Best Fertilizer For Mango Trees
Mango tree fertilizers come in different forms. Depending on how many trees you have and how much time you want to spend fertilizing, you can choose from organic mixtures that are formulated either as spikes, liquids, and granules.
These are a pre-measured, mess-free solution to fertilizing. You simply need to hammer them into the ground around your mango tree.
They offer a slow-release of nutrients to your tree at root level and can last up to nine months depending on which brand you buy. They are also considered to be people and pet safe because they are hidden below ground so there is less chance of little hands or paws reaching them.
They are a convenient way of saving time and effort but are generally more expensive then other fertilizing methods.
Liquid Concentrate Fertilizer
You’ll need to dilute the required amount of fertilizer with water in a watering can before distributing it around the base of the tree. Nutrients are then absorbed into the soil and carried to the root system.
The advantage of liquid feeds is they get to work straight away and help to keep the pH levels in your soil balanced. However, their concentrated formula means that there can be a tendency to over-feed and this can lead to root burn, especially in young mango trees.
Granules And Powders
Granules And Powders typically don’t require diluting. They can either be sprinkled around the trunk as a top dressing, or they can be dug in. Just follow the instructions on the product’s packaging to indicate the quantity required based on the size of your mango tree.
Organic Vs Inorganic
Choosing an organic or inorganic formula comes down to personal preference based on product results and ecological opinion. While they both have their own advantages and disadvantages, organic is mostly preferred to keep you and your edible trees and plants healthy.
Whatever your preference, always follow the manufacturer’s guidance when using these products and wash edible produce thoroughly before eating them.
Organic fertilizers are made up of 100% natural plant or animal matter and typically smell somewhat organic! They are kinder to the environment and will not harm people or pets provided you stick to the manufacturer’s recommendations.
Inorganic fertilizers are manufactured with chemical nutrient compounds. They usually have little or no odor but overuse or misuse of these products can leave behind hazardous chemicals which may harm your plants, not to mention people and pets and the surrounding area.
Mango Tree Fertilizer N-P-K
Both organic and inorganic fertilizers feature three numbers on their packaging. These numbers indicate the N-P-K ratio of the fertilizer. (N) stands for Nitrogen, (P) for Phosphorus, and (K) Potassium.
Young mango trees will benefit from a higher ratio of nitrogen to help with the development of healthy foliage growth early in the season, but once they start bearing fruit the need for nitrogen decreases.
Once flowering and fruiting begin mango trees need an increased ratio of phosphorus and potassium. This helps to develop healthy blooms and fruit, maintain nutrient absorption, and protect against disease.
However, it’s fine to use a single fertilizer product throughout eh growing season for convenience and still get great results. Look out for an N-P_K around 5-5-5. The plant’s ability to take in the nutrients depends on the soil pH and other trace elements. Think of it in terms of making the fertilizer digestible.
With that in mind, all of the products I have selected on the list below contain these key ingredients; natural phosphorus sources from rock phosphate, guano, blood meal, or bone meal to provide phosphorus and potassium that is derived naturally from seaweed or potassium sulfate.
Mulching with a good quality, organic compost will also help with the absorption of phosphorus and potassium.

How To Feed Mango Trees
The method you use to feed your mango trees is entirely dependant on the type of mango tree fertilizers you prefer to use. It has to suit your needs and the way in which you garden.
The reviews above of the top 5 mango tree fertilizers provide descriptions and directions on how to feed. Ranging from slow-release fertilizer spikes that are a once per year solution to the liquid concentrates that get to work immediately but need more regular feeds.
These fertilizers all have advantages and disadvantages but in order for your mango tree to be able to absorb all of these essential nutrients and to thrive they need to be planted in soil with a pH range of between 6 and 7. You can feed them all you like with the fanciest and most expensive of mango tree fertilizers but if the soil pH isn’t right, you will simply be wasting your money.
Get your soil pH tested or invest in a soil pH test kit if you don’t already have one and adjust the soil levels accordingly. Ideally, you should be doing this before you start planting but it is possible to adjust soil pH if you already have a planted mango tree in your garden.
You will need to review soil pH annually and may need to take action to neutralize it thereafter.
You can buy specific products to either lower or increase soil pH and in addition, you should be using mango tree fertilizers that help to bring the right balance too.
Another way to ensure your mango trees are absorbing nutrients is to mulch twice a year in spring and fall with good quality, organic compost.
This will not only help to lock in the nutrients you have added to adjust the soil pH but will also help with the absorption of other micronutrients that are beneficial to mango trees such as iron, magnesium, zinc, copper, and calcium.
When And How Often To Fertilize Mango Trees
For young and established mango trees feed in spring, summer, and fall with a slow-release fertilizer. If you are using granules or powder, sprinkle the required amount all around the drip line and water in.
As I said earlier in this article, young mango trees need a higher ratio of nitrogen to help with the development of healthy foliage growth. Once this is established and fruit-bearing begins, the need for nitrogen decreases.
As your mango tree begins flowering and fruiting it is important to increase the ratio of phosphorus and potassium. This encourages healthy blooms and fruit to develop. It will also help your mango tree keep up with nutrient absorption and protect against disease.
