Wisteria cultivated in the open field grows fast and needs pruning. After flowering, if no seeds are left, the residual flowers can be cut off in time.

In the post-flowering period, the over-vigorous branches, over-dense branches and weak branches are cut off, and the short branches at the upper part of the branches are kept to promote the formation of flower buds. And tie the new branches of that year properly to make them evenly distributed on the shelf surface. Pruning should be strengthened if shrub-like or specific tree-like growth is maintained. After flowering, the branches can be pruned vigorously, and before flower bud differentiation in August, the branches can be chopped and thinned. We should control the growth of autumn shoots in autumn.
