Was it a mistake to plant 3 ivy plants in this back corner?

Back in spring I (maybe naively) planted 3 ivy plants in this back corner, because I like the idea of it eventually covering the fences in this corner.

It hasn’t spread much this year, but I am slightly worried as I wasn’t quite aware of how much hatred there seems to be for ivy online. Plus not sure I am legally allowed to do this as neither of these fences are mine.

Should I rip it out before it is too late?
