How do you kill nandina bushes?

To kill nandina bushes, you can apply a non-selective herbicide containing glyphosate directly to the leaves or stems, ensuring thorough coverage. Alternatively, you can cut the bushes back to the ground and then apply an herbicide to the freshly cut stumps to prevent regrowth. For a more natural approach, you can dig out the roots completely. Be sure to follow all safety instructions and local regulations when using herbicides.
