Woolly burdock (Arctium tomentosum)

Woolly burdock

The woolly burdock, also referred to as Downy Burdock, is a tall, biennial plant native to Europe and Asia. Like other burdocks, its flowers turn into large, hooked burrs when they are mature. These can catch on the coats of mammals, which helps the plant spread. Woolly burdock has been introduced in the Americas, where it is considered an invasive species.

Water: Woolly burdock flourishes in diverse climates, especially moist areas. It requires weekly watering to thrive, maintaining a balance between drought tolerance and excessive humidity. As an herbaceous plant, woolly burdock also benefits from rainfall during its growing season.

Fertilize: To nurture woolly burdock, use balanced fertilizers in spring and high-nitrogen options during growth. Fertilize monthly per size, avoiding over-fertilization to ensure flowering. Adjust applications in dormant periods and follow safety guidelines for year-round health and optimal growth.

Pruning: Woolly burdock features coarse woolly leaves and spiny burrs. Prune in early to late spring by removing dead branches and overcrowded stems to improve airflow. Cut back flower stalks to prevent self-seeding. Regular pruning promotes healthy growth and minimizes invasiveness. Sterilize tools to prevent disease.

Propagation: Woolly burdock is a hardy perennial with large leaves and burr-like flowers. Propagate by sowing seeds in well-drained, organic-rich soil, lightly covered for light exposure. Regular watering is crucial until seedlings establish; thereafter, woolly burdock requires minimal care.
