I'm thinking one of these, buy may be totally off - fleabane or smartweed. I can't do 'apps'. Thanks.
This is the most common fleabane and has serrated edges.
This is smartweed. So I am guessing neither.
How certain are you of this? I had smartweed in my first list. I have a buffalo grass lawn and need to adjust my weed spray mixture to include this. But have no idea what it is. Did you use an app?
No I just know common weeds and plants. I am certain of the pictures.
Ask your county or state Extension service.
what state are you located in?
The Extension service was clueless. I suspected this would happen, which is the reason I brought it here for many, many eyes. Oh, well. I'll pull it by hand...
