Check these first

- Check if the spots are mostly on the lower, inner branches.
- Look for fallen leaves on the ground.
Likely causes
Fungal leaf spot
Most likelyHow to tell: Small brown or black spots appear on the leaves, sometimes with a yellow halo around them.
What to do: Rake up and dispose of all fallen leaves under the tree to remove fungal spores. Prune away heavily infected branches to improve airflow through the canopy.
Poor air circulation
PossibleHow to tell: The inner leaves stay damp for too long after rain, leading to fungal growth.
What to do: Thin out crowded branches to allow sunlight and wind to reach the center of the tree. This helps the foliage dry out quickly after rain.

When to worry
Leaf spot is mostly cosmetic and rarely fatal. You should only worry if the tree loses a significant portion of its leaves before autumn.
Stopping it coming back
Water at the base of the tree rather than overhead to keep the leaves dry. Keep the area under the tree clean of debris throughout the growing season.
