1、 Summer pruning

After the wisteria blooms in summer, it needs to be trimmed. At this time, the dead flowers and dead branches on the plant should be cut off first. Then cut the branches of that year by about 15cm. Because its flowers usually bloom on the last older branches. This pruning can help it bloom better the next year

2、 Winter pruning

It also needs to be trimmed in winter. It is necessary to reduce the length of its relatively long branches by 3-4 buds, that is, about 10cm. In addition, you can also clean up its messy side branches. In this way, the plant can save a lot of nutrients, which is conducive to its winter and its germination again in the next year

3、 Precautions

1. Its service life is relatively long. If disease or insect damage occurs to its main branches in the process of growth, it needs to be trimmed in time, and the branches with good growth should be selected as new main branches in spring

2. In early spring, it will sprout flowers. At this time, some miscellaneous branches without flower buds can be cut off to promote the growth and flowering of branches with flower buds
