Mango Tree Not Producing: How To Get Mango Fruit

Mango Tree Not Producing: How To Get Mango Fruit

Renowned as one of the most popular fruits in the world, mango trees are found in tropical to subtropical climates and originating in the Indo-Burma region and native to India and Southeast Asia. Mango trees have been cultivated in India for more than 4,000 years and mango tree problems, such as no mango fruit on trees, have been duly noted and solutions found, which we will examine in this article.

Reasons for No Mango Fruit on Tree

From the family Anacardiaceae and related to cashews and pistachio, the most common mango tree problems are those related to the mango tree not producing. Becoming familiar with its causes is the first step in how to get mango fruit on your tree. Below are the most common reasons for non fruiting mango trees:


The most detrimental disease affecting non fruiting mango trees is called anthracnose, which attacks all parts of the tree but does the most damage to the flower panicles. Symptoms of anthracnose appear as black irregularly shaped lesions that gradually become larger and cause leaf spot, bloom blight, fruit staining and rot – resulting in non fruiting mango trees. It is best to plant an anthracnose resistant variety of mango tree in full sun where rainfall will quickly evaporate to avoid this problem.

Another major contributor to the mango tree not producing fruit is another fungal pathogen, powdery mildew. Powdery mildew attacks young fruit, flowers and foliage, leaving these areas covered with a white fungal powder and often developing lesions along the undersides of the leaves. Severe infections will destroy the panicles, subsequently affecting potential fruit set and production, hence a mango tree not producing fruit. Both of these diseases are exacerbated with the onset of heavy dew and rain. Early spring applications of sulfur and copper when the panicle is half its full size and again 10-21 days later will aid in eradication of this fungal pathogen.

To prevent these diseases, apply a coating of fungicide on the susceptible parts when the buds appear and begin to open and ending at harvest time.


Mites and scale insects can attack mango trees but generally do not result in the mango tree not producing fruit unless severe. Treating the tree with neem oil can help alleviate most pest issues.


Cold may be a factor in the mango tree not producing fruit. Mango trees are extremely susceptible to cold temperatures and should, therefore, be planted in the most protected area of the yard. Ideally, plant your mango tree 8-12 feet (2-3.5 m.) of the south or east side of the house in full sun to deter the issue of no mango fruit on trees.


Another stressor which may affect the non fruiting mango tree is over fertilizing. Heavy fertilization of the lawn near the mango tree may reduce fruiting since the mango tree’s root system spreads well beyond the drip line of the tree. Oftentimes, this results in an abundance of nitrogen in the soil. You can offset this by adding a phosphorus rich fertilizer or bone meal to the soil around your mango tree.

Similarly, overwatering, as with the use of lawn sprinklers, may reduce fruiting or fruit quality.


Severe pruning may be done to reduce the canopy height of very large trees, enabling an easier harvest and does not injure the tree; however, it may reduce fruit production from one to several cycles. Therefore, pruning should only take place whenever absolutely necessary for shaping or maintenance purposes. Otherwise, prune only to remove broken or diseased plant material.


Finally, the last consideration for your mango tree not producing fruit is age. Most mango trees are grafted and will not begin to bear fruit until three to five years after planting.

If you live in a tropical to subtropical area, the mango tree is really quite easy to grow as long as you manage the above potential problems affecting your mango tree.

Common Problems of Mango in the Florida Home Landscape

Mangos are grown in tropical and subtropical lowlands throughout the world. In Florida, mangos are grown commercially in Dade, Lee, and Palm Beach Counties and as dooryard trees in warm locations along the southeastern and southwestern coastal areas and along the southern shore of Lake Okeechobee. In Florida, there are different pest and disease affecting mango production but most of them are not intensive for home landscape. Homeowners should contact their local UF/IFAS Extension office for recommended control measures.

  1. The flowers on mango tree turn black

The most important disease of mango in Florida is anthracnose. The anthracnose fungus attacks flowers, young fruits, leaves, and twigs. It also appears as a storage disease of mature fruits. Symptoms appear as black, slightly sunken lesions of irregular shape, which gradually enlarge and cause blossom blight, leaf spotting, fruit staining, and fruit rot. Disease development is encouraged by rains or heavy dews. Prevention can be accomplished by maintaining a coating of fungicide on susceptible parts starting when bloom buds begin to expand and ending at harvest.

  1. There are brown spots on the mango tree leaves

Brown spots on the leaves of mango tree are another symptom of the disease anthracnose. Preventative sprays can reduce the risk of infection.

