what are these weed vines?

last year

i've been battling them for years. if i can't get the roots dug out i try to find & remove all the seed pods. i had one of the first ones at my old house. it had a near 1/4" root that ran horizontally for 30 ft. all 3 can cover surrounding plants completely.

    The last looks like a shoot of trumpet vine, Campsis radicans.

    First one might be honeyvine milkweed. Not sure about the second one, might be a morning glory kind of thing.

    First one is bindweed, a terrible pest. Third is trumpet vine...even worse:(

    I thought the first one was bindweed at first look too. But those bud clusters are wrong for it. Bindweed gets single buds, not clusters like that.

    The 2nd plant is an Ipomoea,(morning glory) species. It could be the weedy and seedy Ipomoea purpurea or another Ipomoea species, like the perennial Ipomoea pandurata. I grow both morning glory species, and I also grow the Honeyvine(Cynanchum laeve) and Trumpet Vine(Campsis radicans). Ive been trying to get rid of my Honeyvine for 4 years. It's extremely agressive and it's difficult to find the suckers, when they are coming up in the midst of many other plants. I just noticed yesterday that 1 Honeyvine sucker was blooming. Any plant will eventually die if it's sickers are pulled as soon as they appear. Treating the cut end of a sucker with herbicide will speed up the process. I have 3 Trumpet Vines. 2 of them are Campsis radicans and one plant is Campsis grandiflora. I have been pulling the suckers on 2 of the plants for decades, and they now only push up a couple small suckers each year, that grow at the location of the mother plant. Again you can treat the cut ends of the suckers that are still in the ground. There may be stronger herbicides that Im not aware of. If you submit a pic of the flower on the Morning Glory, we should be able to ID it.

    A lot of different vines are called bindweed. The name was given specifically to Convolvulus arvense and it's Field Bindweed, Hedge Bindweed is Convolvulus/Calystegia sepius. TWIMC All Calystegia species are Convolvulus again. Any vine that twines itself around other plants can be called bindweed, but it's better to give the given common name(Honeyvine) or the scientific name Cynanchum laeve, for clarity. Honeyvine is so much more than a mere bindweed. Monarch Butterflies use Honeyvine as a host plant. I always check for Monarch eggs or caterpillars before I pull out a Honeyvine sucker. I have the same issue with an out of control Wooly Pipevine, Aristolochia/Isotrema tomentosa, which Pipevine Swallowtails use as a host plant. Honeyvine is in the milkweed subfamily Asclepiadaceae, of the Dogbane family,(Apocynaceae), but unlike most milkweeds, Honeyvine has clear sap, instead of milky latex. Honeyvine might be usefull if.you have a lot of Monarch caterpillars that defoliate your regular milkweeds.
