: When should I prune my wisteria for the best blooms next year and how far back? I live on Zone 5-6 border. This is an old plant I transplanted this spring and cut back to ground and it has had nice recovery. It is growing up a very sturdy arbor and I want to keep it in control and of course lots of blooms!

"Wisteria can and often needs to be pruned several times during the growing season especially if it is being grown as a tree form. probably the best or most common time is late in the winter just before the plant comes back to life. The main thing to remember is that all the Asiatic spieces flower on the previous years wood, if all this was removed there would be no flowers. Generally it is good to cut back all the new growth to 3 or 4 buds each Spring before bud break. (Once the plant has reached the desired size)".

"As a general rule the Asiatic spieces flower in the Spring on the previous years wood. The cultivars of W. sinensis tend to flower before the leaves emerge, the cultivars of W. floribunda tend to flower after the foliage has started to emerge. The American spieces flower in the early summer on same years wood."
