What Is Tree Girdling?
Tree girdling occurs when something—be it overgrown roots, man-made objects, or animal activity—creates a constriction around the tree’s trunk or around its roots, restricting the tree’s ability to transport water and nutrients between the roots and the canopy. This damage disrupts the tree’s vascular system and can lead to severe health issues or death if not addressed.
Picture a tightly wrapped string cutting into the bark of a growing tree. Over time, this “stranglehold” prevents the tree from growing properly, making it weaker and more vulnerable to disease and environmental stressors. While the concept is simple, its consequences are dire.
Common Causes of Tree Girdling
Knowing the root cause of girdling is the first step to solving and preventing it. Here are the most common culprits:
Improper Planting Techniques
Planting a tree too deeply or failing to spread its roots evenly when planting can cause roots to circle around the trunk, eventually leading to girdling roots that restrict essential growth.
Landscape Materials
Objects such as stakes, wire, ties, or tree guards left in place for too long can eventually dig into the tree’s outer layers, causing girdling as the tree grows around them.
Natural Root Growth
Some tree species, like maples or lindens, naturally develop circling roots if their growth is restricted by hard soil, compact spaces, or shallow planting areas.
Animal Activity
Small animals, such as rodents or rabbits, can chew through bark at the base of a tree, thus creating a severed “belt-like” damage that ultimately disrupts nutrient transport.
Damage from Lawn Equipment
Repeatedly hitting a tree’s bark with lawnmowers or string trimmers might not seem like a big deal initially, but over time, this damage can mimic the effects of traditional girdling.
