Once the ground freezes, plants will no longer be able to drink water from the soil. Water trees, shrubs, lawns, and perennials deeply into fall to help plants remain hydrated through the longer winter. Dry, cold weather will dry a plant out just as fast as the heat of summer. Winter damage to plants often happen because the plant is unable to draw water from the frozen earth. The result of long, dry periods during fall and winter is injury or death to parts of the plants’ root system. However, make sure to water only when air temperatures are above 40F (4.4C) by applying the water mid-day to give it time to soak in before freezing at night as ice on the lawn can suffocate the grass.
