I am getting more and more careful about what I pull out when weeding. I leave a lot of the edibles like purslane and lambs quarters and others with beneficial qualities for the garden.
Yesterday I was weeding and mulching one of the garden beds. Found a weed I didn't recognize (if I get a chance later, I'll post a picture). But I noticed all its leaves were covered in holes. Looked a little smaller than typical slug holes, but a little bigger than typical flea beetle holes. But the weed was growing right next to broccoli and cabbage and there were no holes in the broccoli/ cabbage leaves. So I figured whatever it is is doing a great job as trap crop, so I left it alone!
