Hello! This is my first post here and I'm glad I found this website! I'm working on a lawn that is invaded by 4 different kinds of weed plants. I am new to all this and don't have much experience... I need help figuring out what kind of weed plants these are and the kind of weed killer(s) needed. Also, I plan on overseeding the lawn (2 weeks after the application) and would like to know if the weed killer(s) will interfere with BlueGrass germination. My location is in North East (Buffalo, NY) and lawn has Fescue/BlueGrass combination. Approx area: 40' x 25'. #1 Click here for Close-Up #2 Click here for Close-Up #3 Click here for Close-Up #4 Thanks a lot!
