1, the flowerpot should be bigger, so as to prepare for potting citrus reticulata to fertilize and loosen the soil in the future.

2. Add sandy loam or sandy soil rich in humus, some organic fertilizers, etc. In potted soil, to ensure certain nutrients needed for the later growth of citrus trees.

3. Orange trees are sunshine-loving plants. Be sure to put potted orange trees in sunny places. Sunbathing can better promote the growth of orange trees.

4. Pruning is very important. Pruning the messy branches of orange trees is not only beautiful, but also ensures that other miscellaneous branches absorb excess nutrients.

5, watering is very important, we must grasp the degree and adjust according to the soil. Generally, water should be watered once a day in summer, and then it should be adjusted according to the soil.

6. The orange tree is a kind of fruit tree that is not hardy. It is best to move potted orange trees indoors in winter.

After the orange tree blooms, it must be fertilized once a week, and the flowers and fruits should be properly thinned, and some buds should be thinned before flowering.

After the flowers withered and set fruit, some young fruits in the wrong position were thinned out. The purpose of this is to prepare for the later flowering and fruiting of citrus reticulata. Fertilization must be prohibited after the fruit is ripe, otherwise it will lead to premature ripening and premature falling of the fruit.
