How to get thick, green durian foliage?
1. Understand the importance of leaves for durian trees:
- Leaves are the photosynthesis factory: Leaves are where the durian tree absorbs sunlight, converts nutrients and produces energy.
- Leaves help the tree respire: Leaves also take part in gas exchange, supplying oxygen to the tree and releasing carbon dioxide.
- Leaves help the tree transpire: Leaves help regulate the tree's temperature through transpiration.
2. Factors affecting leaf colour and thickness:
- Nutrition: Deficiencies in nutrients such as nitrogen, iron and magnesium make leaves yellow, thin and prone to drop.
- Light: Light that is too weak or too strong is bad for leaves. Moderate light helps leaves photosynthesise well and grow healthily.
- Water: Durian trees need enough water to carry nutrients to the leaves. However, overwatering can cause waterlogged roots.
- Soil: Loose, fertile, well-drained soil helps roots grow healthily and supply enough nutrients to the leaves.
- Pests and diseases: Pests and diseases attacking leaves damage them, reducing photosynthesis and affecting the tree's development.
- Weather: Harsh weather such as drought and frost also affects leaf colour and thickness.
3. Measures for thick, green durian leaves:
- Balanced fertilisation: Apply sufficient NPK, organic and microbial fertilisers to fully supply the tree's nutrients.
- Appropriate watering: Water regularly, avoiding too much or too little.
- Pruning: Remove diseased, old and weak branches to open up the canopy so leaves receive more light.
- Pest and disease control: Use registered crop protection products, as directed, to control leaf pests and diseases.
- Micronutrient supplements: Regularly supplement micronutrients such as iron and magnesium to keep leaves green.
- Use foliar fertilisers: Spray foliar fertilisers designed for fruit trees to supply nutrients to the leaves quickly.
- Also: Products containing iron dihydroporphine (photo-iron) can be used to help build thick, green foliage and limit damage from pests and diseases.
4. Some notes:
- Observe the trees regularly: Watch leaf colour and shape to detect abnormal signs early and act in time.
- Choose good planting material: Choose healthy durian varieties well adapted to the local climate and soil.
- Apply sustainable cultivation practices: Limit chemical use, increase organic fertiliser use and protect the environment.
Note: For good results, consult agricultural specialists or experienced durian growers.
