Elderberry · Sambucus

Why does my Golden Elderberry have spots on its leaves?

Spots on your Golden Elderberry are usually a sign of a fungal issue caused by moisture sitting on the leaves. The most common culprit is powdery mildew, which creates a dusty look. Check if the spots are white and fuzzy or dark and sunken to identify the cause.

Check these first

  1. Rub the white spots to see if they wipe off like powder.
  2. Check if the spots are appearing mostly on the lower, older leaves.
  3. Ensure the plant has enough space from other shrubs for air to circulate.

Likely causes

  1. Powdery Mildew

    Most likely

    How to tell: You will see a white, dusty coating that looks like flour on the surface of the leaves. It often starts in late summer when nights are cool and days are warm.

    What to do: Prune away the most heavily infected branches to improve airflow. Apply a fungicide or a mixture of one tablespoon of baking soda in a gallon of water to the leaves.

  2. Leaf Spot Fungi

    Possible

    How to tell: These appear as dark, circular spots that may have a yellow halo around them. They often develop after periods of heavy rain.

    What to do: Remove and dispose of any fallen leaves around the base of the plant to stop the spread. Avoid overhead watering to keep the foliage dry.

When to worry

A few spots are normal in humid weather, but if the entire plant is covered or leaves are dropping, you need to treat it.

Stopping it coming back

Water at the base of the plant rather than over the leaves, and prune to keep the center of the shrub open.

Questions people ask

Is powdery mildew contagious to my other plants?
Yes, the spores can easily travel to nearby susceptible plants through the air.
Should I cut off all the spotted leaves?
If only a few leaves are affected, go ahead and remove them. If the infection is widespread, focus on improving airflow and using a treatment.
