Folks on this forum tipped me off to a thistle I had in my garden, and I've been treating that at least weekly for the past several months. So I figured I'd turn to y'all for help again.
I've noticed a new weed, mostly distinguished by it's super sharp thorns. I was nearly unable to touch the stems of these weeds even with sheet metal gloves. They are growing tall, and are so solidly in the ground I ended up snipping them near the root because most of them I couldn't pull. Flowers appear to be white in color.
Perhaps it's possible that these are thistle too, but they are VERY different from the other, much more abundant thistle I have in my beds.
It's mid July here in the DC suburbs of Southern Maryland.