  1. The young trees wilt gradually

Verticillium wilt is usually observed in new trees planted on land previously used for vegetable production (especially tomatoes). This fungus attacks the tree roots and vascular (water-conducting) system, decreasing and blocking water movement into the tree. Symptoms of infection include leaf wilting, desiccation and browning, stem and limb dieback, and browning of the vascular tissues. Occasionally verticillium will kill young trees. Control consists of removing affected tree limbs by pruning.

  1. The mango fruits split

The unfavorable weather conditions (high temperature, heavy rainfall and humidity) may be the main reasons for fruit splitting in mango.

  1. Mango trees flower but not set fruit

The main reason why the mango trees flower but not setting fruit is anthracnose disease which attack all part of the trees but most damage occurs to the flower panicles. Sever infections will destroy the panicles and accordingly affecting potential fruit set and production.

Q. How to induce flowers on my mango and avocado trees

I had trimmed down my mango tree over a year and a half ago. It has a lot of new leaves, but it has not been flowering. What can I do to induce the flowers so that we can ha e some fruits. I read that you can use calcium nitrate. Is this a fertilizer that is readily available? I also heard that you can use diluted bleach at the root of the plant? I only see a couple of blossoms, but they just dried up without any fruits. Any help would be very much appreciated.

A heavy pruning will often cause the flowering process to halt for awhile. Calcium nitrate will not likely help with flowering, as nitrogen usually prevents flowering in excess. The calcium can help with deficiencies, but it will no, necessarily, help with flowering. Bleach can help with ornamentals, but it can also take away a few years of its lifespan also.

I would recommend letting them fully recover from the hard pruning, then adding potassium and phosphorus. You can also try spraying with cytokines, but this can be dangerous to your health if misused.

Causes And Prevention Of Premature Falling of Mango Fruits

Learn how to prevent mango flowers and fruits from falling by proper mango flower drop management. Many times it so happens that there are plenty of mango tree flowers but no fruits, so what to do if the tree does not produce fruits. Causes of premature and untimely fall of mango fruits from the tree are discussed and the tips to prevent fruit dropping. Improper watering, fertilizer and diseases may be the reason of deflowering in mango, banana trees and other fruit trees.

When my young mango tree in its 3rd year, it produced about 25 fruits for the first time, it was a matter of joy and excitement for me. I used to watch them daily growing slowly.

Mangoes Ripening on Tree

But after a few weeks, I noticed about half of them fell down after a storm. I was very sad to see that ultimately only two mangoes matured, but both were very very tasty! The question is in spite of so many flowers, the tree do not produce fruits because most of the fruits drop at an early stage. What causes premature fruit drop?

When I saw tiny baby mangoes falling from tree prematurely, then it was a matter of concern, however fruit drop in mango tree, specially in a young mango tree is quite common.

Causes of Premature Dropping of Fruits

The natural question is why mango fruits fall down in the garden prematurely? There are several causes of fruit drop as discussed below.

Dropping is Natural Process

The initial falling of mangoes from stalks is quite common and not due to any insects or other problem [1]. A tree cannot support all the heavy fruit set, only a certain percentage of it can mature to full size fruit. Dropping of some mango fruits is a normal thinning process of tree to properly utilize the available nutrients. The immature fruits are all competing for the available food and water. The strongest will survive.

There are, however, many factors that may be responsible for the tree to shed its fruits. The weather, dry weather or too much rain, high temperatures, inadequate soil moisture, lack of pollination and ovule abortion, embryo degeneration, pests, insects, diseases, lack of fertilizer, failure of fertilization, wrong time of fertilization and low photosynthate level can cause the young fruits to fall off [2].


Getting right amount of water is an important factor for the growth of a mango trees. Too much water can cause fruit dropping prematurely. Note that a mature mango tree do not require frequent watering. For a young tree, water about two times a week in the first year and thereafter after 4-5 days.


  1. Mango trees grow well in warm tropical climates. However, a mature tree can withstand low temperatures.
  2. Cover the tree to protect it from frost. Do not prune dead branches if the frost continues.
  3. The mango tree fruit may fall if there was a cold weather during bloom and fruit set. The cold damages the developing embryo in the seed, due to which the ethylene gas given off by the damaged embryo causes fruits to drop before maturity.


  1. Another reason for premature dropping of mangoes from a tree is improper or over fertilization.
  2. Use a complete fertilizer developed for fruit trees, with correct ratios of nitrogen (N), phosphorous (P) and potassium (K). Fertilise your tree with a fertilizer that has a higher P and K ratio. Too much nitrogen will damage flowers.
  3. You can also give an organic fertilizer to feed the tree.
  4. Regularly add organic compost to the plant.


