Pomelo trees are bearing fruit for the Tết harvest. This stage lasts several months, so instead of applying fertilizer all at once, many protocols recommend dividing applications evenly once a month. This article follows the principle of right type – right time – right amount, using YaraMila Complex 12-11-18 as an example, according to Yara's citrus nutrition protocol. YaraMila Complex Composition (according to Yara) According to Yara Vietnam's product page (Yara Việt Nam, n.d.a):
- N 12%; P₂O₅ 11%; K₂O 18%.
- Mg 1.63%; S 8%; B 0.015%; Fe 0.2%; Mn 0.02%; Zn 0.02%.
- Granular form.
According to Yara, the potassium in the product is in sulfate form; nitrogen includes both nitrate and ammonium forms. Potassium is the highest among the three main nutrients, accompanied by magnesium, sulfur, and micronutrients. Fertilization Schedule for Pomelo during Fruit Development – Harvest (Yara) According to Yara's citrus nutrition protocol, on the page dedicated to pomelo, apply once a month, per tree (Yara Việt Nam, 2025):
- YaraMila Complex: 0.5 kg/tree.
- YaraLiva Nitrabor: 0.1 kg/tree.
- YaraSuna Organic Advance: 0.5–0.6 kg/tree (if used in the garden).
Total annual application per tree according to the protocol: 0.5 kg YaraMila Racer + 5.5 kg Complex + 1.2 kg Nitrabor + 1–1.2 kg YaraSuna. Yara notes that this is a general recommendation and needs to be adjusted according to cultivation conditions (Yara Việt Nam, 2025). The Complex product page on yara.vn does not have a dosage table; the dosage in this article is taken from Yara's protocol file. Illustrative example: for a garden of 100 pomelo trees, 50 kg of Complex and 10 kg of Nitrabor are needed each month. Effective Fertilization Methods 1. Spread evenly within the canopy projection, not concentrated near the trunk. 2. Water sufficiently after application; the rainy season may end early (Thúy Lam, 2026), so mulch the base. 3. Coastal gardens: measure salinity before watering (Dân Việt, 2026). 4. For weak trees with sparse fruit, adjust according to Yara's general recommendations. Conclusion For pomelo during the fruit development stage, Yara's protocol is to apply 0.5 kg of YaraMila Complex and 0.1 kg of YaraLiva Nitrabor per tree each month. Dividing applications monthly, spreading within the canopy, and maintaining moisture are the correct ways to apply the right type, at the right time, and in the right amount.
