The only (somewhat) special treatment that Tree of Heaven would need for removal efforts to be effective is pre-treatment with a systemic herbicide, and then allowing the tree enough time (perhaps a month) to succumb to its affects before it's cut down. If cut too soon after treatment, or if the herbicide step was skipped, then sucker growth might be excessive for years to come. You can find more thorough details about control methods and their timing (calendar) in Penn State resources, which our page above links to.
