Q&A – Can you kill black locust plants with hack and spray?

Question:
Can you kill black locust plants with hack and spray?
​​
Answer:

Yes you can. University of Memphis Director of Landscape Joellen Dimond says black locusts are easiest to control when they are small when you can easily pull them up. UT Extension Agent Chris Cooper says when you cut the trunk of the tree paint it with glyphosate or triclopyr that will get taken to the roots and kill the plant. It won’t be a one-time thing. You will need to eliminate any new shoots that come up from the roots.
