Nitrogen fertilizer was applied before buds appeared, and then phosphorus and potassium fertilizer were the main ones.
4. Lighting: Plenty of sunshine is conducive to its better growth, but it should be shaded in a proper amount when it is hot in summer, and the spring, autumn and winter festivals can be placed directly in the sun; When the light is not enough, it will affect its flowering. When flowering, avoid being exposed to strong light.
