How late should you water in the fall? Trees and shrubs that are not fully hydrated in the fall are prone to winter desiccation. During winter, photosynthesis is slowed down but deciduous plants still lose water through exposed bark, twigs and buds. Evergreen trees and shrubs lose water at a higher rate through their foliage. A deep watering once a month in the fall until the ground freezes can help the plant survive winter conditions.
