QuestionDue to health and age we down sized last fall and moved to Beebe. We have a weed that is over taking the lawn. Some call it Johnson Grass. Can mow one day and by the next day it's already big again. Is there anything I can do this fall that will prevent it from coming back next spring?

 AnswerIf it truly is Johnson grass it is a perennial so a pre-emergent herbicide won't work. Since we lost MSMA as a herbicide, weed grasses are tougher to eradicate, but there are a few options for use during the growing season. Quinclorac is now used and is often mixed with 2,4-D as a broadleaf weed and grass killer. It is tough to kill, so good luck.
