Additional Info: It is never wise to use a non-selective herbicide such as Roundup on the lawn. Not unless you plan on spraying the whole area off to replant ,or start over with a new lawn. That is why "selective" herbicides were manufactured. They will only kill the targeted weed and not the surrounding grass with possible drift or accidental spraying. Roundup is a no no when spot spraying a lawn!
