You can easily control black medic by keeping a routine mowing schedule. But if your lawn has this noxious weed, this is an indicator of compacted soil. Aside from hand weeding to remove the black medic, you can reduce your compacted soil by helping it breath with aeration then work in overseeding to fill up bare or thin patches of grass.
