Oak Tree Losing Inner Leaves: Normal Self-Pruning

An 18-year-old oak shedding leaves on small inner branches is simply self-pruning. Shaded interior twigs are jettisoned as the canopy expands. Outer crown foliage remains full—tree is healthy.

To Prune or Not?

Deadwood removal is purely aesthetic. Limbs will fall naturally. No health benefit either way. Enjoy the acorns and shade.
