I live in Massachusetts and this season I have been getting a significant amount of L shaped burn marks in my lawn roughly 1ft x 1ft. I just can't figure it out. It makes no sense. I don't own a dog. I am suspecting deer. I don't think it is my fertilizer because it pops up randomly. Over the course of this season I have had this happen about 15 times. I had it happen a few times last year. I'm so confused as to why they are L shaped marks.
I've put out a trail camera but haven't gotten anything on camera except for me mowing the lawn.
Any thoughts??? I find nothing on the internet about this except for dog urine issues.
Thank you
