As winter approaches, the beauty of snow-covered landscapes and the festive holiday season bring a sense of tranquility. However, winter also poses several challenges for trees, which can suffer from various forms of damage during the colder months.
1. Winter Desiccation: One of the most common issues trees face during winter is desiccation, a process in which the tree loses more water than it can absorb. This occurs when the ground is frozen, preventing the tree’s roots from taking up water, while the cold winds continue to draw moisture from the leaves.
What you can do to help your trees:
- Mulching around the base of the tree can help retain soil moisture.
- Anti-desiccant sprays can be applied to evergreen trees to reduce water loss through their needles.
2. Winter burn on Evergreens: Evergreen trees, such as pine and spruce, are susceptible to a condition known as winter burn. This occurs when the sun and wind cause excessive water loss, leading to the browning of needles.
What you can do to help your trees:
- Wrapping trees with burlap during the winter can provide protection against harsh winds.
- Planting evergreens in locations with some protection from winter winds can reduce the risk of winter burn.
3. Snow and Ice Damage: Accumulation of heavy snow and ice on tree branches can lead to breakage and structural damage. This can be particularly hazardous for trees with weak or overextended branches.
What you can do to help your trees:
- Proper pruning in the fall can help by removing weak or dead branches.
- Shaking snow off branches after a snowfall can prevent excessive buildup.
4. Animal Damage: In winter, animals may gnaw on tree bark or eat buds, causing significant harm. This is especially true when food sources are scarce.
What you can do to help your trees:
- Wrapping tree trunks with hardware cloth or plastic tree guards can deter animals.
- Providing alternative food sources for wildlife can help protect trees.
5. Salt Damage: Road salts used for de-icing can have detrimental effects on nearby trees by causing soil compaction and disrupting nutrient absorption.
What you can do to help your trees:
- Avoid using excessive amounts of salt near trees.
- Rinse tree roots with water in early spring to flush out accumulated salts.
Understanding the various types of winter tree damage and implementing preventive measures is crucial for maintaining the health and beauty of your trees. By taking proactive steps, you can help your trees withstand the challenges of winter and ensure they thrive come spring. Have one of our arborists come by and asses your trees.
