Hi My mum bought a Wisteria Frutescens a few weeks ago (maybe longer) with the hope of getting it to grow up get fence. She is a complete garden novice (as am I) and didn’t really know what to do. Since then she had become VERY ill and it’s been left in its pot. I really want to sort it for her to cheer her up but like I said, I am a complete novice. The problem is, it’s in quite a big pot and so when placed on the wall against the fence she wished it to grow on, it’s no where near the fence so can’t see how it would reach haha! There is a small gap between the fence and the wall (possibly a hand width) so wondered if something like a planter bag would fit down the gap and then I plant it in there? Not sure if that would be good enough for the plant to grow :( Also, the plant is established and it already around some trellace so not sure how to deal with that? Any advice would be great, I’ve included a picture of the plant as it is currently. It’s is in front of the wall/fence she wanted it to grow up.
