Winter can be harsh on trees & shrubs, especially younger, tender plants and less cold-hardy species such as palms. Winter damage comes from 2 main causes: cold temperatures and drying winds. To protect trees (in particular, palm trees) from cold and the rot that can often result from it, cover them with a TreeHelp Cold Weather Blanket and spray with Liquid Copper Fungicide. To protect trees and shrubs from excessive moisture loss from drying winds, spray the foliage with Wilt-Pruf Anti-Transpirant.
