I got a Stuff at the garden center that was like "only kills toxic weeds, leaves grass alone!" and then I got it home and read the full instructions that are "* also clover and violets and a lot of perfectly civilized wildflowers lol"
Some days I think my grandmother's tactic of nuking weeds growing in her brick patios was overkill, then someone reminds me poison ivy exists. Go Guin! I hope you get less itchy later.
