TL;DR
A House Beautiful report, citing a certified arborist and a horticulturist, advises homeowners not to simply cut down tree of heaven because damaged roots can produce new shoots. The experts describe stump treatment and repeated cutting as possible control methods, while warning that identification and impacts on nearby plants and soil matter.
A House Beautiful report citing a certified arborist and a horticulturist advises homeowners not to simply cut down tree of heaven, an invasive tree that can resprout from its roots after cutting. The experts describe stump treatment and repeated cutting as possible control approaches, but the report does not establish a single method as right for every property.

Tree of heaven, or Ailanthus altissima, is native to China. The report describes it as a fast-growing tree that can spread in a range of conditions. Certified arborist Logan Foltz of Urban Arborists says it can outcompete North American trees in their habitats and is difficult to control. Horticulturist and organic farmer Nathan Heinrich attributes its spread to its ability to thrive in different climates and locations.
Identification matters before removal. The tree has compound, fern-like leaves, and the report says its leaflets have small glandular teeth near their bases. Female trees may bear clusters of seeds. Black walnut and some sumacs can look similar, so the report advises confirming the species rather than relying on a quick visual guess.
Foltz says cutting the trunk or damaging the roots can prompt new shoots, known as suckers, from the root system. He describes cutting the tree near its base, drilling holes into the stump and filling them with rock salt as one approach. He warns that salt can make soil unsuitable for new plantings. Heinrich suggests stump herbicide as an alternative and says repeated cutting may eventually exhaust the tree’s energy reserves. These are expert recommendations reported by House Beautiful, not a guarantee of eradication.
Risks Beyond the Tree Itself
The tree can affect more than the patch of ground where it grows. According to the report, its roots may spread far from the trunk and can damage hardscaping or pipes while seeking water. The tree can also compete with nearby plants, making an established specimen a concern for homeowners and local landscapes.
The report also says tree of heaven is a host plant for spotted lanternfly, citing the U.S. Department of Agriculture. That connection does not mean every tree will be infested or that removing a single tree will control lanternflies. It does make accurate identification and informed management relevant beyond an individual yard.
Removal choices can carry trade-offs. Rock salt may harm the soil where it is used, while cutting alone may encourage resprouting. Homeowners need to weigh control against effects on surrounding vegetation and planned planting, and may want advice from a qualified local arborist or invasive-plant specialist.

How Tree of Heaven Spreads
The source report says tree of heaven can produce large numbers of seeds and establish in places such as sidewalk cracks and gutters. It also describes the tree as capable of rapid growth, citing Heinrich’s account that it can grow as much as 15 feet in its first year. That figure is presented in the report as a possible growth rate, not a forecast for every tree or location.
The experts’ warning centers on the tree’s response to damage: new shoots can emerge from roots after the trunk is cut or the root system disturbed. Foltz calls the plant difficult to control, while Heinrich points to its resilience and capacity to resprout. The source does not provide a location-specific removal protocol, independent trial results, or a comparison of success rates for the methods discussed.
“The tree “will respond by sending up suckers from the roots that will grow into new full-size trees” if its root system is damaged or the trunk is cut.”
— Logan Foltz, certified arborist at Urban Arborists, as quoted by House Beautiful
Choosing a Method for Each Site
The report does not state how effective or fast each removal approach is, nor does it compare outcomes across different soils, tree sizes or root systems. It also does not establish that rock salt, stump herbicide or repeated cutting will work in every case. The timing recommendation to treat stumps in July and August is attributed to the experts, but the report does not specify how broadly that seasonal advice applies across climates.
It remains a site-specific decision whether to remove a mature tree or leave it in place. Foltz recommends considering its ecological impact and whether native planting would better serve the area. The report does not provide local regulations, disposal guidance, or a diagnosis for any particular tree or property.
Confirm the Tree Before Acting
Homeowners who suspect they have tree of heaven should first confirm the identification, especially because other trees can look similar. They can then ask a local arborist, extension service or invasive-species authority which control options fit their site and local guidance. Any stump treatment should account for possible effects on soil and nearby plants, and herbicide use should follow its label and applicable rules.
For trees near pipes, buildings or other structures, an on-site assessment can help establish the extent of the roots and the safest course. The source report does not announce a new government action or a fixed follow-up date; the next step for an individual property is a species check and a removal plan suited to its conditions.
Key Questions
Why shouldn’t I simply cut down tree of heaven?
According to arborist Logan Foltz, cutting the trunk or damaging the roots can cause new shoots to grow from the root system. Cutting alone may not stop the tree from returning.
How can I identify tree of heaven?
The report describes compound, fern-like leaves with small glandular teeth near the base of each leaflet; female trees may have seed clusters. Black walnut and some sumacs can look similar, so confirm the species before taking action.
What removal methods do the experts describe?
Foltz describes drilling holes in a cut stump and filling them with rock salt; Heinrich suggests herbicide applied to drilled holes or slits, and repeated cutting is another method discussed. The report does not establish that any one option works in every setting. Salt can make soil inhospitable to new plants.
Should every tree of heaven on a property be removed?
Not necessarily, according to Foltz. He says the decision for a mature tree should take its ecological impact into account, including whether native planting would better serve the community.
Does tree of heaven attract spotted lanternflies?
The report, citing the U.S. Department of Agriculture, identifies tree of heaven as a host plant for the invasive spotted lanternfly. It does not say that every tree will be infested or that removing one tree will eliminate lanternflies.
