Why does my elderberry have spots on its leaves?

Spots on elderberry leaves are often a sign of fungal issues caused by humidity or poor airflow. Check the leaves for a white, powdery coating to identify the most common culprit.

Check these first

  1. Rub the spots to see if they wipe off like dust.
  2. Check if the spots are concentrated on the lower, inner parts of the plant.
  3. Observe if the spots appear after a long rainy spell.

Likely causes

  1. Powdery mildew

    Most likely

    How to tell: You will see a white, dusty fungal growth on the surface of the leaves and stems. It often appears during humid or damp weather.

    What to do: Improve air circulation by pruning crowded branches. Apply a fungicide or a mix of one tablespoon of baking soda in a gallon of water to the leaves.

  2. Fungal leaf spot

    Possible

    How to tell: Dark or brown spots appear on the leaves, sometimes with a yellow halo around them. This usually happens after periods of heavy rain.

    What to do: Remove and destroy any infected leaves that fall to the ground to stop the spread. Avoid overhead watering to keep the foliage as dry as possible.

When to worry

Mildew is common in late summer and usually doesn't harm the plant's long term health. Worry if the entire plant is covered and leaves begin to drop prematurely.

Stopping it coming back

Plant your elderberry in a spot with good sunlight and enough space for air to move through the branches. Water at the base of the plant rather than spraying the leaves.

Questions people ask

Should I cut off all the spotted leaves?
If only a few leaves are spotted, go ahead and remove them. If the whole plant is affected, focus on improving airflow instead.
Will these spots spread to my other plants?
Powdery mildew is easily spread by wind to other susceptible plants. Keep an eye on your nearby shrubs during humid weather.
