This reminds me of our jasmine bushes that grow on the fence we share with a neighbor. When we moved in 7 years ago they were already established. In doing yard work shortly after moving in I noticed that they had gone up and over the fence then down into neighbors yard. I felt bad about the invasion and trimmed them back to our side. A couple days later I bumped in the neighbor and his wife who expressed sadness that the pretty smelling flowers were gone from their fence. I felt terrible and apologized. They said that it was completely fine with them if the plants grew over, they'd trim what was on their side as it was needed.
The bushes have since grown back and there are plenty of pretty smells for all.
