In the process of flower growth, if there is too much water and fertilizer, it is easy to cause white and long branches and leaves, and nutrients are mostly used for roots, stems and leaves of vegetative organs, while flowers, fruits or seeds lack nutrients, which affects the formation of flower buds and leads to no or less flowering. Excessive fertilization and frequent watering during bud pregnancy are easy to cause falling flowers and buds. In the growth period of flowers, if there is a lack of fertilizer and water, the plants will grow poorly, which will easily lead to fewer flowers and poor quality of flowers.

Second, the light and temperature are not suitable.

Because of the different origins of flowers, their ecological habits are also different. Some like light and heat. Some are happy and half yin; Some people like warmth, while others like coolness. If their living conditions are not satisfied, it is easy to cause falling flowers and falling buds, which needs to be understood in advance.

Third, the soil has a high salt content.

Most flowers like slightly acidic and neutral soil and are afraid of saline-alkali soil. Saline-alkali tolerant flowers, such as geranium, rose, etc. When the soil salt content exceeds 0. 1% and the ph value exceeds pH 7.5, it also affects the growth and flowering.

Fourth, no shaping and pruning during the growing period.

Not pruning plastic flowers and trees during the growth period will not only affect the appearance, but also consume a lot of nutrients, affect the formation of flower buds, and lead to no or less flowering.

5. The room temperature is too high in winter.

If the room temperature is too high, it will affect the dormancy of flowers and trees or cause premature germination and leaf pumping, which will consume nutrients. In the second year, the flowers will grow weak, not bloom or be small or withered.

Six, affected by pests and diseases

In the growth period of flowers, they are vulnerable to pests and diseases, which affect the accumulation of nutrients, hinder their growth and cause flowers to fall and buds to fall.

In view of the above reasons, reasonable watering and fertilization, adjusting the growth environment of potted flowers, reasonable pruning and controlling pests and diseases can solve the problems of flowering, falling flowers and falling buds.
