How do you kill a princess tree?

To effectively kill a princess tree (Paulownia tomentosa), you can employ methods such as cutting it down and applying an appropriate herbicide to the freshly cut stump to prevent regrowth. Alternatively, you can girdle the tree by removing a strip of bark around the trunk, which disrupts its nutrient flow. It's essential to follow local regulations regarding tree removal and herbicide use, as well as to consider environmental impacts.
