đ¨ Poison Hemlock Alert â Tennessee đ¨
Poison Hemlock (Conium maculatum) is up and about to flower! This toxic, invasive plant is popping up across Tennessee roadsides, fields, and fence lines.
â ď¸ Why itâs dangerous:
Every part of the plant is poisonous to humans and animalsâeven inhaling particles while cutting can be harmful. Itâs especially dangerous to livestock, pets, and wildlife.
đż What to look for:
Tall, hollow stems with distinctive purple spots
Small, white, umbrella-shaped flower clusters
đ Thinking about mowing it down? While mowing may be a solution in some cases, it comes with concerns:
- Tiny plant particles can become airborne and settle in nearby grazing areas.
- Livestock and wildlife may accidentally ingest the toxic debris.
- Mowing wonât kill the root system, and the plant may regrow.
â ď¸ If you choose to mow:
- Wear protective clothing and a mask.
- Avoid mowing on windy days.
- Keep animals and children far away from the area.
𧤠Manual removal tips:
- Wear full protective gear: gloves, long sleeves, pants, and a mask.
- Use a shovel or spade to remove as much of the root as possible.
- Bag all plant material and dispose of it in the trashânever compost or burn it.
- Wash tools, gloves, and clothing thoroughly after handling.
đż Herbicide option:
Targeted herbicide applications can be effectiveâalways read and follow product label directions, and wear the personal protective equipment specified on the label.
đ Removal on private property is the landownerâs responsibility. For additional educational guidance on identification and safe control methods, contact your local Extension office.
