How do you kill mugo pine?

To kill a mugo pine, you can apply a systemic herbicide containing glyphosate directly to the foliage or cut the tree down to the stump and then apply the herbicide to the freshly cut surface. Ensure you follow the manufacturer's instructions for application rates and safety precautions. Alternatively, you can smother the tree by covering it with a tarp or black plastic to block sunlight, but this method may take longer. Always check local regulations regarding herbicide use and disposal.
