This is the 2nd season for my wisteria vines (I have 2 growing over a large arbor). I'm just now learning that I should be pruning in Jul/Aug to about 6 buds. Is it too late for that? It is now September 25? Thank you.

You can inhibit blossoming by pruning incorrectly but if the plant is healthy for doing so , no harm.
Here is a refresher article for you.
