Can you signal with a circle which is sowthistle?I only recognize some things in picture three. There are some smaller plants in there that are sow thistles (one of them has a seed head that looks like a dandelion). The big one is horsetail. Not dangerous but not edible and turns into a hideous, large weed. I’d pull that one; it might give the thistles room to grow. Thistles are good.
