🔒 Wound Dressings
Subscriber-only episode
In this episode of Talking Trees, we explore the use of wound dressings in arboriculture and whether they truly benefit trees. For decades, arborists and tree care professionals have debated their effectiveness in preventing decay, promoting healing, and reducing infections.
We discuss:
- Tree wound response mechanisms – How trees naturally compartmentalize damage through the CODIT (Compartmentalization of Decay in Trees) model.
- Historical use of wound dressings – From tar-based sealants to modern synthetic coatings, what has research revealed about their impact?
- Scientific findings – Studies show that wound dressings often fail to prevent decay and can even trap moisture, creating a breeding ground for pathogens.
- Alternative approaches – How proper pruning techniques and tree physiology should be prioritized over artificial wound treatments.
Long-term research, including Shigo and Shortle’s 13-year study, suggests that leaving wounds untreated and allowing trees to naturally heal is the most effective strategy. However, certain special cases—such as protecting trees from disease transmission (e.g., oak wilt, Dutch elm disease)—may justify limited use of sealants.
Join us as we analyze the science behind wound dressings in tree care, separating fact from fiction and offering best practices for arborists and tree managers.
