I have a well-established Bermuda front yard. My back yard, however, has a lot of shade and the Bermuda sod did not take very well. This past fall, I seeded the back yard with Kentucky Bluegrass in hopes of having a better looking back yard. This has led to a potential problem, the KY bluegrass made it to the front yard somehow (wind, feet??)! I have been told the KY bluegrass will choke out my Bermuda. Is this true and is there anything I can do about it? Right now, so I'm hoping there's a solution!
