If you have a structure that you’d like a vine to climb, you may need to help it along a bit. Some vines adhere to structures and stick to them on their own. But some vines need to be tied or secured somehow. If you don’t have a lattice or something to tie vines unto, you may be able to hang string or wire from the top of the structure for the vines to climb.
I got a beautiful Mandevilla and planted it in the center of an urn. I originally placed the container garden in the middle of a hummingbird garden of red Salvia greggii. The hummingbirds paid no attention to the Mandevilla, so I decided to move the container to another spot and plant a different plant in the hummingbird garden. (I’m experimenting with the hummingbird garden, by the way. Right now, they zoom in for the Salvai greggii and stay to visit other flowers–but never the Mandevilla.)
The new placement for the Mandevilla was in a sunny spot next to a gazebo pole. I envisioned the vine climbing up the pole, but the Mandevilla needs to be tied or otherwise helped along. I couldn’t really bunch up the vines and tie them to the pole–that would be too tight. And I didn’t want to drill screws or do anything else permanent to our structure. So I decided to hang something from the top of the pole.
I intended to get rope but noticed waxed string in the jewelry department of our local arts and crafts store. I placed the string at the top of the gazebo pole and then just “criss-crossed” the string down the poll. You can barely see it (although I think it would look okay if it stood out, too).
I plan to just tuck in the vines under the string as they grow. I may secure them to the string with little pieces of more string if the vines end up pulling the criss-cross pattern too much out of shape though.
You could probably use this same method at the top of a wall, fence, or any other structure that you’d like to train vines to climb.
