I am purchasing the following vines:
Clytostoma callistegioides (violet trumpet vine)
Campis grandiflora (chinese trumpet vine)
I am doing to get them growing across the rafters of my greenhouse. I do realize that I will need to constantly trim them up so that I don't have monster vines that take down my greenhouse.
My question is, what size pots should I place them in and is there a good soil mix for them? I really want to have some large, luscious vines growing up and across my greenhouse. I picked these as I think the trumpet vine and wisteria will get large and really spread out well and I am hoping they provide some beautiful fragrance in my gh. I also picked them for hummingbirds and I always hatch praying mantis in my greenhouse and they love large vines to hang out in.
Any help to get these vines off to a really good start would be greatly appreciated.
