Landscape Spike in Oak Root: Leave It Alone

A 12-inch landscape spike driven 3 inches into a large oak/hickory root 35-90 feet tall should be LEFT IN PLACE — removal causes more damage than the nail itself.

Why Leave It

Nail is inert: Steel doesn't poison trees.
Removal wound: Pulling it creates fresh entry for pathogens.
Tree compartmentalizes: Oak walls off the tiny injury naturally.

Real Concern: Root Heave

Oak/hickory roots expand annually — may lift landscape border in 5-10 years.
Not a maple (which heaves aggressively) — slower, less dramatic.
Monitor border — reset if lifting occurs.

No Medication Needed

Tree wound dressings, paints, sealants are obsolete — they trap moisture and promote decay. Trees heal best unaided.

The nail is trivial to a 90-foot oak. The border heave is the real long-term issue.
