Chinese privet (Ligustrum sinense) is a common invasive plant species in many parts of the world, particularly in the United States. It’s important to be able to identify this plant so that you can take appropriate measures to control its spread. Here are some characteristics that can help you identify Chinese privet:

  1. Leaves: Chinese privet has opposite, simple leaves that are dark green and oval-shaped. The leaves are typically 1-2 inches long and have smooth margins. They may appear glossy.
  2. Flowers: The flowers of Chinese privet are small, tubular, and white. They are typically arranged in clusters at the tips of the branches. These clusters of flowers can be quite conspicuous when the plant is in bloom.
  3. Berries: Chinese privet produces small, round, and black berries that are toxic to humans if ingested. The berries are often present in clusters and are a key feature for identification.
  4. Growth habit: Chinese privet is a deciduous to semi-evergreen shrub or small tree. It can reach heights of 3-16 feet (1-5 meters) or more. The plant often forms dense thickets and can be quite invasive.
  5. Bark: The bark of Chinese privet is grayish and develops furrows as the plant matures.
  6. Habitat: This plant can be found in a variety of habitats, including forests, wetlands, and disturbed areas. It’s known for its ability to outcompete native vegetation and disrupt natural ecosystems.
  7. Invasive behavior: Chinese privet is considered invasive in many regions, including the southeastern United States. Its aggressive growth and prolific seed production make it a threat to native plants and ecosystems.
  8. Time of year: Chinese privet typically blooms in late spring to early summer, producing white flowers that are followed by the formation of berries. This can be a good time to identify the plant.

How to remove Chinese privet Ligustrum

Removing Chinese privet (Ligustrum sinense) can be a challenging task, especially if it has become invasive on your property. Here are some steps and methods to effectively remove Chinese privet:

  1. Assess the Situation: First, assess the extent of the infestation. Determine the size of the area infested with Chinese privet and whether it’s a small patch or a larger stand of the plant.
  2. Safety Precautions: Wear appropriate protective clothing, including gloves and eye protection, when working with Chinese privet. Some people may experience skin irritation from contact with the plant.
  3. Manual Removal:
    • For small infestations, you can manually remove Chinese privet by digging it up using a shovel or garden fork. Make sure to remove as much of the root system as possible.
    • Cut the plant back to the ground, and then dig up the remaining roots. Be thorough, as Chinese privet can resprout from root fragments.
    • Dispose of the removed plants in a manner that prevents them from re-establishing. Do not compost them.
  4. Chemical Control:
    • For larger infestations, or if manual removal is impractical, consider using herbicides that are labeled for controlling Chinese privet.
    • Glyphosate-based herbicides can be effective. Follow the product’s label instructions, especially regarding the concentration to use and the timing of application.
  5. Timing: Herbicide applications are often more effective when applied in the late summer or early fall when the plant is actively transporting nutrients to its roots. This timing helps ensure the herbicide reaches the roots.
  6. Repeat Treatment: Be prepared to make repeat applications if necessary. Chinese privet can be persistent, and regrowth may occur after the initial treatment.
  7. Prevent Regrowth:
    • After removing or treating Chinese privet, consider planting native vegetation in its place to help prevent its return.
    • Regularly monitor the area for any signs of regrowth and promptly address it.
  8. Monitor Surrounding Areas: Chinese privet can produce berries that birds may spread to surrounding areas. Keep an eye on neighboring areas for new infestations and address them promptly.
  9. Consult with Experts: If you are dealing with a particularly severe infestation or need guidance on control methods specific to your region, consider consulting with local agricultural extension offices, environmental agencies, or a professional landscaper with experience in invasive plant management.
