Broadleaf Weed Types – Dog Fennel

(Eupatorium capillifolium)

Dog Fennel, also known as Summer Cedar or Hogweed, is a perennial broadleaf weed. Preferring moist to wet areas, Eupatorium capillifolium does not fare well in thick, established turf and grows best in poorly maintained turf and other waste areas. In the United States, Dog Fennel can be found along the east coast from New Jersey to Florida, and west into Missouri and Texas.

Identifying Dog Fennel -

Dog Fennel can be identified as a short-lived perennial with a thick woody base. Its multiple stems are veritcally growing and multi-branched in the upper flowering portion, while hairy or sometimes smooth below. The color is more reddish-purple toward the base. Dog Fennel leaves are pinnately dissected once or twice into fine linear segments.

Dog Fennel produces daisy-like flowers that, along with its leaves, emit a strong, foul odor when crushed. Dog Fennel has a fibrous root system and reproduces by seeds.

Dog Fennel Control -

Dog Fennel does not typically invade lawns with thick, well maintained and established turf. Cultural weed control practices can be a good preventative measure, including good lawn mowing and watering habits. However, once Dog Fennel is present in your lawn, professionally applied herbicides are best for complete removal.
