(1) Improper water and fertilizer: In the process of flower growth, too much water and fertilizer will cause the branches to grow white, the roots, stems and leaves of flowers will use too much nutrients, and the flowers, fruits or seeds will be undernourished, which will affect the formation of flower buds and lead to no flowers or less flowers. Even if it can bloom, it is easy to drop flowers and buds. Therefore, it is necessary to pay attention to the application of flower fertilizer containing more phosphorus fertilizer or 0.2% potassium dihydrogen phosphate solution during flower bud differentiation, which is beneficial to the formation of flower buds and the pregnancy of buds.

(2) Illumination error: Because different flowers have different habitats, their ecology is also different, some like illumination, and some are suitable for semi-shade; Some like warmth, some like coolness, some like warmth and humidity, and some are drought-tolerant. If their living conditions are not satisfied, it is easy to cause falling flowers and falling buds. Because of this, when we manage potted flowers, we should treat them differently according to the different light required by different flowers.

(3) Soil use: Most potted flowers like slightly acidic and neutral soil, but they are afraid of soil with too high salt content and alkalinity. Even salt-tolerant flowers, when the soil salt content exceeds 0. 1% and the pH value exceeds PH7.5, will also affect their growth and flowering.

(4) Pruning and shaping: If most potted flowers are not pruned and shaped for a long time, the branches will be messy, which will not only affect the appearance, but also consume a lot of nutrition because there are many unnecessary branches, which will affect the formation of flower buds, which is also one of the reasons why flowers will not bloom or bloom less. Therefore, in order to make potted flowers bloom normally, proper pruning is also essential.

(5) Winter care: Most potted flowers are dormant or semi-dormant in winter, and the suitable room temperature is about 5℃. Even if some flowers like warmth, the room temperature should generally not exceed 65438 02℃.

(6) Pests and diseases: Flowers are often vulnerable to pests and diseases in the process of growth and development, destroying their growth and affecting their nutrient accumulation. It is also an important reason for potted flowers falling flowers and buds, so we must strengthen certain preventive measures.
