Hello! I've purchased 4 15-gallon containers of Pandorea Jasminoides - Bowers Vine - that I want to train onto my wooden fence. I want to upgrade the containers which are currently plastic buckets. Would rectangular boxes work? I have a narrow driveway that needs to accommodate my car, so I can't go too wide with my container. How many new containers should I purchase and how many Bower vines should occupy 1 container? I'm looking for quick growth. My fence gets all day sun. Thank you!
