Fertilization of potted kumquat can be carried out properly in spring and after bearing fruit, but it should be noted that fertilization should be avoided in the cold winter. In addition, in different periods to fertilize it, the use of fertilizer will also be different, so we need to master a reasonable fertilization method.
1. Fertilization in spring: after entering the spring, it will grow many new shoots. At this time, you can apply some nitrogen fertilizer to the potted kumquat. The frequency of fertilization is once a week, not too often.
2. Fertilization at flowering and fruiting stage: during the flowering and fruiting period of potted kumquat, some mash dregs should be applied to it. With the continuous growth of the fruit, the concentration of the applied fertilizer can be increased appropriately. At this time, fertilization should not be too frequent. It is better to apply fertilizer once in about ten days.
If the growth is better, the amount of nitrogen fertilizer must be less, otherwise, if the kumquat tree grows more vigorously, the fruit will probably fall.
