Sudden onset of weeds in lawn
New homeowner here (about a year) and this was my first full season of trying to make the lawn look really nice. Last fall I overseeded with Pennington and in the spring I had to put some more seed down in problem areas and used a starter fertilizer. I have been cutting the grass relatively high once a week, and I have an irrigation system that waters for 17 mins everyday, once a day (first zone is 7 am).
I'm hoping some of you experts can help point me in the right direction. As you can see in my pictures, I'm getting these random weeds all over the yard. I've done some research, and have a feeling it may have to do with my watering routine? I was considering using a weed-n-feed but read some negative comments on those. You'll see another part of my back yard (where the dog eliminates) that I'm not as concerned about, but I have a feeling the weeds are germinating from that part of the yard because I haven't spent any time weeding the corner.
Let me know your thoughts..