Severe pruning of the mango tree may reduce fruit production for many fruiting cycles. Pruning should, therefore, only be done to remove broken or diseased plant stems and leaves.

Mango Diseases & How to Treat Them?

Hormonal Causes of Fruit Falling

About 50-70% of the mango fruits fail to mature and fall off because of the formation of abscission layer in their stalks, known as fruitlet abscission. Abscisic acid (ABA) is possibly involved in fruitlet abscission.

The abscission is result of fruit complex physiological phenomena during the first 3-4 weeks after pollination and accounts for over 90% loss of set fruitlets [4].

How To Prevent Mango Fruit Dropping

If you can identify the cause of your premature dropping of the fruit, then you can try to isolate the cause and treat that to stop fruit dropping. Then how to prevent mango flowers and fruits from falling?

Spray of Hormones

The fruit drop in mango tree can be controlled by applying some hormones. Spray of some hormones on blooms ensures fruit setting. Naphthalene Acetic Acid (NAA) and Gibberellic acid (GA3) are the most effective for improving fruit retention.

In a study in Ghana, the spray of GA3 (25 ppm) and NAA (25 ppm) resulted in increasing fruit set, fruit retention, fruit weight and yield [5].

Initial fruit set was substantially increased when sprays of 200 mg/l indole acetic acid (IAA) were applied to developing panicles [6,7].

On a study on Australian Kensington Pride mango, polyamines spray Spermine (SPM) (0.01mM) onto the mango panicles at full bloom stage resulted in reduced heavy fruitlet abscission and improved fruit yield [8].

If you follow the following tip, I am sure you will have a very good crop of healthy mangoes. I am following this tip and my mango tree is producing several mangoes every year, each weighing more than 300 g.

Tip: Fruit drop in mango can be controlled by a spray. As soon as you see the mango flowers to appear, spray the flowers with eco oil or pest oil, every week on flowers and growing mangoes. Continue this until the fruits grow to a large size, stop the spray at least 2 weeks before you intend to cut the fruits from the mango tree.

Mango trees: How to grow a mango tree

The mango, or Mangifera indica, is often called the ‘kings of fruits’ and it’s a summertime staple in household around the world.

WATCH: How to slice a mango

Australia produces around 46 000 tonnes of the fruit each year. Want to add to that number in your own backyard? Here’s how to grow a mango tree.


There are over 500 different cultivars of mango varying in colour shape and flavour, with Kensington Pride (or Bowen) being the most common amongst Australian growers. Check with your local nursery to find out which ones grow best in your area. Trees are mostly sold as grafted saplings but some varieties can be grown from the seed. Mango seeds usually take around eight years to produce fruit while grafted saplings take three to five.


Mangoes prefer tropical and subtropical climates with humid, hot summers and cool, dry, frost-free winters.


Choose an open, sunny position, sheltered from strong winds. If you’re growing a mango tree in cooler climate, plant your tree need a north-facing brick wall to utilise the heat radiating off it.

Mango trees will grow in almost any soil whether sandy, loam or clay, but they require good depth and drainage.


You can plant mango trees year-round, but the best time time to plant a mango tree is in autumn. Start by digging a hole and incorporating added organic matter such as compost or rotted cow manure. After planting the sapling to the same depth as its original container, form a mound around it to improve drainage and encourage establishment. Water it well and mulch with hay.

“Many mango trees grow quite large (10 metres tall or more) so it is important to consider their sheer size when deciding where to plant it within your backyard,” Yates Horticulture Consultant Angie Thomas says.


While your mango tree is young it will require regular watering, depending on its growth and your climate. Start by watering it every other day before gradually increasing the time between irrigation to once or twice a week for the first year.

It’s important to keep mango trees well-watered from spring to autumn but water sparingly in late winter, before the onset of flowering. Established trees don’t require much watering.


“ Give them a good feed with a potassium enriched complete fertiliser during the warmer months to encourage healthy stem and leaf growth, as well as promote flowering and fruiting,” Angie says.

Sandy soils require more fertiliser than loam or clay but keep in mind that y oung trees are sensitive to over-fertilising. Mulch the base of the tree with pea straw each spring.


Mango trees often attract fruit flies so cover each fruit with a fruit fly bag after they form.

They're also susceptible to Anthracnose – a fungal disease causing black spots on leaves and fruit. Plant where there is good air circulation and avoid wetting the foliage. Prune off affected parts, bag them and put them in the garbage bin to prevent the spread of the fungal spores.

Garden Clinic says that a common complaint is a lack of fruit.

