Conditions for sprouting and preparing to make durian flowers
Health of durian tree
Plants need to be healthy, growing well and free of pests and diseases. At the same time, the tree must have 3 buds, each bud has 6-8 leaves to ensure enough nutrition for the flowering process. In addition, the tree needs to be 4-5 years old or older to be eligible for stable flower and fruit development.
Provides water and nutrients for plants
Before starting to make flowers, you need to make sure the plant is well watered and has enough nutrients. This helps the tree stay healthy and have enough energy to develop flowers and grow fruit later.
Ensure adequate plant health and provide enough water and nutrients
Technical instructions for making durian flowers
The technique of making durian flowers includes 5 steps: Fertilizing with phosphate, spraying to create sprouts, pulling cotton and buds, nurturing cotton, and removing pistils from bean pens. Please refer to:
Step 1. Apply phosphate root
– Timing: When the plant begins to bloom and the new buds are soft, this is the time when the plant needs a lot of nutrition to prepare for flowering.
– Preparation: Farmers need to clean the area under the trees, remove weeds so that the phosphate fertilizer dissolves well and penetrates the soil.
– Fertilization: Use phosphate fertilizer with balanced phosphorus (P) and potassium (K) content. Phosphorus fertilizer helps stimulate rooting, while potassium increases plant health.
– Dosage: About 100g for each tree, apply around the base within 2/3 of the foliage radius.
Step 2. Spray nucleation
– First time: Mix 500g of fertilizer eg Lan 86 and 500g eg 10-60-10 with 200 liters of water, then spray evenly on both the top and bottom of the leaves.
– Second time: Mix 500g VD Lan 86, 500g VD MKP and 50ml growth stimulant into 200 liters of water. Spray only on the inside of the leaves and the small branches below.
– Time: About 10 days after applying phosphorus, when the tree is ready to produce new buds.
– Sprouting solution: Use a product like blum mixed with water (500ml/200-400 liters of water).
– First spray: Spray evenly on leaves and stems, water directly under the root, then reduce watering for 15-20 days to create conditions for cotton sprouts to grow.
– Spray a second time: Spray a second time after watering a second time to ensure the plant has enough crab eyes.

Step 3. Pull cotton, pull buds
– Timing: When the crab eyes are 2-3cm long, stimulate new shoots along the crab eyes to avoid flower loss.
– Spraying and fertilizing: Spray foliar fertilizers, apply organic fertilizers and fertilizers with high nitrogen content to support plant growth.
– Stimulate buds: Spray gibberellin 10-15 ppm of cotton and leaf fertilizer N:P:K (2:1:1 flowers 3:1:1) to stimulate buds and flowers.
– Watering: Start watering lightly when the crab eyes are long, gradually increase the amount of water to avoid clogging the flowers.
– Disease prevention: Use disease prevention products to protect cotton from pests and fungi.
Pulling buds is an important technique for making durian flowers
Step 4. Nourish cotton
– Time: When the cotton has clearly formed, start nurturing the cotton.
– Limit base fertilizers: Avoid base fertilizers to avoid stimulating young leaves and reducing nutrition for cotton.
– Watering: Make sure to water regularly but avoid over-watering.
– Pest prevention: Spray appropriate pesticides and fungicides, prioritizing environmentally friendly products.
– Pruning cotton: Remove weak cotton so the plant can focus nutrients on healthy cotton.

Step 5. Pistil plant, pen nib bean
– Watering: Water early in the morning to keep the plant moist without getting the pistil wet.
– Limit cotton quality: Reduce the use of fungicides to protect natural pollination.
– Pruning: Remove weak flowers, keep healthy flowers to increase fruit quality.
– Fertilization: After 7-10 days of removing pistils, apply balanced NPK fertilizer to support fruit development.

Caring for durian after flowering
After the technique of making durian flowers is completed, the fruit growing stage needs careful care. Water regularly for optimal fruit development, but avoid waterlogging to avoid harming the roots. Fertilization needs to be balanced, focusing on potassium fertilizer to improve fruit quality. At the same time, prune weak and diseased branches so that the tree focuses its nutrients on the fruit.
It is necessary to monitor and prevent pests promptly to protect the fruit. Check the soil regularly and adjust the irrigation and fertilization schedule to suit each stage of fruit development to ensure the best development.
Vermicompost contains high nutritional and organic content, beneficial microorganisms (nitrogen-fixing, phosphate-degrading, cellulose-degrading microorganisms) used to process cotton (applied when processing off-season cotton) helps cotton grow well, thereby producing quality fruit. We invite you to refer to it for application in your garden.

