I am still here in California on a residency. We're in a heatwave at the moment - it's far too hot!
I was in the hardware store the other day and noticed these weedkillers. There was a whole shelf full and most of them had dandelion images on the label as an example of which weeds the chemicals can kill.
I have also had two meals here containing dandelion leaves in salads. It seems a bit bonkers there's a whole industry dedicated to killing dandelions when you could just harvest and eat them.