“Mango fruit set depends on several factors," Greg Daley from Daley’s Fruit Tree Nursery says. "Temperatures below 10 deg when flowering (October) in the spring will reduce fruit set. Also wet weather during flowering can result in anthracnose infection which will cause fruit not to set.”


No pruning is usually needed. Train the tree to have a single main stem, with side branching within its first years of growth. Remove dead, damaged or diseased wood as seen.


Mangoes are ready to be harvested when the colour of the skin turns from green to yellow, orange or red. Fruit are usually ripe around 100 to 150 days after flowering.


Propagation by seed is only recommended for poly-embryonic mango varieties such as Kensington Pride. To do so, carefully slit the husk of the mango, remove the seed and plant it in a large pot with seed starter mix with the seed slightly protruding from above the soil surface. It's important that it remains at a consistent temperature of at least 21 degrees. Sprouting will usually occur within three weeks.

Mango trees can also be propagated by grafting, in which part of the parent tree (scion) is joined with a rooted plant (rootstock).

Do Mangoes Grow on Trees?

If you are only familiar with seeing mangoes (Mangifera indica) in your local grocery store or purchase products made from them like chutney, you probably wonder where this tasty tropical fruit comes from. Mangoes grow on large trees that perform well in tropical and subtropical areas of the world. The fruits have risen in popularity and now rank at the top of the most enjoyed tropical fruits along with pineapples and avocados.

Mango Tree Description

Mango trees develop into large, lush, evergreen trees with most cultivars requiring a large area in the landscape to reach their full size. However, dwarf varieties are available that grow well in large containers. Some of the tree’s basic characteristics include:

  • Size: If left unpruned, mango trees can grow as tall as 100 feet, with a width about half their height.
  • Foliage: Large, leathery and oblong green leaves grow up to 16 inches long and each leaf can live up to five years. Depending on the cultivar, immature foliage range in colors of amber, reddish, pink, yellow or a pale green.
  • Tree Shape: Mango trees develop into symmetrical, rounded canopies.
  • Flowers: In spring, large flower panicles with multiple branches form on the tips of branches. Each panicle grows up to 16 inches long and can hold anywhere from 500 to 4000 flowers. The majority of the flowers are male and the remainder bisexual.

Mango Tree Races

Mango trees are divided into two different races: Indochinese and Indian. Both types have the same requirements for growth and have similar looks, but there are differences between the two.

Indochinese Mango Trees

Indochinese mangos are more tolerant to humid conditions than Indian types, and are relatively resistant to mildew and anthracnose. Fruits are usually greenish or yellow and elongated. The seeds are polyembryonic, which means if you plant one the developing seedling will produce the same type of fruit as the parent tree.

Indian Mango Trees

Indian mango trees are less tolerant to humidity and more susceptible to mildew and anthracnose. The fruits are very colorful, usually in mixes of reds, purples, yellow and greens and oblong-shaped. The seeds are monoembryonic, which means if you plant a seed the fruit produced can be the same, superior or not as good as the parent tree.

Mango Fruit

Depending on your climate and variety of mango tree you are growing, mango fruit is ripe and ready for harvesting anywhere from May through September. The mangoes will ripen on the tree, but they can be picked when the fruits are still firm and have fully matured in size. In addition, it can take anywhere from several days to a week for the fruit to become ready for eating.

One good thing about mangoes are you don’t have to harvest all the fruit at one time. You can leave the fruit on the tree until you are ready to eat it. As the season continues and if you don’t pick the mangoes, the fruit will eventually drop off the tree.

Expert Tip: The flesh of the mango is ripe and ready to eat once it changes from white to a yellowish color. You do not eat the skin. Store your harvested mangoes in a location with temperatures between 70 to 75°F (21 to 24°C). After the mango is ripe, you can store it in the refrigerator. Wash the mango after picking to remove the sap. Otherwise, the sap causes spotting, which leads to rot.


I am sorry to say that you are not likely to receive much helpful advice when you supply so little information about your mango tree --- not even your location. Do you live in the tropics where a mango tree might be reasonably expected to grow, or are you trying to grow a containerized seedling?
A few brown or curled leaves might be due to several factors, including soil chemistry, moisture and temperature.

Highly skilled container growers using named dwarf varieties have been reported able to fruit mango trees in northern climates, but these instances are uncommon and the mangoes thus produced cannot rival a good field-grown mango. Trees grown in containers from supermarket seeds are essentially pets, not fruit producers, and are touchy and difficult to grow because of the conditions required.

There are not many people here who would try to grow a container mango tree, so if that is what you are doing you might have better luck on the container forum.
