arbor size for hardy kiwi
I have a male and female hardy kiwi (A. arguta) in pots, and plan to plant them in the ground this season. I'm thinking about building a hexagonal arbor with two or three benches underneath. It would be 8 or 10 feet across. Would such a structure be large enough to accommodate both vines? I've read several times how vigorous these vines are, but don't really have a good feel for how much space they take.
The other option is a T-bar trellis along a fence. It's 25 feet long with a 4 foot gate in the middle, so each vine would get about 10 feet of trellis. That site gets a bit less sun and is more protected from wind.
I'm in zone 6 in the Lehigh Valley of Pennsylvania.
