Photos 7842/7843 seem to be an annual grass. Started with a few I pulled out some years ago, a few more each year and now they're everywhere. I try to not mow my grass too often and don't use herbicides. They stick up high tho and I end up pulling them between mowings. Ideas on how to treat? I expect the other is quack grass. Do you agree? I dug some of it out--again not wanting to use herbicides, but expect it to be ongoing problem. ?
