What is Burr Medic?

Burr medic (Medicago polymorpha), also known as burr weed, is a type of trifoliate weed that can quickly spread throughout the lawn and garden if not controlled.

You can recognize this weed by its green serrated leaves and reddish purple colored stems that creep closely along the ground. It also has small yellow flowers. After flowering, the tiny green pods produce prickly burrs. These will eventually dry up and turn brown, spreading seeds everywhere.

Once burr medic has been eradicated, you’ll want to improve the health of your soil to minimize its return by amending it with organic matter or compost.

Appearance: This common lawn weed has a strong taproot; leaves are deeply notched. Yellow flowers mature to puffballs. Dandelion seeds are like parachutes that fly away in the wind—they’re the plants that you would blow on and “make a wish” when you were younger.
