During the flowering stage of durian trees, several major nutrients play crucial roles in supporting healthy growth, flowering, and fruit development. Here are the major nutrients needed during durian flowering: 

Nitrogen (N): Nitrogen is essential for overall plant growth, and it plays a vital role in the formation of vegetative tissues, including leaves and stems. Adequate nitrogen is crucial for the development of healthy and robust durian flowers.

Phosphorus (P): Phosphorus is important for energy transfer within the plant and is a key component in forming flowers and fruits. It supports the development of strong root systems and contributes to the overall reproductive processes of the durian tree.

Potassium (K): Potassium is essential for synthesizing sugars and starches, which are crucial for flower and fruit development. It also helps move water and nutrients within the plant, contributing to overall plant health and resilience.

Boron (B): Boron is a micronutrient that is particularly important during flowering. It contributes to forming healthy flowers, pollen germination, and fruit setting. Boron deficiency can lead to poor fruit development.

It's important to note that the specific nutrient requirements can vary depending on the soil composition and the durian tree's individual needs. Conducting soil tests and regular monitoring can help determine the appropriate fertilization plan to support optimal flowering and fruiting in durian trees.

Therefore, AgroBridge suggests applying Complex Blue Special (Chloride free) and Wuxal Boron for the flowering stage of durian:
1. Complex Blue Special: Suitable for flower and fruit crops and Chloride free
2. WUXAL® Boron 11.0% N – 13.8% P2O5 – 9.6% B + TE: Concentrated foliar fertilizer to overcome boron deficiencies. Suitable for a wide variety of fruit and vegetable crops such as durian, and cucumber.
