Hello. Over the past few years, I’ve noticed an increasing presence of an invasive grass. I was told by a lawn care professional that the only way to eliminate this grass is to use something like Roundup or tons of them out. Last Fall, I dug much of it out but see that I missed some or it had already seeded before I did my work. I am looking for advice on how to remove. If it requires Roundup (or something similar), how long do I need to wait to reseed. Attached a re a few pictures for reference. Appreciate any advice you can provide. Thanks much.
