Broadleaf Weed – Black Medic

(Medicago lupulina)

Sometimes referred to as Trefoil, Black Clover, None-Such or Hop Medic, Black Medic is a summer annual weed that can also behave as a perennial weed in certain climates and soil conditions. Black Medic is found throughout much of the United States and is typically more active in soils with low nitrogen levels.    

Identifying Black Medic -

Black Medic is an annual weed that features a taproot, that does not creep by rooting at the nodes. Its stems are hairy, growing upright and somewhat square, and its elliptical leaves grow alternate with pinnately trifoliolate ends. Lower leaves on Black Medic plants have longer petioles than the upper leaves. Black Medic weed also features small, yellow flowers that are clustered on the end of the stalk.

Black Medic Weed Control -

Good cultural weed control practices should be sufficient to keep Black Medic weeds at bay, including proper mowing and watering practices. Maintaining proper levels in your lawn’s soil can also help discourage this annual weed.
