Q.How to Stop Suckers From Growing and Roots Coming Up
Two years ago I had an old Locust tree removed and stump grounded. Replaced it with red maple, but now the roots appear to be coming up and the yard is filled with suckers from the Locust. How do I get rid of the suckers and what do I do about the roots of the young maple pushing up above ground?
Depending on variety of maple, you may not be able to be root free above ground. Some maples have more prominent roots above ground than others.
As far as the locust is concerned, if it were mine, I'd purchase an herbicide with 2-4D as an ingredient. Immediately after cutting back a sucker, pour a couple tablespoons of herbicide over exposed stem. This should kill the sucker and any others along that particular root/rhizome.
