This weed looks like clover but it isn’t related. It was used as a medicinal treatment in ancient times and was the base for tonics and potions. Its leaves are smaller than clover and bigger than oxalis. It sometimes has a purple or darker color and usually grows in the shade.

Control: Black medic is easily killed using Ortho Weed-B-Gon or Bayer Advanced All-in-One Lawn Weed Killer, but you will need to spray several times to get the newly sprouted plants, as the seeds are unaffected by the weed killer. These chemicals will not damage the lawn grasses when used properly.

As with all broad-leaved weeds, spray in between mowing and do not water for several days.
