Wisteria Blue Moon - how to support something so high???
I am in zone 5a and have always wanted a wisteria. I just read that Blue Moon is hardy to zone 4 so I'm thinking of getting the vine to cover a trellis on my deck but then I read online that it can grow up to 25' at it's maturity of 10 years.
How on earth does someone support something so big? I have an arbor but it's only 10' high. Does it no longer need support once it's bigger? Or is it always a vine in need of support? And does anyone have any suggestions?
Also, if I prune it back so it never reaches more than 8 or 10 feet, how many would I need at the base of the fence if the fence runs 12 - 16 feet long? It's lattice that we are using to cover the underside of our 8' high deck.
thanks in advance!
