What Causes Ash Trees To Lose Their Leaves?

Ash trees may lose leaves because of drought stress, improper irrigation, root injury, insect infestations, fungal diseases, nutrient deficiencies, soil compaction, or age-related decline. Determining the actual cause requires a professional evaluation because many problems produce similar symptoms.

When leaf loss is accompanied by yellowing foliage, dead branches, bark damage, thinning canopies, or reduced growth, the tree may need corrective treatment to prevent further decline.
