Deb that trumpet vine will put out underground roots and sprout up a long way from the original plant once the original plant is well established. I would say that your plant should sprout new shoots they start leafing out here very late when you are thinking hoping and praying that that nasty trumpet vine is dead. Please take my warning to heart and get rid of it before it weaves it's way all over your garden. I once put my back out trying to dig out a sprout and then pulling on it, those roots are long and deep.
I would at the very least contain it in a very large very heavy plastic container from which it could not escape. Mine was so large that the vines intertwined forming almost a tree like interwoven tree trunk which I pruned back hard and kept the bottom sprouts cut back so it looked like a tree with a trunk about six feet high and it would grow like mad all season constantly needing pruning. Then those sprouts would grow constantly vining on the ground making more roots which needed at least weekly digging, poision and still they would grow. Get rid of the trumpet vine while you can!!!!!!
I purchased a new shovel/spade that is nice and sharp to dig out the last of those sprouts I hope, it cost way more than the TV which was free. By the way don't ever let a TV grow near your house it attaches to painted surfaces with these root like things and will ruin your paint.
