What do i need to do to get my wisteria to blume?
I live in New England, not exactly Wisteria country but years ago I planted two next to a pergola, and they are over taking the house. I got no blooms for many years and after putting in a patio next to them the following year one bloomed. The other still has not. I asked my nursery guru about it and he said that if you injure the plant by cutting down into the ground (cutting the roots) it will produce flowers. He said it feels threatened that it is going to die and sends out flowers (they produce the seeds) to carry on the plants future generations.
Reply:Hey, one of my professors at SUNY Cobleskill recommended stressing wisteria by cutting the roots with a spade. Go around the base of the plant with a sharp spade or shovel. You can also give your wisteria a fertilizer heavy in Phosphorus to encourage blooms.

Wisteria can take 7-10 years before it will start blooming.
Reply:You may be able to graft an older, well established wisteria to your extisting one and that may help to get it to bloom.
