Remove diseased or dead branches from Japanese maples
Japanese maples are beautiful and delicate trees that require regular pruning to maintain their health and appearance. Removing diseased or dead branches is an essential part of this process.

- Clean the pruning tools. After pruning, clean your tools with a disinfectant to prevent the spread of disease.
- Dispose of the diseased or dead branches. Diseased or dead branches should be disposed of in a garbage bag or burned.

How to Prune a Japanese Maple Tree
Thin out the canopy of Japanese maples
Are your Japanese maple trees starting to look crowded or overgrown? Thinning out the canopy can help improve air circulation, sunlight penetration, and overall tree health. Here’s how:
Why thin the canopy?
- Improves airflow and reduces disease risk.
- Allows more sunlight to reach lower branches and the trunk.
- Enhances the tree’s natural form and aesthetics.
When to thin the canopy:
- Best done in late winter or early spring before new growth begins.
How to thin the canopy:
- Remove inward-growing branches that cross or rub against each other.
- Cut back branches that are growing too close together to create space.
- Remove branches with weak crotch angles, where two branches meet at a narrow angle.
Remember:
- Avoid removing more than 25% of the tree’s canopy at once.
- Leave the main branches intact, especially in upright trees.
- Use sharp, clean pruning tools for precise cuts.
Key Takeaways:
- Thinning the canopy improves airflow, sunlight penetration, and tree health.
- Do it in late winter/early spring before new growth emerges.
- Remove inward-growing, rubbing, or branches with weak crotch angles.
- Avoid removing more than 25% of the canopy at a time.
