Pin Oak Borers and Planting Depth Issues

2-year-old pin oak (4" trunk, 15'): late bud break, small leaves. Tiny insect borer holes with sawdust trail on trunk.

Immediate: Borer Spray

Spray with borer insecticide (Fertilome recommended) from garden center.

Underlying Concerns

• Burlap not rotted: Dig and remove if present.
• Planted too deep: Root flare must be at ground level. Deep planting causes failure.

If Planting Issues Exist

Replant correctly. Fertilize with 13-13-13 at 2 lbs for this tree.

Outlook

Borers attack stressed trees. Fix planting depth/burlap + fertilize + spray for best recovery.
