Worse than weeds. You can get rid of most of them with Preen. Nothing gets rid of VC. You try to find the roots and pull them up, an impossibility in many spots. We've fought a 25 year battle with them; they're always winning.
Virginia Creeper is winning the battle with my Canary Island Date Palm. It is rooted up in the base of the old fronds, along with the climbing ferns. I have to pull it out twice a year, or the palm would become a Virginia Creeper tree.
Virginia Creeper thrives here in NH, too, unfortunately. I spent the better part of a month this summer pulling it out of the ground and off trees it was choking out. I can't imagine wanting it or planting it unless you wanted to disguise a fence as a woody plant. And then only if the fence were alone in an otherwise empty field.
Well, I guess I am on the opposite side of the fence. I LOVE Virginia Creeper. It used to cover the screened in porch of my great grandmother's house in NEVADA...yes, it grew beautifully in the desert where few other things would grow. I have also used it on fences in the foothills of the Sierra Nevadas. Now we live in Colorado in USDA Zone 5 and I have found VC grows and winters over here too. I have used it to shade a west facing front porch and on a fence in another house and now have it growing alongside of a small fiberglass waterfall in my front shade garden on the north side of our home and I have 2 started that I hope will eventually shade the south face of our home and make our family room a little cooler in the summer. So far, it sure hasn't become too invasive for me! We also recently put in a storage shed and I will probably put some on the hot south facing side of it.
Oh, gawd, don't get me started on Virginia Creeper! When we first moved from NYC to Savannah we rented a lovely house with a garden that had been neglected. Virginia Creeper everywhere... I fought that stuff for days on end, pulling it out of camellias and azaleas, out of a huge pecan tree, and off the house and porch. I wound up pulling up underground runners as thick as my wrist. Then I found where it had headed under the house... I pulled and pulled and pulled and pulled and probably yanked out 150 feet of vine, all pale and creepy looking from where it had been prowling around under there looking for a place to go. It may be fine in a climate where it freezes solid during the winter, but down here it's worse than ivy.
It does freeze here in the winter and goes completely dormant and leafless, so it's not hard to see if it's gone astray and is easy to cut then as the new growth comes out on the old wood. But thanks for the warning anyway!
