European Beech · Fagus sylvatica

Why are there spots on my European Beech leaves?

It is less common for a European Beech to develop spots, as this usually points to fungal activity encouraged by high humidity or poor air circulation. Inspect the spots to see if they are fuzzy or if they have a distinct dark border.

Check these first

  1. Check if the spots are appearing mostly on the lower, inner branches.
  2. Look for lesions or cracks on the main trunk.
  3. Clear away all dead leaves from the base of the tree.

Likely causes

  1. Fungal Leaf Spot

    Most likely

    How to tell: Small brown or black spots appear on the leaves, often with a yellow halo. These spots may grow and cause the leaf to wither.

    What to do: Remove and dispose of any fallen leaves to prevent the fungus from spreading. Improve air circulation around the tree by pruning away crowded branches.

  2. Beech Bark Disease

    Possible

    How to tell: The spots are accompanied by sunken, discolored lesions on the bark. This is a serious condition caused by a fungus entering through scale insect wounds.

    What to do: Consult a professional arborist if you see sunken lesions on the trunk. Focus on keeping the tree vigorous through proper watering and avoiding bark damage.

When to worry

Worry if the spots are spreading rapidly or if you see lesions on the trunk. It is normal to see a few minor blemishes on older leaves toward the end of the season.

Stopping it coming back

Water at the base of the tree rather than overhead to keep the foliage dry. Keep the area around the tree clear of debris.
