Best Fertilizer For Mangosteen mangosteen

Mangosteen, often termed as the “Queen of Fruits,” is a tropical delicacy known not just for its rich flavor but also for its myriad of health benefits. Cultivating mangosteen requires patience, but with the right fertilizer, you can significantly enhance its growth and fruit yield. In this comprehensive guide, we delve deep into the ideal fertilizers for mangosteen and how they can optimize plant health.

Understanding Nutritional Needs

Before we delve into the specific fertilizers, it’s vital to understand the nutritional requirements of mangosteen.

Primary Nutrients:

  1. Nitrogen (N): Vital for leaf growth and overall plant vigor.
  2. Phosphorus (P): Essential for root development, flowering, and fruiting.
  3. Potassium (K): Promotes fruit quality and resistance to diseases.

Secondary and Micronutrients:

  1. Calcium (Ca): Aids in cell wall formation.
  2. Magnesium (Mg): A vital component for photosynthesis.
  3. Sulfur (S): Necessary for certain amino acids and vitamins.
  4. Iron (Fe), Manganese (Mn), Zinc (Zn), Copper (Cu), and Boron (B): Vital for various enzymatic and metabolic processes.

Top Fertilizer Choices for Mangosteen

1. Organic Compost

A rich organic compost is a slow-releasing fertilizer that offers a multitude of nutrients essential for mangosteen. It enhances soil texture, promotes microbial activity, and maintains soil pH.


  • Apply a 2-inch layer of well-decomposed compost around the base of the mangosteen tree, ensuring it doesn’t touch the trunk.

2. NPK Fertilizers

NPK fertilizers are synthetically produced and contain the three primary nutrients: Nitrogen, Phosphorus, and Potassium.


  • A balanced NPK ratio of 10-10-10 can be used for young mangosteen trees.
  • For mature trees bearing fruit, a 5-20-20 NPK ratio is recommended.

3. Liquid Seaweed Extract

Liquid seaweed is a powerhouse of micronutrients. Besides providing essential nutrients, it also offers growth hormones and enzymes beneficial for mangosteen.


  • Dilute the seaweed extract as per the product’s instructions.
  • Use the solution to water the mangosteen trees once every 2-3 weeks.

4. Fish Emulsion

Rich in nitrogen and other nutrients, fish emulsion serves as a quick-release fertilizer that provides an instant boost to mangosteen trees.


  • Mix the fish emulsion with water as directed on the label.
  • Apply to the soil around the mangosteen tree once a month.

5. Epsom Salt

Epsom salt contains magnesium and sulfur, two secondary nutrients beneficial for mangosteen.


  • Dissolve 2 tablespoons of Epsom salt in a gallon of water.
  • Water the mangosteen tree with this solution once every six weeks.

DIY Fertilizer for Mangosteen

There’s an undeniable allure that exotic fruits have always held for me. Among them, the mangosteen stands out, not just for its tantalizing taste, but also for the challenge it presents to cultivate. As someone passionate about growing diverse fruit varieties in my backyard, the mangosteen tree was an addition I eagerly looked forward to nurturing. But what I quickly realized was that like all delicate things, this ‘queen of fruits’ demanded special care, especially when it came to fertilization. Today, I’m excited to share my discovery of the best DIY fertilizer for mangosteen.

A Quest Born Out of Necessity

Having had success with off-the-shelf fertilizers for other plants, I naturally began there. However, the unique needs of the mangosteen tree, coupled with my desire for a more organic and sustainable approach, led me to explore DIY solutions. The quest was clear: to formulate a nutrient-rich mix that would respect the mangosteen’s tropical roots while being environmentally friendly.

The Ingredients that Made the Cut

After several iterations and a lot of muddy hands, I settled on a blend that’s as simple as it is effective:

  1. Worm Castings: Acting as a slow-release fertilizer, worm castings provide essential nutrients over time. Moreover, they enhance soil structure, promoting root growth.
  2. Eggshells: Ground into a fine powder, eggshells offer a natural source of calcium, crucial for strong cellular development in plants.
  3. Banana Peels: Packed with potassium, they support fruiting and flowering, ensuring a bountiful harvest.

The Magic Blend

Creating the mix is straightforward:

  1. For every 5 gallons of soil, I use 1 cup of worm castings.
  2. I add the powder of 10 crushed eggshells.
  3. Finally, I incorporate the peels of 3 bananas, ensuring they’re chopped finely.

Mixing these ingredients thoroughly with the soil ensures an even distribution of nutrients.

The Result?

After a few months of consistently using this blend, I could see a marked difference. The leaves on my mangosteen tree seemed greener and more robust. The fruits, when they came, were juicier and had that perfect balance of tartness and sweetness. The satisfaction of knowing that this yield was the result of an eco-friendly, homemade solution made the success even sweeter.

My journey with the mangosteen tree taught me the joys of experimentation and the rewards of persistence. While my DIY fertilizer recipe worked wonders for me, gardening is a deeply personal experience, and I encourage every enthusiast to find or tweak a formula that resonates with their philosophy and the specific needs of their plants. Happy gardening!

Fertilization Schedule: When and How Often?

Mangosteen trees should be fertilized regularly to meet their nutritional demands, especially during growth spurts and fruiting periods.

  • Young Trees (1-3 years): Fertilize every 3-4 months.
  • Mature Trees (4 years and above): Fertilize once before the flowering season and once after fruit harvest.

Final Thoughts

Incorporating the right fertilizer is a game-changer for cultivating lush mangosteen trees. While it’s important to cater to the nutritional needs of the tree, always remember that over-fertilization can be detrimental. Monitoring the tree’s growth, combined with regular soil tests, can help in refining the fertilization approach, ensuring optimal health and bountiful yields of the coveted mangosteen fruit.
