We have good relations with our neighbours (though they have been funny about us trimming a hedge to lower than about 12ft). A couple of years ago they asked us to replace a fence panel that was falling apart. We did. We have now realised that the ivy growing from their side of the fence is destroying the rest of the fence and we are expecting the demand for us to replace it. We have a roof attached to the fence which covers the log store attached to our garage - this makes it difficult to prune the ivy from our side and it has also grown up over this roof into our garage. Not sure if we can demand that they stop growing ivy up the fence, but we're a bit fed up that it's destroying a fence that we will be expected to replace. Any ideas about what solutions to suggest to them?
