Some gardening enthusiasts have planted wisteria, but it has not bloomed for a long time, making them very anxious. Chongqing's Luo Daqiong asks: Why doesn't wisteria flower? The following three answers about why wisteria doesn't flower should be able to clear up the confusion of gardening enthusiasts.
Answer 1: There may be the following reasons why wisteria doesn't flower:
① Poor variety. Under the same growth conditions, some wisterias bloom a lot, some bloom a little, and some don't bloom at all. I once had several wisteria盆景, most of which bloomed a lot of flowers every year, but one was not easy to bloom and sometimes only a few flowers. After three years of grafting, it was replaced with a variety that blooms easily, and now it blooms a lot of flowers every year, fully illustrating the diversity of varieties.
② Problems with cultivation techniques. A. Poor management and malnutrition can result in few flowers; B. Heavy pruning every year leads to a large number of wild branches and is not easy to form flower buds; C. Serious damage to the tree by diseases and pests prevents normal growth, let alone flowering; D. Excessive vegetative growth, the疯狂 growth of wisteria branches, suppresses reproductive growth, and is also not easy to form flower buds.
Countermeasures: A. Choose a variety that blooms a lot. If it is confirmed that it is not due to cultivation techniques, it is necessary to graft in time and replace it with an excellent variety that flowers easily. B. Strengthen management in daily life to ensure the needs of vegetative growth, cultivate an ideal tree shape and vigor; C. Prune reasonably according to the growth momentum, light pruning for strong trees, and the opposite for weak ones; D. For those with excessive vegetative growth, control vegetative growth and promote reproductive growth by applying less nitrogen fertilizer and more phosphorus and potassium fertilizers during the growing season, reducing water, not pruning or light pruning 1-2-year-old seedlings, and other technical means to achieve the goal of blooming more and better flowers.

Answer 2: Reasons why wisteria doesn't flower: ① Seedlings need more than 4 years to bloom. ② Insufficient sunlight for ground-planted seedlings. ③ Too fertile, with too many vegetative branches, not easy to bloom. ④ Improper pruning, reproductive branches are pruned as vegetative branches. ⑤ No potting and changing soil for many years, lack of trace elements. ⑥ Too much root pruning, the plant lacks nutrient accumulation and is difficult to bloom. (Shanghai Ai Jincai)
Answer 3: When young wisteria trees are planted, they cannot form flower buds, but will produce flower buds after another 2-3 years of growth. If the plant still doesn't bloom after several years, there may be the following two situations: One is excessive tree vigor with too many branches and leaves. Especially for solitary wisteria without a support structure, once its branches touch something climbable, it immediately wraps around and expands its "territory," leading to excessive vegetative growth that suppresses reproductive growth, and may not bloom for several years. Measures such as partial root cutting and pruning branches and leaves can be taken to some effect. The other is weak tree vigor, which is difficult to accumulate nutrients, and proper fertilization must be applied. Organic nitrogen fertilizer can be applied before spring germination. Top dressing can be applied 2-3 times during the growing season. After flowering, the middle branches can be cut to 5-6 buds and weak branches removed to promote the formation of the next flower buds. (Shanghai Zheng Yi)
