Designed to safeguard your landscape from winterkill symptoms and lessen water transpiration in December. When plants harden off after the first frost or the equinox in September, water conservation becomes an important health factor for trees and shrubs as they prepare for winter stress. Anti-desiccants can reduce water transpiration up to 85% during the winter months. Flower buds, evergreen leaves and needles, twigs, branches and whole plants can be protected from drought, extreme cold, high winds and lack of snow cover insulation. A second application is applied in mid-winter.
