Hello Everyone. First time posting here and needing some help. I hope this is the correct section. My mother gets this type of weed in her grass annually. Even when re-sodding major sections (which it seems like she does yearly), it always re-appears. A little more info on her grass: Just outside Chicago in Zone 5 Waters her grass like crazy The area which has this weed (pictures attached) is easily pulled. Doesn't have deep roots. She is anal on how her grass looks so I'd figure someone here might help identifying this weed. Thanks in advance for your help.
