Orange Jessamine · Murraya paniculata

Why does my Murraya paniculata have spots on its leaves?

It is less common for this plant to develop spots, which are usually caused by fungal issues related to pests like scale insects. Check the undersides of the leaves for small bumps or sticky residue first.

Check these first

  1. Look for sticky honeydew on the leaves.
  2. Check the stems for small, hard bumps.
  3. Examine the spots to see if they rub off.

Likely causes

  1. Sooty Mold

    Most likely

    How to tell: Black, powdery spots appear on the leaves, often covering the surface like dust.

    What to do: Wipe the leaves with a damp cloth to remove the mold. Treat the underlying scale insect infestation with neem oil or insecticidal soap.

  2. Fungal Leaf Spot

    Possible

    How to tell: Small brown or tan spots with yellow halos appear on the foliage.

    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.

When to worry

Worry if the spots are spreading rapidly across the entire plant. It is normal to see an occasional spot on an older leaf that is ready to drop.

Stopping it coming back

Keep the plant clean and monitor for scale insects to prevent the honeydew that leads to sooty mold.
