Dry air, low precipitation, little soil moisture, and fluctuating temperatures are characteristics of fall and winter in many areas of Colorado. Trees, shrubs, perennials and lawns may be damaged if they do not receive supplemental water. Susceptibility to damage increases for lawns, plants and trees with southern or western exposure. Also, newly planted trees and shrubs are most susceptible to winter drought injury.
Water only when the air temperatures are above 40 degrees F.
Apply water at mid-day to allow absorption before possible freezing at night
