I am searching for a way to get rid of these Tri Foliate Orange trees that have gone wild on my property in Goliad, Texas. Short of grubbing them out, cutting them down, and burning the stumps, we are at a loss. Is there anything that will kill them out. We have 10 acres and they are a real problem. It is very hard to get near enough to them to cut them down. Lately we have been pushing them over with the tractor and burning them. We would like to find something we could spray on them to kill them off. Thanks for any help anyone can give.
