I killed a locust tree by accident. Can I save it? It is turning yellow and it is not a yellow locust. I goofed on my wide leaf spray once and I must have doubled it. I sprayed near the tree for weeds. I really feel bad about it. I am no longer using sprays. Was it because I used my 80 year old brain? Dumb. Our 10 year old locust trees are turning yellow and the leaves are withering.
