How Many Times a Year Does a Mango Tree Bear Fruit? Grow It This Way for a Bigger Harvest

Mango, also known as mamuang, is a fairly common fruit in our country, and because it is rich in nutritional value it is called the tropical king of fruits; eating it regularly can replenish the various elements the human body needs. So how many times a year does a mango tree bear fruit? How should you grow it to get more fruit?

Generally it bears fruit once a year. Mango trees have the habit of flowering in all four seasons. As long as the temperature and conditions allow, there are also cases of bearing fruit twice or even several times a year.

Growing tips:

1. Tidying up flowering shoots. About 2 months before flower bud differentiation, remove overly dense branches, shaded weak branches and diseased or pest-infested branches, leaving only 1-2 shoots per branch; this increases the light penetration of the canopy, helps concentrate nutrients and create good ventilation and light conditions, and promotes flower bud differentiation while preventing pests and diseases.

2. Cultivating and attracting flies for pollination. Before flowering in a longan orchard, pile up garbage in the orchard or compost bran manure, chicken manure, salted fish scraps, poultry and livestock innards, etc., which can cultivate and attract flies to come to the orchard to reproduce and pollinate. But using flies can only provide partial pollination.

3. Application of trace elements and calcium fertilizer. From flowering to the young fruit stage, mango can be treated with lime to reduce soil acidity and the content of harmful iron, aluminum and manganese, and to raise calcium levels. Generally apply 0.6-0.8 kg of lime per tree, or spray a 2% calcium chloride solution from flowering to fruit set. For the application of zinc and boron, spray once each of 0.2% zinc sulfate and 0.2% borax solution 10 days before flowering and at full bloom and after petal fall, to promote pollination and fruit set. When applying, it can be mixed into pesticide during pest and disease control for foliar feeding, along with irrigation. For soil application, use 100 g of zinc sulfate and 50 g of borax per tree, applied together with nitrogen, phosphorus and potassium fertilizer before the autumn shoots sprout.

4. Spraying flower- and fruit-retention agents: use 50-100 ppm gibberellin, spraying once every 15-20 days after petal fall, for a total of 2-3 sprays, which has a certain effect on raising the fruit-setting rate. Or use the following method: at full bloom: spray 50-70 ppm fruit-setting hormone (produced in Sichuan) + 0.3% borax. 1 week after petal fall: spray 50-70 ppm fruit-setting hormone (produced in Sichuan) or 300 times Duoxiaohao or 0.5-1 ppm of 1.8% Aiduoshou + 0.2% monopotassium phosphate. 2-3 weeks after flowering: spray 30-50 ppm “920” plus 0.3% urea.

5. Topdressing. (1) Rhizosphere topdressing: from petal fall to the rapid swelling stage of young fruit, topdress according to tree vigor and fruit load. Fertilization is mainly nitrogen and potassium. For trees under 10 years old, apply 0.3-0.5 kg each of urea and potassium fertilizer per tree; for trees over 10 years old, apply 0.5-1.0 kg each of urea and potassium fertilizer per tree; trees with few fruits may skip nitrogen fertilizer and only supplement potassium fertilizer, applying 0.3-1.0 kg of potassium fertilizer per tree depending on tree age. During fruit growth, for weak trees with many fruits, an appropriate amount of nitrogen and potassium fertilizer can also be supplemented in June. (2) Foliar topdressing: spray once each of 0.3% boric acid and 0.2-0.3% monopotassium phosphate at full bloom, at the end of flowering, and at the young fruit stage.

6. Fruit thinning and pruning of fruit-bearing branches. Fruit thinning is carried out within 15-30 days after petal fall, when the young fruits are about the size of a peanut; keep only 2-4 fruits per cluster, with the central position being best, selecting larger young fruits with tender green color and strong growth vigor; the retained fruits should be evenly distributed within the canopy and among the branches, preferably so that the fruits do not press tightly against one another. After physiological fruit drop in mango, the cluster axis is difficult to shed naturally, so it should be cut off by hand to prevent the wind from scraping and injuring the fruit skin and affecting appearance. However, the Irwin and Jinhuang mango varieties should be retained.

7. Promoting coloring. For some varieties with attractive red skin, such as Hongmang No. 6 and Irwin mango, during pruning at the mid-fruit stage remove shaded weak branches, diseased and pest-infested branches and other branches blocking the fruit, so that each fruit receives sufficient light and colors evenly. Before bagging the fruit, spray 1-2 times with 70% nitrile sulfur quinone wettable powder, which can make Irwin mango's appearance red and glossy; spraying 50% benomyl wettable powder can promote delicate fruit skin and the production of bloom, and spraying 80% sulfur wettable powder can promote red-yellow skin color and the production of bloom.

8. Bagging. The fruit development period of mango is a time of high temperature and frequent rain, and bagging the fruit is the best way to protect it from pests and diseases. Before bagging, spray fungicides and insecticides first, or dip the paper bag in the liquid medicine and use it wet; after bagging, tie it tightly, and leave a drainage hole at the bottom of the bag to drain accumulated water. The size of the mango bag varies by variety; the general specifications are: length 22-30 cm, width 15-20 cm, and the paper bag material can consist of white wax paper, black kraft paper and non-woven fabric. The bagging time is generally after fruit set is basically stable, that is, after the second physiological fruit drop ends, when the fruit has grown to the size of an egg. Zihua mango is bagged about 35 days after petal fall, and Irwin mango 30-50 days before harvest, which favors fruit coloring. Jinhuang mango can be bagged earlier, or bagged 45 days before harvest.
