How do you get rid of bentgrass in bluegrass?

To effectively get rid of bentgrass in bluegrass, consider using a selective herbicide that targets bentgrass without harming the bluegrass. Applying glyphosate can also be effective, but it will kill all surrounding grass, so it should be used cautiously and selectively. Additionally, improving the overall health of the bluegrass through proper fertilization, mowing, and watering practices can help it outcompete bentgrass. Regular overseeding with bluegrass can also help establish a thicker turf that reduces bentgrass encroachment.
