Phoenix FAQ
Do I have to remove a tree-of-heaven on my property?
Not legally required in Arizona. The tree is regulated but not prohibited. Most experts and county extension agents recommend removal due to invasive spread and the risk of hosting spotted lanternfly.
How do I kill a tree-of-heaven?
Cutting alone fails because the tree resprouts aggressively. Use the hack-and-squirt method with triclopyr or glyphosate herbicide, or basal bark treatment, in late summer for best results. Contact AZ Extension for guidance.
