For homeowners and turf managers who cultivate Kentucky Bluegrass, understanding whether Dimension 2EW will adversely affect their lawns is crucial.
Will Dimension 2EW Damage Kentucky Bluegrass?
Dimension 2EW is formulated to be safe on Kentucky Bluegrass when applied according to the label instructions.

Understanding Dimension 2EW’s Impact on Kentucky Bluegrass
- Selective Weed Control: Dimension 2EW selectively targets weed seedlings, making it an effective solution for maintaining the aesthetic and health of Kentucky Bluegrass lawns without causing damage.

Best Practices for Using Dimension 2EW in Kentucky Bluegrass Lawns
