Causes And Prevention Of Premature Falling of Mango Fruits

Causes of premature falling of mango fruits from the tree are discussed and the tips to prevent it. 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.



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!

When I saw tiny baby mangoes fell 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.

When the mango tree begins to fruit, you will see a large number of tiny mangoes on the stalks, but most of them fall as they grow. Don't worry, this is natural.

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. 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, pests, insects, diseases, lack of fertilizer, wrong time of fertilization can cause the young fruits to fall off.

Water

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.

Temperature

  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.

Fertilizer

  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.

Mango Diseases & How to Treat Them?

The fruits fall off the tree due to some mango tree problems.
  1. Fungal disease such as anthracnose, Gummosis, sooty mold, and powdery mildew can cause premature dropping of mango fruit. Due to anthracnose, the infected mango fruits drop early from the tree and fruit that initially appears unaffected quickly decays upon ripening and also the tree start losing leaves.
  2. Due to powdery mildew fruit, foliage and stems are covered with a white powdery substance, whereas anthracnose causes dark spots on leaves.
  3. As the fallen diseased twigs, leaves and fruits on the ground are a potential source of infection, never allow them to remain on the ground for too long. Prune dead branches and leaves from the tree regularly to avoid any disease to the tree.
  4. Dispose of all infected parts of the plant the in the rubbish or burn them.
  5. Keep the area around the plant as weed free as possible.
  6. Use a fungicide if the fungal problem persists. If the tree is already affected by anthracnose, and/or powdery mildew infection, it is too late to spray for these now. To avoid these fungal disease problems in the future, spray trees when they begin to form flower spikes.
  7. For anthracnose, spray a copper fungicide and use a sulfur fungicide for powdery mildew. The Mango anthracnose can be controlled by a spray of garlic or ginger or turmeric leaves. Grind and add to water with some liquid dish washing soap.
If you can identify the cause of your premature dropping of the fruit, then you can try to isolate the cause and treat that.

How can you use the fallen unripe mangoes?
You may want to use the fallen unripe mangoes. Here are some of the suggestions:
  1. Use them in coriander-mint chutney.
  2. Peel, chop and use them in salads.
  3. Peel, chop an use them in sweet mango chutney.
