Some jobs test your planning and decision-making. 🌿
About six months ago I was called to manage a severe Leucaena infestation that had been spreading unchecked for years. The front yard — roughly 50m² — was heavily established with mature trees and mixed invasive species including to***co and Gamba Grass.
Leucaena is declared invasive in parts of Queensland for good reason. Deep taproots, aggressive regrowth, and the ability to thrive in poor soils make it difficult to control once established.
Before beginning, I assessed the site and treatment options carefully. For mature growth, two primary methods are generally considered:
• Basal bark treatment
• Cut-stump application
Each method has specific timing and application requirements. Based on site conditions and risk management considerations, I selected a controlled hybrid approach — reducing the growth to manageable size before applying targeted herbicide treatment to ensure effective uptake.
Appropriate protective equipment and safe handling procedures were used throughout the process.
The result: successful treatment and strong signs of dieback on follow-up inspection.
Invasive species management isn’t about “cutting it down.” It requires correct identification, method selection, timing, and follow-up monitoring.
If you’re dealing with established invasive growth in Logan or surrounding areas, it’s worth having it assessed properly.
