Thanks so much for the help man! I had been using a lawn company to do this stuff but what they were doing wasn't really helping to kill weeds with a post-emergence. After doing a good bit of research and y'alls help, I figured I could do it on my own, do a better job, and be more cost-effective. Only problem is that I may not be able to do this pre-emerge until the Spring. The lawn company I used was terrible and so was their communication. They ended up coming out unannounced the other day when I was at work and left a note on the door saying that had sprayed a pre-emerge. I have since cut ties with them and told them not to come back out, but I'm kind of scared to put down the Barricade since they already sprayed a pre-emerge (although I don't have much confidence that theirs will work well). They didn't specify what kind they put down though. Would it be too much strain on the grass to put down my pre-emerge as well you think?
