Spray your plants to save them. Winter is cruel to our plants. Harsh winds dry the leaves of the evergreens and hungry deer, rabbits and other varmints will eat almost anything they find. On warm dry days, you can spray evergreens with an anti-desiccant such as Wilt-Pruf that helps the leaves and needles retain moisture. A monthly spraying on another warm day with an animal repellent may prevent leaves and flower buds from disappearing into the stomachs of browsers.
