Hello everyone! I'm in Boise Idaho where I've lived most of my life. This year I'm in a new house, on property that was very recently (2 years ago) crop land, and all the area around us is also crop land. I have a weed that's going crazy in my garden. I've been pulling it like crazy, but I'm not sure what it is. It isn't one I remember having in my garden before, and it seems more like a crop than the typical Idaho weed. Any ideas? There are actually two different plants here I think, I've got pictures of both. I have pretty much the same amount of both growing. Thanks in advance!
The largest plant in the first picture appears to be a pigweed (Amaranthus sp.)... and some of the smaller plants are likely the same. The toothed-leaf plants, most prominent in the second photo, may be lamb's quarters (Chenopodium album).
