Hey guys I'm looking for an answer to several complaints I've heard over the years about bent grass. Up here in Mass we get the light green patches in our lawns and customers complain. There's not much you can do other than use a selective spray, round up or prosecutor. Overseed or spot seed and wait till the grass comes up and fills in the nice yellow spot you just made. I need a correct reason to how it spreads and where it comes from. I've asked former bosses and then when I went solo I asked the owner of a fert company that I refer. Not to happy with the answers I got so I come here looking for some incite to how and where it comes from.
