What is this plant/weed? It's ruining my garden
Hello, I have a plant that grows in my vegetable garden that comes up from hearty roots under the soil. I cannot find an ID from weed galleries. It grows upright until it is too tall to hold itself up. This is a photo of tall one that has already bent over and is laying on the soil. It seems to have a system of roots under the soil. Almost like a tree would. Sometimes I cannot even break it off and have to cut it back. The leaves are smallish. I'd say around an inch.
Also, how do I get rid of this thing?
Thanks so much.
