- Test the soil pH if the tree is in a lawn area.
Likely causes
Poor Drainage
PossibleHow to tell: The soil stays soggy for days after rain or watering. You might notice a sour smell near the roots.
What to do: Improve the soil drainage by adding organic matter like compost around the drip line. Avoid adding extra water until the top 3 inches of soil feel dry.
Nutrient Deficiency
PossibleHow to tell: Leaves turn yellow while the veins remain green. This often happens in very alkaline soil.
What to do: Test your soil pH to see if it is too high. Apply a balanced fertilizer formulated for trees if a soil test confirms a nutrient shortage.

When to worry
Worry if the yellowing spreads rapidly across the entire canopy. A few yellow leaves in late summer are just part of the natural aging process.
Stopping it coming back
Ensure the tree is planted in well draining soil and avoid overwatering during the first few years of establishment.
