| Re: wisteria which has never flowered? Hi,
As said above, Wisteria can take a number of years before flowering.
Once your plant has covered the required area (and built up enough older wood) you need to prune last seasons wood (the long whippy bits) back to a few buds. The RHS book of pruning if I recall suggests mid-winter. Pretty much like pruning a grape vine then.....hic!
They key is to leave a short bit of last years wood (called a spur) with a couple of buds that should become flowers, if not this year, then in future years.
Rather like old grapevines, this regular pruning eventually develops multi-headed "knuckles" along the permanent branches as you leave a small bit of growth each year, but this is where the flowers will mostly come from over time.
You can also give the current seasons growth a half length prune in late August/September before its final winter prune. This I beleive should also help those basal buds develop into flowers.
