During the winter or dormant season, to what height should repellents be applied to protect trees?

• A. 6 feet above the expected maximum snow depth
• B. 3 feet above ground
• C. 9 feet above ground
• D. 1 foot above snow depth

Answer: (A)

Repellents used on trees in winter should be applied high enough that the treated area stays above the snow and within reach of herbivores. The standard recommendation is six feet above the maximum expected snow depth. This ensures the protective barrier remains visible and effective even as snow accumulates, drift forms, or shifts, and helps deter animals from reaching the trunk where bark damage occurs. If you apply too low, the snow can cover the treated area, making the barrier ineffective; applying higher than practical isn’t necessary because the goal is to cover the trunk where damage is likely while staying above the typical snow line. After heavy snowfall or thaws, recheck and reapply as needed to maintain protection.
