Threats & Impacts:
These trees produce large quantities of seeds and exude chemicals from their roots that suppress the growth of surrounding plants. Tree-of-heaven’s incredibly rapid growth rate allows it to outcompete native species for space and resources.
Small seedlings can be removed by hand pulling or digging. Larger plants and infestations can be treated with triclopyr or a glyphosate-based herbicide. Foliar spray, cut stump, basal bark, and hack and squirt are all effective.
