How do I get rid of this tree forever?
I have a bed we will be developing where there was (last year) what I think is a balsam poplar. One of the worst trees in the world! The main tree is gone, stump has been ground out. But little trees are now sprouting from the roots.
This is not unusual with this tree, I have five more of these trees and they all have sprouts coming up from the roots on "knees". I have to clip the sprouts a couple of times per month or they become trees themselves. Other than their sticky flower pods, cottonwood seeds and the knee problem, they are beautiful shade trees, well over 50 feet tall.
But I really want a garden where the tree above was removed. Is there any way to KILL these sprouts so I can plant in this bed?
