Hello,
I have two wisteria vines that are currently climbing up two metal beams (square cross-section, roughly 7cm in diameter, about 3 meters apart). I'd like to the connect the two metal beams with a piece of wire/string so that the vines can connect horizontally (and eventually create a semi-feature).
What would be be the best way to string the two posts together to allow this? I've attached a rough diagram to illustrate.
Thank you
