Chicago garden needs to have "tree of heaven" killed

What article?

Look at the "cut stump" method in the following link. You can use Brush B-Gon, full strength, when you can't find the Garlon:

Just chop it down like any other tree. They do spread a lot of seeds like any other tree and these trees can literally grow in a sidewalk crack but they aren't that big of a problem. I pull just as many maple seedlings as I do tree of heaven seedlings. I let one grow from seed and after 7 years it's 25 feet high making for a great shade tree. I trim if every fall to control and shape its growth because if you don't, it will grow like a weed because it is a weed.
