Anti-Desiccant

Anti-desiccant sprays are applied to plants in December/January to prevent water and moisture loss during the cold, dry winter months.

Per UMass: "Desiccation injury may occur when water is transpired or "lost" through plant tissue more quickly than it can be absorbed though the roots. This is caused by long dry periods of cold and thaw along with winter winds. Anti-desiccant sprays add a protective waxy coating to the leaves of broadleaf evergreens to help slow the process of transpiration."
