Hello, 1- 13-year-old citrus should be applied with quick-acting fertilizer half a month before each new shoot germinates and during the period when the new shoot stops growing. It is suggested that the granular water-soluble fertilizer of Haicanwo should be used as topdressing, and it should be applied 1 time every month during the growing season from April to September, about 5 times a year.

Fruity citrus:

That is to say, citrus planted for more than 3 years (the first fruit) is mainly applied with germination accelerating fertilizer, fruit strengthening fertilizer and sun returning fertilizer.

1. Fertilization for accelerating germination starts from March to May, and is usually carried out before the spring shoots germinate.

Fertilizers for fruiting fruits are usually applied from the end of May to the middle of June. This stage is the cell division period of young fruit, which requires a lot of nitrogen, phosphorus and potassium fertilizer. Therefore, we should pay attention to fertilization, properly supplement potassium and calcium fertilizers, and reduce physiological fruit dropping and cracking. It is suggested that calcium fertilizer should be used in seafood, which will not antagonize other elements and reduce fruit cracking, with obvious effect.

3. Returning fertilizer to the field is to fertilize the citrus after harvest, mainly applying bio-organic fertilizer.

Of course, in addition to the above fertilization, there are pre-flowering fertilizer, flower withering fertilizer and so on. For citrus fruit trees with lighter leaves and more flowers, quick-acting nitrogen fertilizer can be applied once more, and vice versa.
