Buyer Guide to Mango Tree Fertilizers
Granular fertilizers are usually known to be slow-releasing. They often come in the shape of coarse powders or even pellets.
These pellets or coarse powders will break down slowly over a long period of time, and this occurs every time you water your plant.
Application of granular fertilizers will vary according to brand and NPK ratio.
Usually, the packaging asks you to add it into the planting hole before you will fill it in with the soil and plant.
This type of fertilizer is less efficient when it comes to the pre-planted application but is great for use when it comes to new plantings.
Granular fertilizers are cost-effective when bought in bulk, and they are easy to store.
These are natural fertilizers that contain ingredients from animals and plants. Animal ingredients can include fish meal, bone meal, and manure.
Plant ingredients can include rotten fruits and plant parts that are composted. The type of fertilizer also nourished the soil and improved your plant’s health.
It’s environmentally friendly, hence reducing water pollution since the runoff does not contain any chemicals.
Organic fertilizers are also made with renewable ingredients, which makes them a better long-term solution.
Organic fertilizers are also high in Nitrogen which makes them perfect for Mango trees since they require high nitrogen levels.
How To Fertilize Mango Trees
How you feed your Mango tree is dependant on the fertilizer type you use for your plant. Some might be chemical fertilizers; others can be organic.
Each fertilizer has its own components, which makes it difficult to generalize the steps you need to follow. The way you garden also matters how you fertilize your Mango tree.
Every fertilizer will have a set number of instructions on them that will give you all the directions you need.
Generally, slow-releasing fertilizer spikes need to be used once a year, and liquid concentrates need to be used once every two months.
All of these fertilizers have their cons and pros. But to understand your Mango tree needs, you will have to know the pH of the soil.
Mango trees need to have a pH of six to seven in order to thrive with the help of all the nutrients in the soil. You can feed your Mango tree with the most expensive and renowned fertilizers.
But if the pH levels are not right, then your plant will not grow well at all. To understand your soil pH, first, invest in a pH testing kit or have your soil tested for its pH level.
Once you figure out the soil pH, adjust the levels accordingly. You should do this before you start planting your Mango tree, but it’s still possible for you to adjust the pH after the tree matures.
Soil pH needs to be reviewed annually, and actions must be taken to neutralize it if it goes up or down. You can buy products from the market that helps balance out your soil pH level.
You should also be using fertilizers that keep the soil pH balanced. Another way for you to make sure that your Mango tree is getting enough nutrients is by mulching.
Mulching twice a year in spring and fall will produce the best Mango trees, especially if good organic compost is used.
Not only does mulching help lock the nutrients into the soil, but it also adjusts the pH level of the soil.
Mulching will also help your Mango tree absorb other micronutrients such as iron, magnesium, zinc, copper, and calcium.
How Often To Fertilize Mango Trees
When it comes to established and young mango trees, they need to be fertilized during the summer, fall, and spring seasons.
Any form of fertilizer can work, but slow-releasing is preferred since they can be added in all three seasons.
If you are using granular fertilizers, sprinkle them in the required amount around the drip line. Mango trees need more Nitrogen so that they can help with the growth of healthy foliage.
Once the Mango tree has been established and bears fruits, then the need for Nitrogen decreases.
When your mango thee starts to produce flowers and fruits, it is important to use an NPK ratio higher in phosphorus and potassium.
This change in NPK ratio encourages healthy blooms to develop fruits. Higher phosphorus and potassium levels will increase nutrient absorption and protect your plant against diseases.
Before you choose your Mango tree fertilizer, make sure you look into the type of soil it has been planted on.
It’s extremely important for you to measure the pH of your soil since it will increase your plant’s fruit production and keep it alive longer.
Investing in a soil pH test kit for yourself is a great investment since you need to measure the pH annually.
Once your soil has the perfect pH level, then you can add a fertilizer with the perfect NPK ratio.
Once you choose your favorite fertilizer, make sure your plant is supplied with the proper nutrients and do not over-fertilize it.
The type of fertilizer you choose for your plant will be rewarding either way since you will be boosting your plant’s growth and fruit production.
