The Chinese tallow tree commonly called the Popcorn Tree, due to , Triadica sebifera (formerly Sapium sebiferum) is an invasive plant of significant concern for the southeastern U.S. Historically it has been more prevalent in deep south states such as Louisiana and Florida, but we're seeing more and more of it in eastern North Carolina. If warming trends hold steady, this species could eventually become a massive problem for our region. All Chinese tallow trees are high-priority for removal. Check with your local Extension office for control recommendations.
The images below were provided by a Craven County resident in December, and were taken in an area that had formerly been mowed and maintained. After five years with no mowing, a grove of Chinese tallow trees up to 20-30 feet tall has become established on the site.
When removing the ree start in the winter cutting down all the popcorn trees, and removing as many of the popcorn-like seed clusters as possible. Stump regrowth can be treated with a herbicide in the spring with a stump/brush killer. This tree also sends out root suckers and those should also be treated so grinding up the stump is not a guarantee solution without chemical treatment.
See the Alabama Forestry Commission information note for examples of chemical control options; consider hiring a professional forester or landscaper if multiple trees are involved.
