Check these first
- Inspect the underside of the leaves for insects.
- Check if the leaves are staying wet for too long.
- Look for signs of mold or fungal growth.
Likely causes
Fungal leaf spot
Most likelyHow to tell: Small brown or black spots appear on the leaves, sometimes with a yellow halo. These spots may grow and cause the leaf to drop early.
What to do: Remove and destroy fallen leaves to reduce fungal spores. Improve air circulation around the tree by thinning out crowded branches.
Pest damage
PossibleHow to tell: Tiny yellow or brown spots appear where insects have been feeding on the leaf surface. Look closely at the underside of the leaves for small bugs.
What to do: Spray the foliage with insecticidal soap or neem oil. Repeat the treatment every 7 days until the pests are gone.

When to worry
Most leaf spots are cosmetic and won't kill the tree. Worry if the spots cover most of the foliage or cause massive leaf drop.
Stopping it coming back
Water at the base of the tree rather than overhead to keep leaves dry. Keep the area around the tree clean of debris.
