When To Fertilize Mango Trees in Florida | 5 Best Tips

When to fertilize mango trees in Florida? Let’s find out.

But before moving ahead, let me quickly introduce Florida to you.

Florida is the most populous southeastern state in America. After Texas, it is the second-most populous state in Southern America.

To understand how agriculture takes place in Florida, you should understand its geography.

We have the Gulf of Mexico to its west, the Atlantic Ocean and Bahamas to its east, and the state of Alabama to its northwest.

When To Fertilize Mango Trees in Florida?

According to “The University of Florida Extension Service“, you can grow mangoes in the warmest areas of Florida.

Lee and Dade are some places in Florida where mangoes are grown commercially.

Notable.

Before talking about fertilizing them, let me quickly introduce mangoes to you.

Common Name:Mango
Plant Type:Fruit, tree
Sun Exposure:Full sun
Soil Type:Moist, loamy, well-drained
Soil pH:5.5 to 7.5

Here are the details.

Plant In Early Spring:

According to the “Florida State Horticultural Society”, you should plant mango trees in early spring.

Remember that they can also be planted in December or January during mild winters.

You should ensure that it is not exposed to any frost. Now, move on to the next step.

Select a Planting Site:

This can be crucial.

As I mentioned above, mango trees prefer a sunny spot. Plus, well-draining soil is good for them.

At this stage, you have to consider the tree’s mature size. Remember that your mango tree can reach 100 feet or more.

Similarly, the canopy can be 35 feet or more. Huge, right?

The idea is that you should consider the size of the mango tree when selecting a planting site.

Note: The seeds should be planted around 1/2 inch deep.

Now, let’s talk about fertilizing your mango tree.

When to Fertilize?

Overview: When to fertilize mango trees in Florida? Note that mango trees are most active in spring and fall. So, fertilize your plant when it is beginning to bloom to fulfil the nutrient requirement. Then, plan 2-4 fertilizer applications each year. But, you should avoid fertilizer applications in high heat or winter.

Here are the details.

  • Usually, the first application takes place one month after planting.

After that, fertilize your mango tree from April to September. Let me explain.

This is the active season for your mango tree and the nutrient requirement is high. This takes us straight to the next point.

  • Mango trees are most active in spring and fall.

The idea is that they require more nutrients at this stage. So, fertilize your plant when it is beginning to bloom.

This will give you great results.

Now the question is, which fertilizer to use?

  • For a young mango tree, use a balanced 6-6-6 fertilizer with 4% magnesium.

The University of Florida Extension Service suggests this.

Note that other balanced fertilizers, such as the 10-10-10 fertilizer, can also be used. The idea is that it should be used once a month in the first year of growth.

After this, move on to the next step.

  • Plan 2-4 fertilizer applications each year.

According to some people, 2 applications in spring and 2 applications in fall produce great results.

It does!

On the other hand, some people fertilize once in spring (for fruit production) and then in fall (to strengthen the plant).

This is good as well. I recommend you read the instructions on the package.

According to the climate of Florida, three to four applications are good.

  • You should avoid fertilizer applications in high heat or winter.

Can you guess why is this important?

Remember that high summer temperature leads to nitrogen burn. Plus, fertilizer applications in winter are not effective.

Here’s why.

The mango tree drops its leaves in late fall and there is no growth until spring. This is known as dormancy.

To be precise, the mango tree does not use nutrients from the soil during winter.

Simple, isn’t it?

  • Follow the instructions on the package.

This is something important.

The idea is that you should read the instructions to understand the application rate. Here are some things that you should consider:

For young mango trees, increase the fertilization frequency. This is because young trees need more nitrogen.

Do you know why is nitrogen important?

Nitrogen in fruits allows proper development of colour, fruit size, and flavour.

Remember that fertilizer application depends on your soil type and quality as well.

In general, increase the fertilizer applications as the tree grows.

You should be extremely careful. This is because overfertilizing can burn your plant.

How To Fertilize Mango Trees?

We have already discussed when to fertilize mango trees in Florida.

Now, let me walk you through this process.

  • Apply the fertilizer to the root zone.

Here’s a fact.

Mango trees have wide root systems and their roots can grow about 25 feet in any direction.

The idea is that you should spread the fertilizer evenly with your hand under the tree’s canopy.

