Introduction
Winter can be a tricky time to identify tree diseases. With leaves gone and trees dormant, the signs of trouble are often subtle. But catching problems early can make all the difference. Here’s how to recognize signs of disease during the colder months and what you can do to keep your trees healthy.
1. Bark Changes Can Signal Trouble
Peeling, cracking, or discolored bark often points to a bigger problem. These signs could indicate internal decay or a fungal infection.
How to Check:
Look closely at the trunk and branches for irregularities. If you spot extensive damage or areas that feel soft, it’s time to call a professional arborist.
2. Fungal Growth Is a Red Flag
Fungi like mushrooms or shelf-like growths at the base of a tree or on its trunk are strong indicators of decay.
What to Do:
While small fungal growths can be removed, they often signal more significant internal issues. Have an expert assess your tree’s condition.
3. Brittle Branches and Shriveled Buds
Healthy branches should be firm and flexible, while buds should appear plump and intact. If branches snap easily or buds look dried out, your tree might be struggling.
How to Check:
Gently bend smaller branches. If they snap or feel hollow, prune them to prevent further spread of disease.
4. Watch Evergreens for Needle Discoloration
Evergreens are active year-round, making them easier to monitor. Browning or yellowing needles can be a sign of root rot, fungal infections, or other issues.
How to Help:
Regularly inspect needles and water your evergreens during mild winter days if conditions are dry. If discoloration spreads, reach out to an arborist.
5. Keep an Eye on the Roots
Roots are the foundation of tree health, and winter stress can expose them to disease. Signs of trouble include soil erosion, exposed roots, or poor drainage near the tree.
What to Do:
Add mulch around the base to insulate roots and retain moisture. Be cautious about piling snow or using de-icing chemicals near the tree’s root zone.
Conclusion
Even in winter, it’s essential to pay attention to your trees’ health. By spotting signs of disease early—like bark damage, fungal growth, or brittle branches—you can take action to protect your trees and keep them thriving for years to come.
