During the growing season, many people avoid trees with leaf scars. What is leaf scar, and how do they affect trees? Should you worry about leaf scars?   

As the go-to arborist in Harper, the Rockoff Tree Solutions crew discusses leaf scars, how they form, prevention, and more.  

Understanding Leaf Scars  

The term “leaf scar” can mean two things. First, it can refer to a healed hole or tear on a leaf’s surface or edges, showing the plant’s ability to heal.  

Second, it can refer to the scar left behind when leaves fall off trees in the winter up north. You’ll find these scars on twigs and branches, and since each type of tree has a unique scar, people often use them to identify tree types.  

How Do Trees Get “Leaf Scar”  

Trees can develop leaf scars in many ways and at any point in their lifespan. Everything from a minor bump or animal damage to inclement weather and pest infestations can tear leaves and cause scarring. Leaf scars on native trees or plants may point to the presence of invasive species.  

Scars from fallen leaves come from an open wound where the stalk connects the leaf to the stem. 

Should You Worry About Leaf Scars?  

Most leaf scars won’t harm your tree. They often show the plant’s resilience, but you must inspect the extent of the damage. If the damage seems extensive, the damage might be worse than you realize. Call an expert to check anything larger than the odd mark. 

Don’t sweat about surface-level damage; the tree will recover. But if the damage reaches the vascular tissues, the chances of recovery decrease. In some cases, leaf scars could indicate a fungal infection. Either way, don’t hesitate to contact a certified arborist for expert advice and help.  

When buying plants for your yard, try to find a reputable nursery. Your local arborist can usually point you in the right direction. That way, you increase the chances of buying healthy plants.  

Don’t let blemishes put you off. Provided you follow proper planting procedures and invest in routine maintenance, you’ll have healthy trees and a beautiful yard. 

With leaf drop, trees form a scab in anticipation to prevent further damage.  

Leaf Scar Prevention  

Sheltering your tree from elements that may cause scarring can help prevent leaf scars. Try to keep pests and animals away and avoid relocating the tree. Remember, you can’t always prevent leaf scars completely.  

Consider the overall effects. The tree will often shed the leaf eventually, so before the leaf falls, your garden won’t lose its aesthetic appeal for too long.  

The Bottom Line  

Fortunately, you shouldn’t worry too much about leaf scar. It might alter a leaf’s texture or shape but won’t compromise the tree’s overall health.   

Nonetheless, always check leaf scars for signs of pests or disease. Check for signs of live insects. Some insects leave tiny larvae behind, which can leave a more distinctive track.
