Summary

Tree of heaven is a highly invasive Asian tree that spreads quickly in Tennessee through huge seed crops and aggressive root sprouts, especially after soil disturbance. It forms dense thickets and can suppress other plants through allelopathy. Because cutting, mowing, or burning often triggers more sprouting, effective control focuses on killing the root system with systemic herbicides. Recommended methods include hack and squirt or cut stump treatments on large trees, basal bark sprays on small stems, and foliar sprays on seedlings and saplings, followed by ongoing monitoring and retreatment.
