Fertilization: generally, oranges of different length of time need different fertilizer management, usually growing for about one or two years, and can be sprayed with fertilizer on the surface of its leaves. The soil can be applied with low concentration of nitrogen containing fertilizer and added with some phosphorus or potassium fertilizer to assist its growth. And the citrus that has been cured for a long time needs to be added with some urea properly, so as to improve the quantity of results.
2. Pruning: it's better to prune according to the growth of the plant. Generally speaking, if the plant grows a little more vigorous, it needs to be pruned greatly. It's better to advance the time a little. For trees with poor growth conditions, they can be cut less, and the pruning time can be moderately delayed. When pruning, you can repair the interlaced branches or overlapped branches.
