Transplanting
Wisteria should be transplanted before the sprouts in early spring. When planting, it is necessary to take the soil ball and cut off some branches appropriately. For large seedlings of three to four years old, strong pruning should be done on the aboveground branches, generally cutting off the trunk 30cm from the ground, and it can bloom the following year. The plant spacing is 2~3m, which can be adjusted according to the configuration requirements. For planting, two to three-year-old seedlings are often chosen, with a planting hole diameter of 70~80cm and a depth of 50~60cm. Each hole is applied with 1kg of fully decomposed organic fertilizer and 100~600g of bone meal, mixed thoroughly with the soil as a base fertilizer, then covered with a layer of soil before placing the seedlings and filling the soil.
Water and Fertilizer Management
Wisteria has no high demand for fertilizer, and excessive fertilization should be avoided as it can easily cause luxurious growth, thus affecting the formation of flower buds and reducing flowering. However, after flowering, a plant should be fertilized with no more than 75g of phosphorus and potassium fertilizer and 25g of nitrogen fertilizer. If manure or compost is used, it must be fully decomposed and mixed evenly with the soil, applying about 500g per plant. Generally, once every year or every other year before winter, a fully decomposed compost is applied to replenish the nutrients in the soil. After planting, water sufficiently, and then water once every 10 days, continuously for 3~5 times. After each watering, the soil should be loosened to retain moisture, which helps to raise the soil temperature and promote the rapid growth of new roots. Every spring, before and after the sprouts and flowering, a thorough watering is needed, followed by immediate tillage to retain moisture. In the North China region, April to June is the season when Wisteria grows vigorously and blooms, and it is necessary to water thoroughly 2~3 times a month. After July, when the rainy season begins, attention should be paid to drainage to prevent waterlogging. Before mid-November, when winter sets in, sufficient irrigation with frozen water is required.
Pruning
Pruning of Wisteria is generally done before sprouting in spring, mainly removing weak branches, dense branches, withered branches, and diseased branches, and retaining good renewal branches. After the flowers fade, if not for seed-saving, the残花 along with the lower two buds of the inflorescence can be cut off, and some dense inner branches should be thinned, which is conducive to ventilation, light penetration, and a beautiful tree shape, promoting the germination of new branches and the formation of flower buds. After defoliation, diseased and withered branches, thin branches, and overlapping, dense, and徒长 branches should be cut, making the branches evenly distributed, maintaining a round canopy, which is beneficial for the following year's growth and flowering.
Disease and Pest Control
Wisteria diseases include bacterial or fungal diseases, such as wilt and leaf blight, which can be sprayed with Bordeaux mixture 1~2 times before the onset of the disease, and 100g of bleaching powder or sulfur powder can be sprinkled under the shrubs. The main pests of Wisteria are aphids, bagworms, and tussock moths, which can be controlled with a 40% dimethoate emulsion diluted 800~1000 times or a 25% phosphamidon emulsion diluted 1000 times.
