Trees are living organisms that can get sick, just like people. When a tree becomes infected, the disease doesn’t stay in one spot. Left untreated, infections can spread to other trees, shrubs, and even compromise your property. Read this blog post to learn how tree infections spread and what you can do to protect your garden and keep your trees healthy.
How Tree Infections Spread
Tree infections can be caused by fungi, bacteria, or viruses, and they often move in ways you might not expect:
- Some infections travel underground, moving from one tree to another through interconnected root systems.
- Beetles, aphids, and other insects can carry spores or bacteria from infected trees to healthy ones.
- Fungal spores can be carried by the wind or splashed by rain onto nearby trees, starting new infections.
- Pruning tools, machinery, or even shoes can unintentionally transfer disease from one tree to another.
Signs Your Tree Might Be Infected
- Discoloured, wilting, or curling leaves
- Unusual growths like cankers, mushrooms, or knots on the trunk
- Dead branches or thinning foliage
- Sticky sap, ooze, or other unusual secretions
What You Can Do to Prevent the Spread
- Remove affected areas carefully, and disinfect your tools between cuts.
- Keep insects under control to reduce the chances of disease spreading.
- Avoid overcrowding so air can circulate and reduce fungal growth.
- Check your trees frequently for early signs of disease.
- A certified arborist can assess the situation, treat infections, or remove seriously infected trees safely.

FAQs
Can a tree infection spread to other plants in my yard?
Yes. Many tree infections, especially fungal diseases, can spread to nearby trees and shrubs if not treated promptly.
How do I know if a tree can be saved?
A certified arborist can inspect the tree, identify the disease, and determine if treatment is possible or if removal is the safest option.
Are all tree infections visible above ground?
Not always. Some infections start in the roots or internal wood and may only show above-ground symptoms after significant damage.
How often should I have my trees checked for disease?
At least once a year, ideally during the growing season, or more often if you notice changes in leaf colour, branch health, or overall tree vitality.
Is it safe to remove an infected tree myself?
Removing an infected tree can be dangerous, especially if it’s large or near structures. Professional tree removal ensures safety and prevents the spread of disease.
