The vine itself is quite vigorous and will need a strong support to keep up with its fast growth. Wisteria can grow up to 10 feet a year, especially once it's established in the proper environment. Wisteria performs best in deep, moist, but well-drained soil that is neutral to slightly alkaline. Since most gardeners are drawn to this plant for its blossoms, they are quite frustrated by the plant's notorious tendency to produce only vegetation. There are many potential explanations for this annoying problem, including immaturity of the plant, too much nitrogen, insufficient phosphorus, poor-quality plants, and too much shade.
Wisteria needs to reach a degree of maturity before they are able to produce flowers.
In fact, in can take up to 15 years or longer for the blooming stage to arrive. Those who have succeeded in raising wisteria often recommend root pruning, application of super-phosphate, rigorous pruning of the shoots, and planting in full sun. And most importantly, start with good-quality plants that have been propagated from cuttings of plants known to flower while relatively young. If you know someone willing to share a great specimen, take cuttings of the stem tips in July. Avoid planting seedling vines because the genetic variability of seed reproduction makes it impossible to predict their blooming habit.