In other words, spread it under the leaf drip line (area under the outer circumference of the tree branches).

The table below will help you better understand the fertilizing schedule for mangoes.

Age of the plant (Years)N (g)P (g)K (g)

Note that this is a general schedule.

For proper application rates, read the instructions on the fertilizer package.

When you are done spreading the fertilizer, move on to the next step.

  • Water it.

You do not want nutrients to be “sitting on top of the soil”.

This is exactly why we water the soil after fertilization. This allows the nutrients to go deep into the soil.

This is what we call water infiltration.

You should water the new trees 2-3 times in the first week.

Note: Around 80% water is required during the flowering and fruit development stages. You should stop irrigation 10-15 days before the harvest.

Pretty simple, right?

Now, let’s talk about the climate of Florida.

The Climate of Florida:

To better understand when to fertilize mango trees in Florida, let’s study its climate first.

Overview: The humid subtropical climate of Florida is great for mangoes. This is because mangoes can tolerate a wide range of climates. Generally, a warm to hot climate is preferred during fruit development. Plus, low rainfall and relative humidity are good during flowering, fruit setting and harvest.

Here are the details.

Summers:

  • The climate of Florida is what we call the “humid subtropical“.

This simply means that summers are hot and humid, while the winters are cool to mild.

In other words, there is a relatively high temperature and precipitation throughout the year.

Remember that mangoes grow well in areas with high temperatures (45 °C). For best growth, the average maximum temperature should be between 27-36 °C.

Can you guess the reason for the high temperature?

Humidity.

It refers to the amount of water vapour in the air. If there are more water vapours in the air, the humidity will be higher.

As humid air holds more heat than dry air, the temperate increases. Good for mangoes, isn’t it?

Winters:

You should know that cold weather and fertilizer are not a good fit.

As I mentioned earlier, winters in Florida are cold to mild. Now you might be wondering, why are winters mild in Florida?

  • The predominant tropical easterly winds keep the temperature warm during the winters.

As we discussed earlier, fertilizer applications should be avoided in winters. Now, let’s talk about rainfall.

Rainfall:

Rainfall is crucial for mangoes.

According to the University of Florida IFAS Extension, mangoes should be watered throughout the first two years to encourage growth.

Note that each tree should receive around 26 gallons of water per week. Notable.

climate of Florida

The idea is that rainfall provides water to the mango trees which increases the fruit yield.

Here are some other things that you should consider:

  • The average precipitation is around 53.7 inches.
  • In South Florida and the Keys, September is usually the rainiest month.

To be precise, the amount of water needed depends on the rainfall.

Now, let’s talk about sunshine.

Sunshine:

You should know that sunshine is essential if you want good fruit and flower production.

According to some sources, mango trees need full sun (around 8 hours of direct sunlight) on most days.

Note: Do not worry. Florida is known as the sunshine state.

The amount of sunshine is great all around the year. Typically, South Florida receives more sunshine than North.

In the same way, different cities receive different amounts of sunshine.

Now when you know about the climate requirement of mangoes, let’s move on to the next topic.

What Soil is Best For a Mango Tree?

If you are planning to grow mangoes, this is something that you should know.

  • As we discussed earlier, mango trees are deep-rooted plants. So, they grow well in lateritic, alluvial, sandy loam, and sandy soils.

Note that mangoes grow well in loamy, alluvial, well-drained, aerated and deep soils (2-2.5 m) rich in organic matter.

  • Mangoes grow well in slightly acidic soils.

You should know that a pH range of 5.5-7.5 is ideal for mango cultivation (neutral to acidic).

This is because they do not grow well in slightly alkaline soils. Simple, isn’t it?

  • Mango trees have a low tolerance for salty soils.

Let me explain this to you.

You should avoid chemical fertilizers that contain a high amount of salt. This is because mangoes are sensitive to saline conditions.

These are some things that you should consider. Now, let’s jump straight to the conclusion.

Wrapping Up:

So, there you have it.

When to fertilize mango trees in Florida? To recap, mango trees are most active in spring and fall.

According to some people, 2 applications in spring and 2 applications in fall produce great results.

The idea is that you should read the instructions carefully on the package. Note that a balanced 6-6-6 fertilizer with 4% magnesium is good for a young mango tree.
