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. A good step to take this winter would be cutting down all the trees, and removing as many of the popcorn-like seed clusters as possible. Stump regrowth can be treated with a herbicide in the spring.
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.
