungal leaf spot

    Possible

    How to tell: Small, dark, circular spots with yellow borders appear on the leaves.

    What to do: Remove the affected leaves to stop the spread. Improve air circulation around the plant and avoid getting water on the leaves when you irrigate.
