Wisteria pruning effect

Wisteria grows relatively fast. After two or three years of planting, when the wisteria grows vines and branches that climb up the trellis, it can be pruned and shaped. Shaping includes not only pruning, but also binding and fixing. Shaping not only helps wisteria accumulate nutrients and grow more vigorously, but also allows it to grow into the shape that people want, thereby increasing its ornamental value.

When wisteria is growing, its branches climb quickly and a large number of side branches will grow. The wisteria will become more and more dense, messy and heavy. Pruning, binding and pulling the wisteria branches can make the wisteria breathable, make the density more even, and balance the bearing capacity of the flower rack.

Wisteria pruning time

Wisteria pruning is usually done in spring or after the leaves fall in winter, and is generally done three times a year.

The pruning time for wisteria bonsai is usually before budding in early spring, after flowering and when the leaves fall, and the corresponding seasons are spring, summer and winter.

Wisteria pruning method

1. Summer pruning: Wisteria can be lightly pruned once in July every year, and the dead flowers and old branches should be cut off. Because it can bloom twice, pruning the dead flowers after each flowering can help the plant save nutrients, which is very beneficial for its next flowering.

2. Winter pruning: Wisteria will enter a dormant period in winter, grow slowly or even stop growing. At this time, it can be heavily pruned, leaving only 2-3 buds on each branch and cutting off the rest. In addition, the weak twigs and side branches should also be cut off to concentrate nutrients on the remaining branches to ensure that enough flowers can bloom.

Wisteria pruning precautions

1. Wisteria will grow flower buds in summer. Be careful not to touch them when pruning at this time. They are relatively fragile and will fall off if touched, so be careful when operating.

2. After pruning in winter, wisteria should be placed in a place with a temperature between 5-10℃. It is not tolerant to low temperatures, and a warm environment is more conducive to its dormancy, which is good for its growth and flowering in the next year.
