Pinksand, I think you are correct. Mine don't look much like the pictures at most of the sites, because they are growing in such shade and competing with the Lily of the Valley roots. Hopefully the Boltonia will fill in as I get rid of the LOV. Thanks

Your vine with the orange roots sounds like Celastrus orbiculatus, Oriental Bittersweet. VERY invasive and destructive exotic vine, it has laid waste to some beautiful large native trees in this area. And yes the roots spread far and wide sometimes. Cardboard will work for the immediate area, but if you really want to whack these guys, you need to either persistently pull or mow them, or use an herbicide. A small amount of Glyphosate or Triclopyr concentrate can be applied to the cut stems and will be absorbed by the roots and kill them. Or after they leaf out you can spray Roundup, carefully because you don't want to spray adjacent vegetation (active ingredient in Roundup is Glyphosate). I usually do just pull the smaller vines, was just doing that yesterday as a matter of fact! Ugh.

I planted an ivy hedge over 30 years ago to cover a wire fence. First year it slept, second year it crept, and third year it leapt. This was well before it became a villain and was commonly planted by the highway dept. We have maintained the hedges around our yard all these years. Other plants that have also been planted and removed were English laurel, and buddlia or butterfly bushes, yellow archangel and creeping Jenny. These were impossible to maintain and got ripped out. And every year i weed a few more out of the yard trying to get the last one. But I also have to weed out seedlings of cedar, fir, holly and a wide variety of other trees. Isn't that part of maintaining a yard? Don't even get me started on bindweed. Ivy just needs a yearly tight trim to keep neat. It is still here. Ivy only flowers on wood that is 3 or 4 years old. I've never had any flowers therefore no berries since it is trimmed. Ivy isn't the villain as much as bad/lazy owners. Anyone silly enough to let ivy crawl along a foundation or up a building will have problems, but I wouldn't let even a clematis be up against my home without a trellis. And I've seen a grape vine do the same damage as ivy can do in less time. We have a yard that we turned into a woodland garden due to fir trees and a sequoia tree planted by neighbors along our south property line ten and fifteen years ago. These are pest trees to us. No where in my yard is ivy a ground cover or a pest, but it does provide nesting/shelter areas in the hedges for the Anna's hummingbirds that frequent our yard. We also have a wide variety of birds, towhees, song sparrows, jays, chickadees, juncos, gold finches,and quit a few more because of evergreen fences, bushes and native hazelnuts. Although ivy does change our landscape it doesn't make a desert. Wicki even says deer use it for food. The birds in my yard speak "diversity". I have found the neighbors blackberry patches to be a haven for rats, and possums. The fir trees are also nesting sites for raccoons. The ivy keeps it so that I don't have to look at their unmaintained yards (all four of them). Our dogs have done in the rats, possums and one raccoon that got in the yard. Would I plant ivy again? Probably. But I also have a huge variety of native plants including but not limited to: salal, Oregon grape, trilliums, pacific bleeding hearts, deer and sword ferns, BC ginger. Would I have woodland plants if the neighbors hadn't planted weed fir trees? No, but I am a homeowner and keep my yard up. If grass doesn't grow any more I adapt and have discovered new plants. I have also tried some of the suggested vining plants. None of them did the job I needed them to do. If the people who complain about plants that are changing our wild lands would be out there pulling invasive species on public lands I'd see a whole lot less scotch broom on my commute to work.

oof, looks like there are thousands of them, all very tiny at this point except the few more advanced ones I took photos of. I wonder where they came from... I don't have any Tree of Heaven in my yard or see it in the neighbors yard...
