To remove hogweed from a garden, wear protective gear and use a spade to cut the roots of the plant. Use insecticide when manually destroying the plants doesn't effectively control new growth. The process of removing hogweed can take several weeks.
- Wear protective gear
Wear goggles, a long-sleeve waterproof jacket, waterproof pants, gloves and leather boots to protect the skin from irritation when removing hogweed.
- Cut the plants below ground level
Use a spade or shovel to remove the plant by cutting the roots at least 6 inches below ground level. Removal with a spade is most effective when the hogweed growth is minimal.
- Dispose of the plant
Use the spade to place the hogweed into a thick garbage bag. Move the plant carefully to ensure any seeds on the plant are not distributed into nearby soil.
- Check for new growth regularly
Remove hogweed while the plant is very small to minimize the risk of skin irritation and ensure the plant does not have time to develop seeds. Monitor the affected areas weekly, and remove new hogweed plants as needed. Herbicide can be applied to areas where hogweed is difficult to control or if the hogweed has produced and deposited seeds.
