So there’s a tree growing in my back yard and I really want to get rid of it: Its seeds are invading my lawn and normal weedkiller doesn’t kill them. I was hoping not just to cut it down and try and dissolve or dig up the roots, but actively kill it.
I had thought that cutting away the bark in a circle would prevent the leaves from receiving nutrients, but thus far it hasn’t seemed to make a difference. My sister-in-law said that copper nails would do the trick, but I’m not sure. I’ve thought about RoundUp, but haven’t tried it yet.
(This tree is more weed than tree. A plumber I talked to about its roots growing into my sewer line said that it’s actually illegal now to sell or buy them in California.)
