Botanical Name: Wisteria floribunda
Wisteria is an elegant and colourful woody climbing deciduous specimen with alternate dark-green pinnate-like leaves. It produces clusters of flowers in white, pink, purple, or violet depending on its cultivar. The Wisteria floribunda, also known as Japanese Wisteria, and the Wisteria sinensis (Chinese Wisteria) are both very popular with bonsai enthusiasts.
Because the main feature of this tree is the cascading, clustered flowers, any style that accentuates this characteristic, such as informal upright, slanting, semi-cascade, and cascade, will most likely the best display choice.
Location and Position
A full, hardy tree such as Wisteria should be kept outdoors all year round in full sun exposition. But because we will move it to a pot and not on the ground, a little protection during winter, such as being placed under a bench, could be a safe choice.
This is a very thirsty plant that requires a great amount of watering from spring to summer. In autumn and winter, you can go back to the rule of keeping the soil moist but not soaking wet.
This plant has very strong growing habits which require some support in terms of feeding. It is also important to know that Wisteria can produce nitrogen on its own. To allow it to flower regularly, use fertiliser without nitrogen or a very small quantity only.
Pruning and Pinching
Maintenance pinching is best carried out after the tree has flowered while structural pruning is easier during autumn. Pay attention not to remove flower buds.
Repotting and Soil
Repot in early spring every other year in a well-drained soil mix, such as two parts akadama and one part pumice
Wiring is best carried out when the Wisteria loses its leaves in autumn
