Ease of Cultivation 9/10 Suitablity and Ease for Bonsai Styling 5/10
Position Outdoor tree only. Full sun or partial shade.. Wisteria are fully-hardy when grown in the ground but due to the high moisture content of the roots, should be given some protection when temperatures drop below -5°C.
Feeding Feed with a low-nitrogen fertiliser fortnightly after flowering has finished until Autumn.
Watering Wisteria require large quantities of water in comparison to other bonsai species In periods of hot weather during the Summer they will happily tolerate their pots being stood in a shallow tray of water to keep up moisture levels. Water trays, if used, should be allowed to dry out daily.
Repotting Repot every 2 or 3 years after flowering has finished in a basic soil mix to encourage vegetative growth. To encourage flowering, allow to become completely rootbound.
Propagation Basal cuttings from side shoots in early to mid-Summer and root with bottom heat. Ground layer in Autumn or air-layer after flowering.
Pests and Diseases Leafspot, brown scale and aphids might be a problem.
