Yellow or brown leaves can result from several different conditions, including drought, excessive watering, nutrient deficiencies, insect damage, disease, or normal seasonal changes. Identifying the cause requires considering when symptoms appeared and how they are distributed throughout the canopy.
For example, widespread leaf yellowing may suggest root stress or a nutrient-related issue, while localized browning can sometimes indicate branch damage or disease. Leaf scorch may occur during hot, dry weather when a tree loses moisture faster than its roots can replace it.
Soil conditions are particularly important. Poor drainage, compacted soil, construction damage, and changes in irrigation can interfere with healthy root function. A tree may continue showing symptoms long after the original stress occurred.
