Why is my birch tree dying from the top down?
Birch trees can die from the top down due to an infestation by the bronze birch borer, which disrupts water and nutrient flow in the tree.
Symptoms of infestation include yellowing or wilting foliage that turns brown and drops, first appearing on upper branches.
If caught early, systemic insecticides can be applied at the base of the trunk to combat infestations.
Trader mulberry, which is hardy in colder climates, is increasingly available at local garden centers and is suggested for planting in the fall for better root growth.
