Caring for durian trees requires meticulous attention and a proper fertilization process to achieve optimal yields. Minh Hung Company can provide you with a standard care process for durian trees. Based on this process, farmers can refer to and choose corresponding products (such as organic fertilizers, NPK fertilizers, or foliar fertilizers) that Minh Hung is supplying at local dealers.
PHASE 1
Restoring the plant and stimulating new shoots after harvest (January - February after harvest)
The goal is to cleanse the garden, regenerate new root systems, and nurture 2 to 3 strong, uniform shoots with thick leaves.
| STEP | PURPOSE | PRODUCT | DOSAGE (200 L SPRAYER) | APPLICATION METHOD |
|---|---|---|---|---|
| 1 | ORCHARD CLEANING & TRUNK DISINFECTION | FUNGIDIOXIDE | 100 ml | Thoroughly spray the entire trunk, branches, and leaves until fully wet to remove algae, pink disease fungus, and Phytophthora. |
| 2 | CONTROL OF ROOT-KNOT NEMATODES | PARA-KNOT | 200 ml | Drench evenly around the tree canopy area. Apply early to protect newly developing young roots. |
| 3 | ROOT STIMULATION & SHOOT DEVELOPMENT | MH STRONGFRUIT 30-20-10 | 300 g | Foliar spray: When the tree begins bud break (new shoot emergence), spray periodically every 7–10 days. |
| 3 | ROOT STIMULATION & SHOOT DEVELOPMENT | MIHU ORFAXTRA / ORGAFARM BASIC | 500 ml (equivalent to 1 L per 400 L of water) | Root drench: Apply simultaneously with the foliar spray to stimulate root development, promote vigorous shoot growth, and maintain lush green foliage. |
PHASE 2
Germination and Flowering Stimulation (Water Stress Period)
The goal is to help the plant transition to the reproductive stage, develop flower buds well, and produce bright, uniform blooms.
For the bud formation and flowering stimulation stage (water stress period), Minh Hung Company (Minh Hung AMTSC) provides specialized products with extremely high levels of Phosphorus (P) and Potassium (K) to effectively transition the plant from growth to reproduction.
To achieve the best results during the water stress period, you can follow these steps:
| SPRAY APPLICATION / STAGE | SPECIFIC MINH HUNG PRODUCT | PURPOSE & EFFECTS | DETAILED APPLICATION |
|---|---|---|---|
| 1st application: At the beginning of leaf maturation (when leaves turn dark green) | MH-DKP 41-54 | Promotes rapid leaf maturation and suppresses the development of young shoots, allowing nutrients to concentrate on flower bud formation. | Spray evenly to thoroughly wet the leaf surfaces, promoting rapid and uniform leaf maturation in preparation for the reproductive stage. |
| 2nd application: 7–10 days after the first application (during the water-stress period) | MH STIM (0-44-44) | Strongly stimulates flower bud differentiation, promoting clear, uniform, and synchronized flower bud development. | Spray directly onto the lower buds of the branches where flowering is expected. |
| Supplement: During flower bud induction applications | NUTRIMAX MH (Chelated Trace Elements) | Provides essential minerals in chelated form to support flower bud differentiation and help reduce flower bud drop. | Apply in combination with MH-DKP or MH STIM to enhance flower bud development and promote healthy flower buds. |
PHASE 3
Flowering and Fruit Set Enhancement (From the time the flower buds appear until before pollination)
During the period from the emergence of the durian flower to before pollination, providing the right essential nutrients is crucial for plump flowers, strong flower stalks, and increased fruit set.
