You can extract a young hemlock by hand or with a shovel.
Be careful this spring: hemlock (Conium maculatum strong>) is a common weed that is toxic to humans and animals. The stems of young plants resemble those of carrots and other plants of the umbellifer family, but all parts of the hemlock are poisonous when ingested, and even dead canes remain toxic for up to three years. Toxins can also be absorbed through the skin and respiratory system.
Hemlock is widely disseminated in King County, and can be found along community gardens and public roads. It also grows along roadsides, in riparian areas, ravines, fields, ditches, and vacant lots. It is favored by damp soil and the sun, but can be adapted to drier soils and shady places.
