Young durian trees need strong roots, healthy soil, and fast leaf development. A simple way to support this is by applying a balanced mix of humic acid and potassium nitrate. In this guide, we show you how to use this mixture correctly and explain the benefits for long-term durian growth.

🧪 What You Need

For each application around a young durian stump, prepare:

• 5 tablespoons of humic acid

• 5 tablespoons of potassium nitrate (KNO₃)

• 20 liters of clean water

• A watering can or backpack sprayer

🥣 Mixing Instructions

1. Fill a container with 20 liters of water.

2. Add 5 tablespoons of humic acid and stir well.

3. Add 5 tablespoons of potassium nitrate and mix until fully dissolved.

4. Apply the solution evenly around the base (stump) of the young durian tree.

🌿 Why This Works

✅ Potassium Nitrate:

• Nitrogen (N) helps durian trees grow new leaves and stems quickly.

• Potassium (K) strengthens cell walls, improves water movement, and increases resistance to disease.

✅ Humic Acid:

• Loosens compact soil and increases nutrient availability.

• Stimulates beneficial soil microbes like Trichoderma and photosynthetic bacteria.

• Helps the tree absorb fertilizers more efficiently.

Together, this mix creates a rich, living root zone, ideal for faster and healthier durian development.

📅 How Often to Apply?

• Every 2 to 4 weeks during the active growing season (avoid rainy days).

• Best applied early in the morning or late afternoon.

🌱 Results to Expect

• Faster shoot and root development

• Greener, more vibrant leaves

• Stronger disease resistance

• Better early fruiting performance in the future
