As an expert arborist, one of the most common questions I get is, “How can I tell if my tree is healthy?” While each species is different, there are a few universal signs that indicate your tree is in good shape. Here’s what to look for:
1. Full, Vibrant Canopy
A healthy tree will have a full crown of leaves (or needles) that match the typical color and size for its species and season. Whether lush green in summer or changing colors in fall, the canopy should be evenly distributed with no large bare patches.
2. Strong Branch Structure
Look for well-spaced branches that grow in a balanced pattern. Branches should be firm and free from cracks or splits. Dead or hanging limbs could be a sign of disease, pest issues, or root problems.
3. Healthy Trunk
The trunk should be sturdy with no deep cracks, cavities, or signs of decay. Some textured bark is natural, but loose or falling bark, fungus growth, or oozing sap can indicate trouble.
4. Consistent Growth
New growth is a great indicator of tree health. Healthy trees push out new twigs, buds, and leaves annually. If you’re not seeing growth or the new shoots are smaller than usual, the tree may be under stress.
5. No Signs of Pests or Disease
Inspect the leaves and bark for holes, chewed edges, spotting, or mildew. While minor pest activity is normal, a heavy infestation or visible fungus could compromise your tree’s health.
Final Tip:
Healthy roots equal a healthy tree. While you can’t always see them, signs like a firm base, no exposed or girdling roots, and stable soil around the trunk suggest the root system is doing its job.
If you’re ever in doubt, have a certified arborist assess your tree. A routine inspection can catch early issues and help keep your trees thriving for years to come.
