Pocket Botanist
Check these first
- Inspect the undersides of the leaves for fuzzy growth or spores.
- Check if the spots are concentrated on the lower branches where airflow is lowest.
- Observe how long the leaves stay wet after a rain or watering session.
Likely causes
Fungal Leaf Spot
Most likelyHow to tell: You will see small, dark, or discolored circles appearing on the foliage. These spots may grow larger or merge together as the infection progresses.
What to do: Prune away the most heavily affected branches to improve airflow through the canopy. Apply a copper based fungicide spray to the leaves every 7 to 10 days until the new growth looks healthy.
Overhead Watering
PossibleHow to tell: The spots appear shortly after you water the tree using a sprinkler or hose that wets the leaves. The foliage stays damp for too long, creating a perfect home for fungi.
What to do: Switch to a drip irrigation system or a soaker hose that delivers water directly to the soil. Always water early in the morning so any accidental moisture on the leaves evaporates quickly in the sun.

When to worry
Worry if the spots cover more than half of the leaf surface or if the tree begins losing foliage rapidly. A few minor spots are common during very wet, humid summers.
Stopping it coming back
Keep the area around the base of the tree clear of fallen leaves and debris to prevent fungal spores from overwintering. Ensure the tree is planted in a spot with plenty of direct sun and good wind circulation.

Questions people ask
- Will these spots kill my tree?
- Usually no, but they can weaken the tree if left untreated for a long time. Keeping the tree healthy with proper sun and water helps it fight off infections naturally.
- Should I remove all the spotted leaves?
- Remove the ones that are heavily damaged or dropping, but do not strip the tree bare. The tree needs its leaves to produce energy through photosynthesis.
