Perennial Ryegrass Getting In My Kentucky Bluegrass
So I have what I think is Perennial Ryegrass popping up all over my Kentucky Bluegrass lawn. I noticed it late last fall. I would see these greenish-blue colored grasses growing in where some of my KBG had died due to some grubs. Earlier this spring I realized they weren't KGB and started pulling them up wherever I noticed them. Now I'm seeing them even in the thickest areas of KBG (my lawn does well and is thriving at this point).
My question is, should I really care that it's getting into my lawn? Could they have been there all along? The lawn is only 3 years old. Aesthetically you can barely tell a difference between the two grasses but will the Ryegrass outcompete the KGB? Any ideas or advice is appreciated.
