1. Why doesn't bauhinia blossom?

1. Lack of nutrition: Bauhinia does not bloom, which may be due to lack of nutrition. Flowering naturally needs more nutrients than usual, and not flowering is probably caused by long-term fertilization. Fertilize frequently during the growth period to ensure vigorous growth. Top dressing is needed to promote flowering before flowering. 2. Improper pruning: The failure of Bauhinia to blossom is probably caused by improper pruning. Generally, two to four-year-old branches are easy to bloom. If there are too many old branches, it will be difficult for new branches to sprout and grow, and they will not be able to bloom. During the maintenance period, old branches, diseased branches and transverse branches should be cut off in time to promote nutrient concentration and better flowering. 3. Infected with pests and diseases: If the environment provided during the management period is uncomfortable, such as high temperature and poor ventilation, plants are prone to bituminous coal disease. Once the disease occurs, the plant will grow poorly, unable to bloom, and even the whole plant will wither and die. Therefore, we should pay attention to management methods and spray medicine in time.

Second, why does Bauhinia bloom first and then grow leaves?

There are two main reasons for flowering first and then growing leaves. First, its flower buds began in the summer and autumn of the previous year, and when the primordium of each part of the flower was formed, it began to sleep, so that it could bloom in spring. Second, because the temperature required for flower bud growth is lower than that required for leaf bud growth, the demand can be met in early spring, and flowers can bloom. But the temperature can't meet the growth of leaf buds, so it will bloom first and then grow leaves.
