Interesting that thistles are rhizome! I didn't know that! They are a pain though, indeed. Hopefully, since this is the first one ever in this area of our property, perhaps it was from a seed. I didn't see any roots running outward from it. Fingers crossed anyway!

Because we live in berry country, we also have to fight the rogue blackberry vines as well. Not so much in the garden area, but in the forest in small open spaces. If left to their own devices, they can literally devour anything in their path. We've got a cap for our pickup truck, and although I know where it is, you cannot see it anymore! Craziness!

Hopefully, both you and I can at least keep the garden areas under control! Take care and happy gardening @jayna!
