Some people understand that animals (like bears) will hibernate during the winter to avoid facing the cold and intemperate climate. Trees also experience a process similar to hibernation. It’s called “dormancy,” and it keeps them alive while Mother Nature throws freezing temperatures, ice, and wind at our outdoor friends… as Canadians hunker down by the fireplace. All the systems within a tree slow down as it begins to lose its leaves. During this process, a chemical called abscisic acid is produced in the terminal bud, causing a leaf to fall.
“Evergreens” (or pine trees with needles) are able to survive bitter cold winters and maintain their green appearance. The small and thin needles are covered in a waxy substance called “cutin.” They don’t require much water to stay alive and perform photosynthesis differently from an ordinary “leaf.” Amazingly, cutin also stops any water from freezing and killing pine needles.
Trees face two main challenges during Canadian winters: Cold and lack of water. If you have concerns for the trees on your property, consider calling for professional advice.
