I got rid of mine by putting 1/4" thick cardboard over the whole garden, adding 6" of topsoil on top of that, and then being very vigilant to pull any little piece that popped up. Took a couple years, but eventually the huge tuber must have been depleted. I've read that it has a huge tuber many feet underground. You have to keep pulling out the vines so the tuber uses up all it's energy growing shoots, but doesn't get any energy back.

The OP has never come back so we will never know what plant is being called 'Bindweed' here. Calystegia septum doesn't have tubers so your Bindweed and mine must be different plants.

Ours look like miniature pink morning glories. Round up just makes it laugh!

Miniature pink morning glories sound like Convolvulus arvensis, Field Bindweed. But I’m not aware that that species has tubers.

Perhaps they meant a huge rootball? I know you can't dig deep enough to get rid of it.

Even if the field bindweed, sheet mulching or smothering will have minimal effect. This vine has a massive and very deep and wide spreading root system that requires removal or repeated efforts with a strong herbicide to control. Smothering/mulching just causes the vine to pop up elsewhere where the soil is not covered.

And "deep" only begins to describe the situation. Oregon State University estimates the roots can penetrate 20-30 feet into the soil and the seeds can remain viable for 60 years.

gardengal. This has been my experience to date. The only thing I have found to actually kill the stuff is herbicide, but I would like to find an alternative. To clarify some posts. The bindweed I"m referring to is a small dark green leafed vining plant that has white blossoms and very deep tubers. I have dug them up and eliminated them as far down as a foot and a half to only have them reappear in one or two years. When initially setting up the garden I soaked the ground and covered it with 6 mil black plastic that fried the ground for three months. When I removed the plastic there were still root type vines in spots!!

Well, I do the same thing lgtung did and it's gradually improving. I'm doing the yard bit by bit, which makes it a lot harder to get a grip on, but I can say we have less now that we did. We have the ones that look like big white morning glories, though I've seen claims that it's not convolvulus. I've given up trying to decide which bindweed it is and just try to kill it - along with cleavers, the Himalayan blackberry and the buttercup. I pretty much just ignore the herb Robert and the dead nettle because who has the energy?

I've been dealing with bindweed in my Colorado gardens for years. It seems every house we've moved into contained bindweed. My favorite method is to carefully gather the vines and stuff them into a small, dark plastic pet waste bag. Spray Roundup into the bag, seal it and place a rock on it so plastic bags aren't blowing around the neighborhood. The bag keeps the weed killer away from other plants and provides intense heat from our Colorado summer. I leave them disguised and gather them up and throw away when I do my end of the summer clean up. I had bindweed growing through low junipers and this worked great, although you must be diligent if it rears up in another location. I hope my reply is not too late. Sorry if it's not organic but bindweed is a fierce weed.

Once again, as stated already by floral, it would really help if anyone commenting knows the species of bindweed they are referring to. It could be Calystegia septum, Convolvulus arvensis or a Fallopia species.

All I can say is why why why didn't I listen to floral two years ago when she told me to get rid of every bit of root before it spread further.... and likewise with equisetum. I have both mixed with ivy and mint..

If you were to let those 4 battle it out. who do you think would win? I've gotten rid of the Convolvulus bindweed in the front lawn and back garden by continuously removing any green growth. The only agressive plant I'm dealing with now is a trumpet vine, Campsis radicals. The way I see it is if you see any bindweed anywhere just pull it out till you can't see anymore.
