A British researcher said the roots go thirty feet down. If a piece breaks off, it restarts a new plant.
The French call em Liserons, and they have a pail of herbicide and drape them over the pail and let em drink it. I hate them. They climb up my fruit trees.
I hate bindweed too. I use a ton of time managing it rather than focusing on other tasks I should be doing. Roundup hardly seems to faze it. Hand weeding seems to make it pop up in more locations. It’s a constant battle.
that looks like a slightly different species than the hybrid bindweed I’m familiar with.
Bindweed and morning glory!
That seems a bit excessive. The “roots” that bindweed regrows from are actually rhizomes which move below ground, but usually close-ish to the surface. I was able to eradicate them from one area by removing the top 1 foot of soil in the area they were and then kept an eye out for any bits I missed as they regrew. It worked.
Where I live there’s a native bindweed (Calystegia sepium) as well as the invasive one (C. silvatica & the hybrid between the two), but so far I’ve yet to find the native one. I wonder if that means it’s less aggressive… I’d like to try growing it to find out cause I always found bindweed beautiful prior to starting my gardening journey and finding out how hard they are to garden around.
Roundup only kills the parts it touches, which works fine on annuals, but perennials, 2-4d is the way to go. Field bindweed the rizomous one.
I was able to push bindweed back to a property line in another spot with the help of deep woodchip mulch. Not sheet mulching, just mulch. This created a loose layer that the rhizomes preferentially grew through instead of anchoring in the firmer soil below. Each time I pulled a bindweed vine, I was able to also lift long sections of attached rhizome out of the loose mulch. Obviously I couldn’t fully deal with it by the property line, but aside from one small spot where I still find an occasional little sprout, I was able to get the majority of that area bindweed free!
Thanks for putting a name to this plant that is also trying to take over my yard. I was hoping that keeping it mowed low would help control it, but it just keeps it from climbing my trees. Draping it into herbicide is an interesting idea.
I guess what is a nuance to one may be beneficial to someone else. My cattle love field bindweed, it’s like spaghetti dinner to them.
Similarly, it doesn’t seem to survive well where my sheep have access. 
Field bindweed is generally considered a safe and nutritious forage for cattle, containing high levels of protein (12–22%) that can support significant daily weight gain.
Nightmare plant. I’ve pulled the same root up dozens of times from the same spot and it just keeps coming back. My approach now is just stay on top of it around the base of the trees and accept it’ll never fully go away.
