What is the best fertilizer for orange trees?

Orange tree fertilization time

Generally speaking, orange trees need to be fertilized from late February to early March, mid-to-late May, and November to early December each year, that is, during the plant's budding period, fruiting period, and when harvesting fruit.

What fertilizer to use for orange trees

It is usually more appropriate to apply accelerated nitrogen and phosphorus fertilizers before the spring buds of orange trees sprout. This can strengthen the shoots and improve the quality of flower branches, and can also promote the normal germination of new shoots. If organic fertilizers are heavily applied to the plants, it can help restore the tree vigor and promote the differentiation of flower buds.

In addition, it is better to apply accelerated nitrogen fertilizer after the flowering period of orange trees. It can compensate for the nutrients consumed by flowering, reduce fruit drop and increase the fruit setting rate.

Orange tree fertilization method

Fertilizing orange trees generally uses the method of foliar fertilization, which uses the stomata and cuticle of the leaves to directly infiltrate nutrients. This method of fertilization is quick in effect and has a high absorption and utilization rate. Foliar fertilization can also increase the fruit set rate and promote fruit enlargement and development.

Notes on fertilizing orange trees

Fertilizing orange trees should be done according to the growth of the tree and the conditions of the soil and weather. If it is the dry season, you should water it first to keep the soil moist, and then apply fertilizer to facilitate root absorption.

In addition, for vigorous orange trees, it is important to be careful not to apply too much nitrogen fertilizer, otherwise it will cause fruit drop even when the shoots grow excessively in spring and summer.
