Red sorrel is a persistent perennial weed that should be eradicated promptly because it spreads throughout the lawn area quickly. The controls that are most effective are made to young plants and plants that are growing new leaves.

Control: Sorrel is controlled 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.

Please use caution when spraying your weeds. Weed killer is a poison, but if handled properly can be completely safe. If you have pets, do not allow them to come into contact with treated areas until the lawn is completely dry. If you have cats, be sure that the cats do not eat grass that has been sprayed.