Note the technique of making cotton for durian trees
When cultivating durian, pruning is an essential step to ensure the tree grows healthily and achieves high productivity. This is also a note in the technique of making durian flowers.
Many people may think that keeping a lot of flowers on the tree will increase the number of fruits, but in reality, if you do not prune the flowers, the tree will not have enough nutrients to grow flowers. This can lead to cotton becoming weak, malnourished and susceptible to pest attacks, causing cotton to drop.
In addition to pruning flowers, people also need to pay special attention to protecting the leaves of the plant. Pests, especially red spider mites, often appear during the watering period and can cause serious damage to the tree. Protecting the leaves and controlling pests will help the tree maintain good health, thereby supporting the flowering and development of the durian fruit.
Provide the right amount of fertilizer so that plants have enough nutrients to grow flowers and develop fruit. Make sure the tree always has enough moisture, especially during the flowering and fruit growing stages.
It can be seen that, in addition to applying the correct technique for making durian flowers, pruning the flowers and protecting the leaves of durian trees also need to be taken care of!

How to prune durian flowers properly
Pruning durian flowers helps the tree focus nutrients on the remaining flowers, improving fruit quality. When the flower cluster is about 3-5cm long, nutrients from the leaves will be transferred to grow the flower, so the fruits on high branches are often bigger and more delicious, so people can refer to the following how to prune durian flowers:
For level 1 branches: Place the first bunch of flowers 0.5-1.8m away from the trunk, depending on the age of the tree, with the larger the branch, the farther the distance. Avoid placing flowers near stems because they will grow poorly.
For level 2 branches: Keep the flower clusters on large, strong branches, avoid leaving the flowers at the tip of the branch. Choose bunches of flowers that are facing down and don’t let the flowers grow in the wrong position. Depending on the health of the branch, place 4-10 flower clusters/branch, 20-25cm apart.
Prune the flowers in a bunch: When the flowers are about 8-10cm long, people prune the flowers on the same bunch, keeping the flowers that are healthy, round, fat and pest-free. Make sure there are no more than 10 flowers/cluster.
To distinguish between batches of cotton, farmers can number each cotton plant and mark each batch of cotton with different color paint to easily manage and determine the time to collect cotton!

Common durian flower problems
Dried durian flowers
Dry cotton of durian is often due to lack of water, lack of nutrition, pests and unfavorable climatic conditions. To fix it, please refer to the following:
- Adjust irrigation water: Make sure plants receive enough water, avoid excess/lack of water, because lack of water can lead to lack of nutrition for cotton.
- Nutritional supplement: Provide organic and inorganic fertilizers under the roots to improve soil and root system. Liquid organic fertilizer can be used to help the soil become more porous and roots develop better.
- Foliar nutrient spraying: Use additional products to enhance photosynthesis, help cotton shine, develop full nutrition and resist adverse conditions.
- Fungal disease management: Use fungal disease control products such as Dimethomorph, Pyraclostrobin and others to effectively protect cotton from fungal diseases.

Falling durian flowers
Durian flower drop can be caused by lack of water, lack of nutrients (especially phosphorus and potassium), pests such as red spider mites and fungi, unstable climatic conditions such as sudden temperature changes. Please refer to the following methods:
- Provide enough water: Make sure to water the durian tree fully and regularly, especially during the flowering stage.
- Adequate fertilization: Use fertilizer containing phosphorus and potassium to provide necessary nutrients for plants and help maintain cotton.
- Pest control: Implement timely pest control measures, including using appropriate pesticides.

Caterpillars eat durian flowers
Female butterflies usually lay 50-60 eggs on durian flowers. When the larvae hatch, they penetrate into the cotton to eat cotton petals, male stamens and female pistils, causing durian flowers to fall. Because worms often appear on large and thick cotton bunches, it is difficult for people to detect them until they eat them out. Measures to prevent pests from eating durian flowers are as follows:
- Visit the garden regularly, especially when durian blooms.
- Collect and destroy fallen cotton to prevent pest growth.
- If pests are detected, spray biological pesticides to promptly eliminate pests.
