Understanding the life cycle of black medic is fundamental for successful management. As an annual or perennial weed, it reproduces through seeds. The seeds, resembling tiny black capsules, are dispersed by various means, contributing to the widespread presence of black medic.

  2. Mowing Practices: Regular mowing can help control black medic by preventing the formation of flowers and reducing seed production. Adjust the mower height to discourage weed growth while promoting the health of the surrounding grass.

  3. Chemical Control: Selective herbicides designed for broadleaf weed control in lawns can be applied to target black medic. Follow product instructions carefully and apply during the weed's active growth phase.
