For pre-emergent control of Annual Bluegrass you will normally treat 2-3 times to fully control it throughout the year. For Southern zones like NC, you would do a fall application by Oct 1st and for spring you would do a second application between February and March 15th at the latest. Dimension will only control Annual Bluegrass as a pre-emergent so you will need to make sure the area is free of the currently growing vegetation. Please let us know if you have any other questions.
