Why does my coffee plant have brown spots?

Brown or black spots on coffee plant leaves are often a sign of a fungal infection caused by too much moisture on the foliage. Check your watering habits and airflow to stop the spread.

Check these first

  1. Check if the soil is soggy or waterlogged.
  2. Look at the leaves to see if they stay wet after misting.
  3. Ensure the plant has good air circulation.

Likely causes

  1. Fungal Leaf Spot

    Most likely

    How to tell: Small, dark spots appear on the leaves, sometimes with a yellow halo. This thrives when leaves stay wet for too long.

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

  2. Overwatering

    Possible

    How to tell: Spots appear alongside yellowing leaves and soft, mushy stems. The soil stays wet for too long after watering.

    What to do: Allow the top inch of soil to dry out completely before watering again. Ensure your pot has drainage holes so excess water can escape.

When to worry

If the spots are spreading rapidly across the entire plant, it is a serious fungal issue. A single spot is usually manageable.

Stopping it coming back

Water only the soil, not the leaves, and keep the plant in a spot with good airflow.

Questions people ask

Should I use a fungicide?
Usually, removing the infected leaves and fixing the environment is enough. Fungicide is a last resort for severe cases.
Is it okay to mist the leaves?
It is better to avoid misting if you see spots. Use a pebble tray instead to keep humidity up without wetting the foliage.
