Mango Tree Flowers Falling causing you a lot of trouble? And you do not know what to do?

If this describes your situation, I’ll get straight to:

  • The causes of your trouble,
  • What to do about it, so that you can stop the problem FOREVER!

Ready?

Before we get to the solution to your problem, you have first to understand…

What Causes Mango Flower Drop?

There are four causes for mango flower drop namely:

  1. Mango powdery mildew disease,
  2. Soil nutrient deficiencies,
  3. Unsuccessful pollination,
  4. Lack of water/rainfall,

“Now that I have learned the causes of mango flower drop, what should I Do to Stop The trouble?

You may ask.

Solution to Stopping Mango Flower Drop

  1. Control mango powdery mildew
  2. Give your mango trees the right nutrients at all times
  3. Ensure the flowers are pollinated by keeping some beehives if you have a big orchard
  4. Irrigate your mango farm (preferably using drip irrigation) so that pollinated flowers develop into fruit.

We will look at each problem and solution in detail below.

Doing so will take a little more of your time.

However, it will be time well spent.

I assure you, “By the time you finish reading, you’ll never face mango flower drop FOREVER

To start us off, let us examine the major cause of mango flower drop.

Mango Powdery Mildew

A notorious fungus known as Odium Mangiferae causes Mango powdery mildew.

This fungus is found all over the World.

Most likely, “It could be the major cause of mango flower drop in your farm.”

The disease is so destructive to mangoes.

As we speak, there is no mango cultivar that is immune.

All mango varieties and cultivars are highly vulnerable to the fungus.

If the fungus is left uncontrolled, it can lead to 100% mango flower drop.

The fungus attacks the flowers, the foliage, even young fruits.

During the attack, it forms a white powdery mass over these plant parts.

If it grows on the flowers, and it is left uncontrolled, all your mango flowers will die.

You’ll wake up one morning to find your mango flowers have turned brown and are falling off the trees.

So how do you control mango powdery mildew?

If you are asking this question, you are covered.

I wrote a detailed post explaining, “How to Control Powdery Mildew in Mango.”

Follow the link above for details.

Soil Nutrient Deficiencies

During flowering, mango requires the following KEY elements to form fruits:

  • Boron,
  • Potassium,
  • Copper,
  • Iron,
  • Etc.

When these elements are in short supply (in the soil), your mango trees will be aborting the flowers.

And you’ll be wondering what is the cause of the problem.

If you want to have a mango tree that is productive, you ought to consider the soil nutrition.

For best yields, the soil should be balanced.

By this I mean, “the Soil should have all the necessary minerals for plant growth.

It should have both the macro and micro elements.

Ways to Prevent Soil Nutrition Deficiencies
  1. Apply farmyard manure to your orchard every year to increase soil organic matter and nitrogen,
  2. Conduct a soil test for a proper diagnosis of soil nutrient level,
  3. Use foliar feeds to correct deficiencies or to boost nutrient availability when trees are fruiting.

Unsuccessful Pollination;

For flowers to develop into fruits, pollination MUST take place.

Sometimes this does not happen.

The reason could be:

  • A shortage of pollinators like flies and bees.
  • Heavy rain during flowering.

The good news is “Rarely do bees and flies fail to pollinate mango flowers.”

In case lack of pollination is the cause of mango flower drop, consider having beehives in your farm.

When it comes to heavy rain preventing pollination, there’s nothing you can do.

The best you can do is grow mangoes at the right environment where there’s no heavy rain during flowering.
