Winter Moisture Treatment

winter burn evergreens

Evergreens including those with broad leaves (e.g., boxwood, holly, rhododendron), needles (e.g., fir, hemlock, pine, spruce, yew) and scale-like leaves (e.g., arborvitae, false cypress, juniper) are prone to the damaging effects of winter burn. Leaves and needles can dry out (desiccate) because the dry winter winds evaporate their moisture in spite of their wax coatings. The frozen soil also prevents the roots from absorbing water to help in moisture replacement.

Winter burn shows up as brown, red or orange, dry foliage or needles and becomes apparent as the snow melts and spring arrives. Some or all of the foliage may be affected, with areas on the sunny side most severely damaged. Trees by sidewalks, driveways and roads may show more damage from winter burn because airborne chloride particles in road salt settle on needles and breaks down their wax protection.

We apply a protective coating to the leaves and needles that reduces the amount of water that escapes during winter.
