Wisteria can be sown, divided, pressed, cuttings (including root plug), grafting and other methods of reproduction, but the harvest fast, the number of good quality grafting reproduction.
Wisteria can be grafted not only with wisteria, but also with acacia trees, after grafting not only grow faster and more beautiful.
Sowing propagation
Sowing propagation is carried out in March. seeds are harvested in November, remove the skin of the pods, dried and stored in bags. Before sowing with hot water to soak the seeds, when the temperature of boiling water down to about 30 ℃, fish out the seeds and wash in cold water for a few moments, and then moisturize the pile of a day and night can be sown. Or store the seeds in wet sand and soak them in water for 1 to 2 days before sowing.
Pressing, dividing, grafting are carried out in mid- and late March.
Cultivation and transplantation
More than in the early spring planting, planting before the first frame, and the thick branches were tied to the frame, so that it is climbing along the frame, due to the long life of wisteria, thick branches, leafy, the frame material must be solid and durable. When young trees are first planted, the branches can not form flower buds, and only later will bear flower buds. If planted for several years still do not bloom, one is because the tree is too strong, too many branches and leaves, and the second is the tree is weak, it is difficult to accumulate nutrients. The former take part of the cut root and thinning branches and leaves, the latter increase the fertilizer can bloom. Fertilizer should be properly applied more Cuim potassium fertilizer. Fertilizer during the growth period is generally 2~3 times, after flowering, you can leave the central branch 5~6 buds short cut, and cut off the weak branches to promote the formation of flower buds.
Buds appear in March, April full bloom, 20 ~ 80 butterfly flowers per axis. Wisteria prefers sunlight and is slightly shade tolerant. Because wisteria is a large vine, in order to make it fertile, usually set up a certain trellis for cultivation. Wisteria also has shorter species and varieties can be used as potted plants or make bonsai.
