How Far Can Wisteria Spread Horizontally In A Single Season (year)?

Question

I find lots of upward spread stats but no lateral spread.

Answer 1

It can spread, horizontally, about as much as it can spread, vertically. This is a potential amount, though, as this will be affected by growing conditions.
