Killing a healthy willow tree

Question

We need to kill a healthy willow tree that’s approx 30ft high. We can’t cut it down so need to be able to destroy it were it stands.

Answer 1

Since the tree is so large, you may want to consult with an arborist to prevent the possibility of having the tree fall once it's dead, or even have a professional come in a take the tree out. That being said, other than cutting the tree down, the suggestions in this article may help: https://www.gardeningknowhow.com/ornamental/trees/tgen/how-to-kill-a-tree-killing-trees-in-your-garden.htm
