In addition to selecting shorter species and varieties, pruning and coring should be strengthened to control the plant from being too large. If you are cultivating bonsai, you need to strengthen plastic pruning. If necessary, you can use old piles to plant pots and graft excellent varieties. Wisteria has strong straight roots, so when transplanting, we should dig as many lateral roots as possible and bring the ground. Plant more in early spring. Before planting, you must set up a scaffolding, tie thick branches on the scaffolding and climb along it. Because wisteria has a long life and thick leaves, the scaffold materials must be strong and durable. When young trees are planted, the branches can't form flower buds, and peanut bud will appear later. If it doesn't bloom for several years, it's because the tree is too strong, with too many branches and leaves, and the tree is weak, so it is difficult to accumulate nutrients. The former uses partial root cutting and sparse branches and leaves, while the latter can blossom by adding fertilizer. Fertilizer should be properly applied with more potassium fertilizer. Topdressing is usually 2 ~ 3 times during the growth period. After flowering, 5 ~ 6 buds can be cut off from the middle branches and weak branches to promote the formation of flower buds.

When planting wisteria, you should choose a dry place with deep soil layer, fertile soil and good drainage. If it is too wet, the roots will rot easily. The planting time is generally from defoliation in autumn to germination in spring. The main root of wisteria is thick and long, with few lateral roots, which is not resistant to transplantation. Therefore, when transplanting, no matter whether the plants have soilless balls, they should be replanted, and organic fertilizer should be applied to the planting holes as base fertilizer. They should be watered after planting. For larger plants, a sturdy and durable scaffolding should be built before planting, and thick branches should be tied to the scaffolding after planting to make them climb along the scaffolding. The daily management of wisteria is simple, and appropriate water and fertilizer management can be carried out according to the water and fertilizer status of the soil.

Pruning wisteria is an important work in management, and the pruning time should be in the dormant period. When pruning, the branches are evenly distributed by removing secrets and keeping sparse and manual traction. In order to make flowers flourish, we should also prune them reasonably according to their budding habits. Because wisteria has strong branching ability, flower buds are planted in the axils of annual branches, and the tops of growing branches are easy to dry up. Therefore, we should take back the new branches of that year, cut off 1/3- 1/2, and cut off the delicate branches and the base of dead branches. In order to make potted wisteria blossom brilliantly every year, we need to master several skills besides intensive cultivation with thin tubes.

(1) Pot selection of mature seedlings. Wisteria has straight roots, long main roots and few lateral roots. When transplanting in a pot, take a long taproot and put it in the pot. Cultivate with sandy loam rich in humus, and put a small amount of broken hoof pieces as base fertilizer. The flowerpot should be kept in a ventilated and cool place for a week, and then in a well-lit place.

(2) Flowering in early March, with less watering and fertilization during flowering, to prolong the flowering period. Cut off the residual flowers immediately, so as not to make them pod-bearing, so as to prevent nutrient consumption and affect the quantity and quality of flowering in the coming year.

(3) Cut off the elongated branches and vines in time to prevent them from climbing to the surrounding objects, so as to prevent the loss of nutrition, insufficient nutrition, and inability to bloom or bloom in the coming year.

(4) During daily maintenance, water and fertilizer should be properly controlled to prevent excessive growth of branches and vines, and long-acting phosphorus and potassium fertilizers should be used as the main topdressing.

(5) When overwintering, it should be placed at a low temperature of about 0℃ to keep the pot soil slightly wet and make the plants fully dormant. Next year, the flowers and leaves in spring will flourish and the flowers will be colorful.

Water: Generally, adult seedlings planted in the ground do not need to be watered, only when they are particularly dry. Potted plants are more resistant to dryness when they are watered dry. Wisteria is a vine, which usually climbs on scaffolding or other supports. If the cultivation measures such as tie rod support, vine twisting, pruning and shaping are adopted, the umbrella-shaped wisteria can be cultivated, which is very interesting. In order to keep the shape of wisteria unchanged, efforts must be made in conservation. Because it is a vine with strong climbing ability after all, although it can be cultivated into a tree shape, its properties have not changed, and the vine that is pumped will be entangled as soon as it catches something that will climb. Therefore, in daily maintenance, don't let vines ride on other things, and don't entangle them at will. We must constantly pull out, prune and reshape vines to control their growth, otherwise they will grow nondescript, neither like vines nor trees. Once this form appears, not only will the flowering amount decrease, but even they will not bloom for many years.
