Is this poa annua or annula bluegrass?
Hello, Could you folks tell me if this is poa annua or annual bluegrass that is invading my tif 419 (see link at bottom of post)?
If so, what is the best solution? It is thriving and going to seed even though I'm using a reel at .5". It's coming from my neighbor's lawn even though I follow a regular pre/post emergent schedule. I'm afraid his bagless rider is continually shooting it over to my yard. I'm not above a scorched earth policy of a general herbicide but would like to avoid it if possible. Also, I will gladly hand pull all patches if a preemergent would prevent any seeds for germinating. Please educate me.
