1, lack of light: Although it is like astigmatism, but in the maintenance period can not be long-term light, lack of light when the flower bud can not grow normally, so it will not blossom.It is necessary to give plants appropriate light, especially in spring and autumn, to receive as much light as possible, but remember not to be exposed to strong light.
2. Lack of phosphorus fertilizer: In the process of maintenance, balanced fertilization should be applied. If there is a lack of phosphorus element, it will not blossom.It is necessary to supplement some compound fertilizers with high phosphorus and potassium elements before flowering, which can promote the formation of flower buds and facilitate its flowering.
3, soil hard: plant growth in loose soil environment, root growth is very strong, will also be normal flowering.If the soil becomes hard and airtight, poor root growth will affect its flowering.It should be replaced once a year, and the soil should be turned regularly during the maintenance period in order to provide a loose soil environment for the plant.
