Check these first
- Check the soil moisture at a depth of 3 inches.
- Look for signs of standing water near the trunk.
- Observe if the yellowing is uniform or just between the veins.
Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow and may feel soft or limp. The soil around the base stays soggy for days after watering.
What to do: Wait until the top 3 inches of soil are dry before watering again. Ensure the planting site has good drainage and is not sitting in a low spot.
Nutrient deficiency
PossibleHow to tell: The leaves turn yellow while the veins remain green, often starting on older growth. This happens when the soil lacks nitrogen or iron.
What to do: Apply a balanced, slow release fertilizer in early spring. If the soil pH is too high, you may need to add organic matter to help the tree absorb nutrients.

When to worry
If the yellowing is widespread or happens during the peak of summer, it needs attention. A few yellow leaves in late autumn are just the tree preparing for winter.
Stopping it coming back
Water deeply every 7 to 14 days rather than giving small sips. Mulch around the base to keep soil moisture consistent without waterlogging the roots.

Questions people ask
- How much water does a mature tree need?
- Once established, it needs a deep soaking every 7 to 14 days during dry spells. Avoid frequent, shallow watering.
- Can I fix yellow leaves with fertilizer?
- Only if the soil is actually deficient. If you overwater, fertilizer will not help and might actually stress the roots further.