Below are recommended products from Minh Hung Company (Minh Hung AMTSC) for this stage:
| STAGE | SPECIFIC PRODUCT | PURPOSE & BENEFITS | APPLICATION METHOD |
|---|---|---|---|
| 1. Flower clusters reach 3–5 cm in length(Promoting large and healthy flower clusters) | AMINO 22 or MIHU ORGAXTRA combined with COMBI-MH (Chelated Trace Elements) | • Amino Acids: Provide energy to promote large, healthy, and uniform flower clusters while enhancing plant resistance.• Chelated Trace Elements: Rapidly absorbed to help prevent elongated, weak flower stalks and reduce flower stalk constriction. | Spray directly onto the flowers and flower-bearing branches every 7–10 days. |
| 2. 10–15 days before flowering(Enhancing pollen viability & fruit set) | NUTRIMAX MH | • Calcium: Strengthens cell walls and flower stalks, helping reduce flower and young fruit drop caused by unfavorable weather conditions.• Boron (B): Enhances pollen viability, supports effective pollination, and promotes higher and more uniform fruit set. | Apply 1–2 supplemental sprays before flowering begins. |
PHASE 4
Nurturing young fruit and preventing physiological fruit drop (From pollination to the 8th week)
The period from pollination to the 8th week is a critical time for durian cultivation. To prevent premature fruit drop, improve fruit shape, and effectively manage new shoots, Minh Hung Company (Minh Hung AMTSC) offers the following specialized product line:
| STAGE / CONDITION | PRODUCT COMBINATION | DOSAGE (200 L SPRAYER) | PURPOSE / BENEFITS |
|---|---|---|---|
| 7–10 days after flowering | NUTRIMAX + VIUSID AGRO + NOVA 20-20-20+TE | 25 g NutrIMAX + 40 ml VIUSID AGRO + 200 g NOVA | Young fruit development: Promotes firm fruit set and helps reduce early physiological fruit drop. |
| Fruit reaches lime size | NUTRIMAX + VIUSID AGRO + NOVA 20-20-20+TE | 25 g NutrIMAX + 40 ml VIUSID AGRO + 200 g NOVA | Fruit development & appearance: Promotes uniform fruit growth and supports green spines, bright skin, and attractive fruit appearance. |
| During periods of heavy rainfall | FUNGIDIOXIDE | Follow the dosage instructions on the product label. | Disease prevention: Helps prevent Phytophthora infection associated with fruit rot, pink disease, and gummosis. |
| When the tree begins to produce young shoots | MH STIM (0-44-44) or MH-DKP 41-54 | Follow the dosage instructions on the product label. | Immediate shoot suppression: Reduces nutrient competition between young shoots and developing fruits, helping prevent excessive fruit drop. |
Note: During this stage, it is important to maintain stable soil moisture. Avoid situations where the soil becomes too dry followed by sudden overwatering or heavy rain, as this can cause water shock and lead to mass fruit drop.
Phase 5
Fruit enlargement, fruit repair, and improved flesh quality (From week 9 until before harvest)
The goal is to help the fruit grow quickly, develop evenly, have yellow, plump flesh, increase sweetness, and avoid being tough.
| PRODUCT GROUP | SPECIFIC PRODUCT | CORE BENEFITS | APPLICATION & DOSAGE |
|---|---|---|---|
| 1. FOLIAR/FRUIT SPRAY(Pulp development & fruit weight enhancement) | NUTRIFEED / POLY-FEED 16-8-34 | Provides readily available nutrients to promote rapid fruit growth, enhance pulp development, and improve the fruit’s characteristic color and flavor. Supplies balanced NPK and chelated micronutrients, supporting larger fruit segments, fuller arils, and attractive coloration. | Mix 400 g with 200 L of water. |
| 2. FOLIAR/FRUIT SPRAY(Enhancing sweetness & peel color) | MH-DKP 41-54 | Promotes photosynthesis and the synthesis of sugars and proteins. Enhances sweetness (Brix) and helps maintain an attractive green fruit peel. | Spray evenly onto the leaves and fruits when the fruit reaches 60–75 days of age. |
| 2. FOLIAR/FRUIT SPRAY(Enhancing sweetness & peel color) | NUTRIMAX MH(Chelated Trace Elements) | Provides magnesium, zinc, boron, iron, and other essential micronutrients. Helps prevent nutritional imbalances that may cause uneven pulp development. | Apply periodically in combination with foliar fertilization programs. |
| 3. FRUIT PROTECTION(Prevention of fruit rot) | FUNGIDIOXIDE | Provides rapid control of bacteria and Phytophthora. Helps prevent blossom-end fruit rot and pink disease. | Spray directly onto the fruit. Leaves no harmful residue or stains on the fruit peel. |
