In this Wednesday episode of Talking Trees, we dig into the science and practice of tree injections, also known as vegetative endotherapy. This method of delivering substances directly into a tree's vascular system is transforming plant care, especially in managing pests and diseases.

We explore:

• The history and development of endotherapy techniques
• Types of injection systems: trunk opening, interface, and direct injection
• The most common uses: applying insecticides, fungicides, and nutrients
• Practical considerations such as dosage, tree species suitability, and seasonal timing
• Benefits and limitations of injections compared to foliar sprays and soil treatments

With insights from recent research, this episode highlights how tree injections are emerging as a sustainable, targeted approach in arboriculture and urban forestry.
