Oh, great! Now there’s two of you thinking it’s pot!!! No, looked up pics of ditchweed and this isn’t it. Mine doesn’t have stalks of leaves on top of leaves like the pics show. I haven’t heard of any stupid neighbor growing pot. Still, the whole bed is getting dug up first thing tomorrow.
Lawdy, I’m never going to get to sleep tonight!
I once got a packet of seeds for Swiss Chard (green, not the red stuff) and those seeds are VERY obvious for what they are. If you ever see one, you would never miss the ID. And in the packet were two little round seeds that DIDN'T look like they came from the planet Klingon. I assumed they were okra and dumped them at the gutter, because I didn't want them in my chard.
Buy certified seed.
Or better yet, save seed.
