🚨 Poison Hemlock Alert – Tennessee 🚨
Poison Hemlock (Conium maculatum) is up and about to flower! This toxic, invasive plant is popping up across Tennessee roadsides, fields, and fence lines.
☠️ Why it’s dangerous:
Every part of the plant is poisonous to humans and animals—even inhaling particles while cutting can be harmful. It’s especially dangerous to livestock, pets, and wildlife.
🌿 What to look for:
Tall, hollow stems with distinctive purple spots
Small, white, umbrella-shaped flower clusters
🛑 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 won’t kill the root system, and the plant may regrow.
⚠️ 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.
🧤 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 trash—never compost or burn it.
- Wash tools, gloves, and clothing thoroughly after handling.
🌿 Herbicide option:
Targeted herbicide applications can be effective—always read and follow product label directions, and wear the personal protective equipment specified on the label.
📌 Removal on private property is the landowner’s responsibility. For additional educational guidance on identification and safe control methods, contact your local Extension office.
✅ Know what to look for—stay safe this spring!
