Black Medic

Other Names: Black Clover, Yellow Trefoil

Type: Broadleaf

Appearance: Black medic is a low-growing, prostrate plant with clover-like leaves. The leaves consist of three leaflets with a distinctive inverted heart shape. The flowers are small, yellow, and clustered at the tips of the stems. While it may resemble clover, black medic can be considered a weed in lawns.

Risk: Black medic can quickly establish itself in yards, competing with desirable grasses. Its ability to fix nitrogen can also impact soil fertility. If left uncontrolled, black medic can lead to an uneven and patchy lawn appearance.

Timing: This weed is most active during the warm seasons of late spring to early fall. It thrives in temperatures between 75°F and 85°F, making these months conducive to its growth.

Outlook: While black medic can be persistent, especially in warm climates, effective control measures can prevent its dominance in lawns.

How to Control Black Medic

Managing this weed effectively requires a combination of preventative measures and quick treatment.

Prevention

Take action before this weed appears on your lawn by following best lawn care practices, especially focusing on the following:

• Maintain Healthy Turf: A healthy and dense property provides less opportunity for black medic to establish itself.
• Proper Fertilization: Regular fertilization helps maintain soil fertility and reduces the nitrogen-fixing advantage of black medic.

Treatment

If you find this weed on your lawn, it’s best to take action immediately. Working with a lawn care professional is most effective, but you can also try these DIY options:

• Selective Herbicides: Apply selective herbicides labeled for broadleaf weed control, targeting black medic while preserving the health of the surrounding grass.
• Hand Removal: In small infested areas, manually removing black medic can be effective. Ensure thorough removal of roots to prevent regrowth.
