1, reasonable fertilization kumquat loves fertilizer, but is also afraid of hypertrophy. If there is a lack of fertilizer, it is easy to drop fruit after flowering. However, if too much fertilizer is applied, it is easy to sit still after fertilizer loss. Also, when kumquat is fertilized, too much nitrogen fertilizer is applied before flowering, and it is easy for flowers to wither ahead of time and it is not easy to set fruit.
Fertilization management: To fertilize kumquat, nitrogen, phosphorus and potassium can be used, which can promote flower bud differentiation and branch growth. When flowering and fruiting, phosphate fertilizer is needed. We can add calcium superphosphate to nitrogen fertilizer, which can promote fruit setting. Generally, dilute liquid fertilizer can be applied once every 8~ 10 day.
Kumquat likes slightly acidic soil. If often watered with alkaline water, kumquat is also easy to drop flowers and fruits. So we can apply 0.2% ferrous sulfate water-soluble fertilizer to kumquat every 30 days or mix it with liquid fertilizer.
2, proper watering kumquat likes a humid environment, but also afraid of water accumulation. Once there is stagnant water, kumquat is prone to root rot and easy to drop flowers and fruits. But the soil is too dry, and kumquat is easy to fall leaves and fruits. Then how to properly water it?
Water suggestion: We water kumquat. In spring and autumn, you can wait for the soil to dry before watering it again. When it is hot every day in summer, in addition to watering kumquat in the morning or evening, you should always spray water around the flowerpot to keep the air moist.
Kumquat is in a semi-dormant state in winter, which requires less water and evaporation, so watering is less. If you water kumquat, you can water it at high temperature at noon to prevent root rot caused by low temperature at night.
3, plenty of sunshine Kumquat likes plenty of sunshine, if the sunshine is insufficient, it is easy to bloom less, bear less fruit, and even not easy to bear fruit, so be sure to pay attention.
We can raise kumquat in spring, autumn and winter when the sun is shining. When the temperature exceeds 37 degrees in summer, it needs to be kept in a scattered light environment. Because the temperature exceeds 37 degrees, kumquat is easy to sleep. In this case, it is not conducive to kumquat fruit setting.
4. Warm environment Kumquat likes warm environment. The suitable temperature for growing period is 23~29 degrees. When the temperature is higher than 37℃ or lower than 10℃, it is unfavorable to the growth of kumquat, and it is easy to shed leaves or fruit.
Temperature suggestion: when kumquat is raised in winter, it can be kept indoors at 15 degrees or above. The temperature is too low, which is not conducive to the growth of kumquat, and there will be fruit drop. Be sure to keep warm.
When it is hot in summer, we can keep kumquat in scattered light, and it is in a well-ventilated environment. When the weather is dry, we should often spray water around the flowerpot. This can not only reduce the temperature, but also reduce the occurrence of pests and diseases, because once pests and diseases appear, kumquat will also drop fruit.
The fruit drop of kumquat after flowering is mainly related to improper fertilization, too little watering, insufficient sunshine and low temperature. As long as the above four points are achieved, Red Jin Ju can be covered with branches again, which has a beautiful meaning and makes people feel particularly comfortable at home.
