I replanted annual rye a few weeks ago and it is growing in 85% of the yard. The 15% where there is 0 growth is covered in dead brown spots which I thought was just the fescue going dormant. The brown grass was so thick and hard I could barely even rake it up....I tilled most of it down to the dirt....and reseeded....
Does this sound like it was crabgrass that I pulled up? Is there something else I need to do? HALTS?
