Dealing with nuisance trees
In my newly acquired home I have found that 7 of the 11 trees in my small backyard are the infamous Tree of Heaven AKA Ghetto Palm AKA Stink Tree AKA Tree of Hell. More detail can be found http://en.wikipedia.org/wiki/Tree_of_heaven
The tree suckers vigorously, resprouts vigorously, deposits natural herbicides in to the ground and has various other antisocial behaviors.
I can take the smaller trees out, but the larger ones I can't tackle right away (probably not for another 3-4 months.)
One of the larger trees is close to my house. For the large trees can I minimize some of the antisocial suckering by girdling (ring barking) the tree? Presumably this should stop sugars from making it down in to the root system. Would it also stop resprouting? Will it stimulate extra suckering? Can I stop the extra suckering if I do ring barking plus glycophosphate (round-up herbicide) will that kill the tree right away and risk the tree falling over by itself in an uncontrolled way?
Let me know your opinions about what I should do to contain this pest.
