Trumpet vine here is a seriously invasive plant, spreading by thick runners, coming up through cracks in the concrete, spaces between pavers, against a home's foundation (can you say foundation cracks and seepage?) and throughout the garden and lawn, not to mention your neighbors' yards even a few houses away. They're pretty, but I would never plant one, or any other invasive vine. I urge readers to research any vines they're considering for covering chain link fences or for any other landscape purpose.
The lovely ivy-covered west side of a previous home (planted by a previous owner,) cost thousands of dollars in tuckpointing and foundation repairs, damaging the mortar between the bricks and cracking the foundation in several places.
A current neighbor's ivy climbs and chokes our arborvitae and is a constant maintenance headache for us, invading our foundation plantings, and our shrubs and path on that side of the house. If you don't care about what invasive vines can do to your own property, please consider the neighbors. They'll thank (or curse) you for your care of lack of it.
One way to help 'contain' these invasive trumpet vines...Plant your starter vine or seeds in a large plastic container (like the ones you get plants in from the nursery). When ready to plant along your fence, trellis or other surface...cut the BOTTOM from the container, and plant container and all, leaving about 2-3 inches of container above ground. This will prevent root spread to a point, then all you have to worry about is where the seed (pods) drops.
I don't know of any way to really prevent English Ivy and other invasives except mow or cut away from areas where they are undesirable.
